Dictionaries (9 Snippets)
In C#, dictionaries serve as a robust and flexible data structure for connecting pairs of elements. Consider using a dictionary to tally the frequency of words present in this text.
The dictionary’s keys would represent distinct words found in this text, with each word linked to its respective count. This type of structure proves highly beneficial in numerous scenarios. Now, let’s delve into a few prevalent dictionary operations in C#!
Merging Two Dictionaries
Combining two dictionaries is a common operation when working with data structures in C#. However, merging dictionaries can be tricky, especially when there are duplicate keys. Here are some solutions to handle these cases:
Dictionary<string, string> dict1 = new Dictionary<string, string> { { "Superman", "Flight" } };
Dictionary<string, string> dict2 = new Dictionary<string, string> { { "Batman", "Gadgets" } };
// Using LINQ
var merged = dict1.Concat(dict2).ToDictionary(x => x.Key, x => x.Value);
// Using a foreach loop
foreach (var item in dict2)
{
dict1[item.Key] = item.Value;
}
// Using the Union extension method
var merged2 = dict1.Union(dict2).ToDictionary(x => x.Key, x => x.Value);
Inverting a Dictionary
Is there a scenario where you might consider swapping the keys and values of a dictionary? This operation can be complicated, especially when dealing with non-unique values or non-hashable values. Here are some solutions for simple cases:
Dictionary<string, string> heroesAbilities = new Dictionary<string, string>
{
{ "Flash", "Super Speed" },
{ "Green Lantern", "Power Ring" },
{ "Aquaman", "Atlantean Strength" }
};
// Inverting the dictionary using LINQ
var inverted = heroesAbilities.ToDictionary(x => x.Value, x => x.Key);
// Inverting the dictionary using a foreach loop
Dictionary<string, string> inverted2 = new Dictionary<string, string>();
foreach (var item in heroesAbilities)
{
inverted2[item.Value] = item.Key;
}
Performing a Reverse Dictionary Lookup
In some cases, you might want to perform a reverse lookup in a dictionary, meaning, you want to find a key based on a given value. This can be useful when the dictionary is too large to be inverted. Here are some ways to achieve this:
Dictionary<string, int> dimensions = new Dictionary<string, int>
{
{ "length", 10 },
{ "width", 20 },
{ "height", 30 }
};
int valueToFind = 20;
// Brute force solution -- single key
foreach (var item in dimensions)
{
if (item.Value == valueToFind)
{
Console.WriteLine($"{item.Key}: {item.Value}");
break;
}
}
// Brute force solution -- multiple keys
foreach (var item in dimensions)
{
if (item.Value == valueToFind)
{
Console.WriteLine($"{item.Key}: {item.Value}");
}
}
// Using LINQ -- single key
var key = dimensions.FirstOrDefault(x => x.Value == valueToFind).Key;
Console.WriteLine($"{key}: {valueToFind}");
// Using LINQ -- multiple keys
var keys = dimensions.Where(x => x.Value == valueToFind).Select(x => x.Key);
foreach (var k in keys)
{
Console.WriteLine($"{k}: {valueToFind}");
}
The above snippets demonstrate different ways to perform a reverse dictionary lookup in C#. Depending on the size of the dictionary and the desired output, you can choose the most appropriate method for your use case.
Input/Output (4 Snippets)
Frequent instances of I/O involve interactions with databases, files, and command-line interfaces. While C# effectively simplifies I/O operations, certain complexities remain. Let’s examine a few of these challenges!
Writing to the Same Line
Sometimes you just need to write to the same line in your C# console application. The Console.Write method allows you to do this without adding a newline at the end of your string:
Console.Write("The Office");
Console.Write(" Parks and Recreation");
Creating a C# Script Shortcut
Is there a way to conveniently execute a script with just a click of a button after developing it? Luckily, various methods enable you to achieve this.
One approach is to generate a batch file containing the subsequent code:
@echo off
csc /path/to/MyProgram.cs
MyProgram.exe
Checking if a File Exists
Luckily in C# it’s easy. The System.IO namespace provides a set of methods for working with files, such as checking if a file exists:
using System.IO;
// Check if file exists using File.Exists method
bool exists = File.Exists("/path/to/file");
Parsing a CSV File
C# offers intriguing applications in the realm of data manipulation, which often requires dealing with substantial amounts of raw data in diverse formats, such as text files and CSV files.
Fortunately, C# comes equipped with numerous built-in tools for handling various file formats. For instance, parsing a CSV file can be accomplished effortlessly:
using System;
using System.IO;
// Read all lines from the CSV file
string[] lines = File.ReadAllLines("/path/to/data.csv");
// Process each line
foreach (string line in lines)
{
// Split the line into fields
string[] fields = line.Split(',');
// Do something with the fields, e.g., print them
Console.WriteLine($"{fields[0]} - {fields[1]} - {fields[2]}");
}
Lists (27 Snippets)
Among various data structures, lists stand out as the most prevalent. In C#, a list represents a dynamic array that utilizes zero-based indexing. This means we can add and remove items without concerning ourselves with the underlying implementation, making lists highly intuitive.
Naturally, like other data structures mentioned here, lists present their own set of challenges. Let’s explore further!
Appending an Element to a List
As my interest in this collection grew, I became intrigued by the basics of C#. In other words, what tasks might beginners want to perform, and how many alternative approaches exist for accomplishing them? One such task is appending an element to a list.
C# offers numerous methods for adding items to lists. For instance, the widely-used Add() method is available. However, there are plenty of other options as well. Here are five:
// Statically defined list
List<int> myList = new List<int> {2, 5, 6};
// Appending using Add()
myList.Add(5); // [2, 5, 6, 5]
// Appending using AddRange()
myList.AddRange(new List<int> {9}); // [2, 5, 6, 5, 9]
// Appending using Insert()
myList.Insert(myList.Count, -4); // [2, 5, 6, 5, 9, -4]
// Appending using InsertRange()
myList.InsertRange(myList.Count, new List<int> {3}); // [2, 5, 6, 5, 9, -4, 3]
Retrieving the Last Item of a List
As we delve into lists, let’s discuss acquiring the final element of a list. In numerous languages, this typically requires a complex mathematical expression related to the list’s length. Would you believe that C# offers several more intriguing alternatives?
List<string> myList = new List<string> {"red", "blue", "green"};
// Get the last item with brute force using Count
string lastItem = myList[myList.Count - 1];
// Remove the last item from the list using RemoveAt
myList.RemoveAt(myList.Count - 1);
// Get the last item using Linq Last() method
lastItem = myList.Last();
Checking if a List Is Empty
For those with a background in statically typed languages such as Java or C++, the absence of static types in C# might seem unsettling. Indeed, not being aware of a variable’s type can be challenging at times; however, it also offers certain advantages
For example, C#’s type flexibility allows us to verify whether a list is empty through various techniques:
List<int> myList = new List<int>();
// Check if a list is empty by its Count
if (myList.Count == 0)
{
// the list is empty
}
// Check if a list is empty by its type flexibility **preferred method**
if (!myList.Any())
{
// the list is empty
}
Cloning a List
A fascinating aspect of programming for me is duplicating data types. In the context of the reference-based environment that we inhabit, it’s rarely a simple task, and this holds true for C# too.
Fortunately, when it comes to replicating a list, there are several methods available:
List<int> myList = new List<int> {27, 13, -11, 60, 39, 15};
// Clone a list by brute force
List<int> myDuplicateList = myList.Select(item => item).ToList();
// Clone a list with the List constructor
myDuplicateList = new List<int>(myList);
// Clone a list with the ToList() Linq extension method
myDuplicateList = myList.ToList(); // preferred method
// Clone a list with the DeepCopy method (requires custom implementation)
myDuplicateList = DeepCopy(myList);
Writing a List Comprehension
List comprehensions are a powerful feature in Python, but C# doesn’t have a direct equivalent. However, we can achieve similar functionality using LINQ (Language Integrated Query) in C#. LINQ is a powerful querying syntax that provides a concise and expressive way to work with collections. Here are some examples using LINQ:
var myList = new List<int> { 2, 5, -4, 6 };
// Duplicate a 1D list of constants
var duplicatedList = myList.Select(item => item).ToList();
// Duplicate and scale a 1D list of constants
var scaledList = myList.Select(item => 2 * item).ToList();
// Duplicate and filter out non-negatives from 1D list of constants
var filteredList = myList.Where(item => item < 0).ToList();
// Duplicate, filter, and scale a 1D list of constants
var filteredAndScaledList = myList.Where(item => item < 0).Select(item => 2 * item).ToList();
// Generate all possible pairs from two lists
var list1 = new List<int> { 1, 3, 5 };
var list2 = new List<int> { 2, 4, 6 };
var pairsList = list1.SelectMany(a => list2, (a, b) => (a, b)).ToList();
Summing Elements of Two Lists
Imagine having two lists, and your goal is to combine them into one list by merging their elements pairwise. In other words, you aim to add the first element of the first list to the first element of the second list and save the outcome in a new list. C# offers several methods to achieve this:
var ethernetDevices = new List<int> { 1, 7, 2, 8374163, 84302738 };
var usbDevices = new List<int> { 1, 7, 1, 2314567, 0 };
// Using LINQ's Zip method
var allDevices = ethernetDevices.Zip(usbDevices, (x, y) => x + y).ToList();
// Using a for loop
var allDevicesForLoop = new List<int>();
for (int i = 0; i < ethernetDevices.Count; i++)
{
allDevicesForLoop.Add(ethernetDevices[i] + usbDevices[i]);
}
Converting Two Lists Into a Dictionary
You might want to create a dictionary by mapping one list onto the other. Here’s how you can do that using LINQ in C#:
var columnNames = new List<string> { "id", "color", "style" };
var columnValues = new List<object> { 1, "red", "bold" };
// Convert two lists into a dictionary with LINQ
var nameToValueDict = columnNames.Zip(columnValues, (key, value) => new { key, value }).ToDictionary(x => x.key, x => x.value);
Sorting a List of Strings
Sorting strings can be a bit more complicated than sorting numbers, but fortunately, C# provides several options for sorting strings:
var myList = new List<string> { "leaf", "cherry", "fish" };
// Using the Sort method
myList.Sort();
// Using the Sort method with StringComparison.OrdinalIgnoreCase for case-insensitive sorting
myList.Sort(StringComparer.OrdinalIgnoreCase);
// Using the OrderBy method with LINQ
var sortedList = myList.OrderBy(x => x).ToList();
// Using the OrderBy method with LINQ for case-insensitive sorting
var sortedIgnoreCaseList = myList.OrderBy(x => x, StringComparer.OrdinalIgnoreCase).ToList();
Sorting a List of Dictionaries
You most likely want to organize a list of dictionaries in some order, right? Here’s how you can sort a list of dictionaries in C# using LINQ:
var csvMappingList = new List<Dictionary<string, object>>
{
new Dictionary<string, object> { { "Name", "Johnny" }, { "Age", 23 }, { "Favorite Color", "Blue" } },
new Dictionary<string, object> { { "Name", "Ally" }, { "Age", 41 }, { "Favorite Color", "Magenta" } },
new Dictionary<string, object> { { "Name", "Jasmine" }, { "Age", 29 }, { "Favorite Color", "Aqua" } }
};
// Sort by Age using LINQ's OrderBy method
var sortedList = csvMappingList.OrderBy(dict => (int)dict["Age"]).ToList();
These examples demonstrate some common use cases for collections in C#. Using these code snippets, you’ll be able to tackle everyday programming challenges more efficiently.
It has been said that programming is about understanding code rather than writing it. In this case here are some tests for exactly that. Take a look at it:
Comments are important in the code. Many times it has happened to read a code without comments from a couple of months ago and not understand where it comes from, what it does or why it is there. For that reason here are the options to make comments in C#:
// Here is an inline comment in C#
/* Here
is
a
multiline
comment
in
C#
*/
///
Testing Performance
Sometimes you want to compare the performance of different code snippets. C# provides a few straightforward options, including the Stopwatch class and the BenchmarkDotNet library. Take a look:
// Stopwatch solution
using System;
using System.Diagnostics;
Stopwatch stopwatch = new Stopwatch();
stopwatch.Start();
// example snippet
var result = new List<(int, int)>();
foreach (int a in new[] { 1, 3, 5 })
{
foreach (int b in new[] { 2, 4, 6 })
{
result.Add((a, b));
}
}
stopwatch.Stop();
Console.WriteLine($"Elapsed time: {stopwatch.Elapsed}");
// BenchmarkDotNet solution
// Install the BenchmarkDotNet NuGet package to use this solution
using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Running;
public class MyBenchmark
{
[Benchmark]
public List<(int, int)> TestSnippet()
{
var result = new List<(int, int)>();
foreach (int a in new[] { 1, 3, 5 })
{
foreach (int b in new[] { 2, 4, 6 })
{
result.Add((a, b));
}
}
return result;
}
}
public class Program
{
public static void Main(string[] args)
{
var summary = BenchmarkRunner.Run<MyBenchmark>();
}
}
Strings (14 Snippets)
They are commonly utilized for storing and manipulating text data such as names, email addresses, and more. Due to their importance, there are numerous string-related problems that developers often encounter. In this section, we will explore a few of those problems in the context of C#.
Comparing Strings
When working with strings, what I usually ask is: Is there any way to be able to compare them without much complexity?
Or if we go deeper: Do we need to know the alphabetical order? If the two strings are different? Or what?
There are different tools we can use for each scenario. Here’s a quick list of options:
string player1 = "Crosby";
string player2 = "Malkin";
string player3 = "Guentzel";
// Brute force comparison (equality only)
bool isSamePlayer = player1.Length == player3.Length;
if (isSamePlayer)
{
for (int i = 0; i < player1.Length; i++)
{
if (player1[i] != player3[i])
{
isSamePlayer = false;
break;
}
}
}
// Direct comparison
bool isEqual = player1 == player3; // False
bool isGreater = player1.CompareTo(player3) > 0; // False
bool isLessOrEqual = player2.CompareTo(player2) <= 0; // True
// Reference checking
bool isSameReference = ReferenceEquals(player1, player1); // True
bool isDifferentReference = ReferenceEquals(player2, player1); // False
Here you can see some options. For instance, we can check for equality using the == operator. If we only need to check alphabetical ordering, we can use the CompareTo() method. Likewise, C# has the ReferenceEquals() method for checking reference equality.
Checking for Substrings
A common task when working with strings is determining if a string contains a specific substring. In C#, there are a few ways to solve this problem:
string[] addresses = {
"123 Elm Street",
"531 Oak Street",
"678 Maple Street"
};
string street = "Elm Street";
// Brute force (not recommended)
foreach (string address in addresses)
{
int addressLength = address.Length;
int streetLength = street.Length;
for (int index = 0; index <= addressLength - streetLength; index++)
{
string substring = address.Substring(index, streetLength);
if (substring == street)
{
Console.WriteLine(address);
}
}
}
// The IndexOf() method
foreach (string address in addresses)
{
if (address.IndexOf(street) >= 0)
{
Console.WriteLine(address);
}
}
// The Contains() method (preferred)
foreach (string address in addresses)
{
if (address.Contains(street))
{
Console.WriteLine(address);
}
}
Formatting a String
Oftentimes, we need to format strings to display information in a more readable or structured manner. Here are some options:
string name = "John";
int age = 25;
// String formatting using concatenation
Console.WriteLine("My name is " + name + ", and I am " + age + " years old.");
// String formatting using composite formatting
Console.WriteLine("My name is {0}, and I am {1} years old.", name, age);
// String formatting using interpolation (C# 6.0+)
Console.WriteLine($"My name is {name}, and I am {age} years old");
Feel free to use any of these methods wherever you need them.
Converting a String to Lowercase
When formatting or comparing strings, sometimes it’s useful to convert all characters to lowercase. This can be helpful when checking for equality between two strings while ignoring casing differences. Here are a few ways to do that:
string hero = "All Might";
// Using ToLower() method
string output = hero.ToLower();
Splitting a String by Whitespace
Handling language concepts such as words and sentences can be challenging. The way to divide a string into words that almost everyone will think of at first is with spaces. Here’s how to do that in C#:
string myString = "Hi, fam!";
// Using the built-in Split() method
string[] words = myString.Split();
foreach (string word in words)
{
Console.WriteLine(word);
}

Exception Handling (3 Snippets)
Handling exceptions is an essential part of writing robust and maintainable code. In this section, we will explore a few common ways to handle exceptions in C#.
Basic Try-Catch Block
To handle exceptions using a try-catch block in C#:
try
{
// Code that may throw an exception
}
catch (Exception ex)
{
Console.WriteLine($"Error: {ex.Message}");
}
Catching Specific Exceptions

Console.WriteLine($"General error: {ex.Message}");
}
Using Finally Block
To execute code regardless of whether an exception was thrown or not, you can use the finally block in C#:
try
{
// Code that may throw an exception
}
catch (Exception ex)
{
Console.WriteLine($"Error: {ex.Message}");
}
finally
{
// Code that will always be executed
}
LINQ (10 Snippets)
Language Integrated Query (LINQ) is a powerful feature in C# for querying and manipulating data. In this section, we will explore some common LINQ operations using the System.Linq namespace.
Filtering a Collection
To filter a collection using LINQ, you can use the Where() method:
using System.Linq;
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
List<int> evenNumbers = numbers.Where(x => x % 2 == 0).ToList();
Selecting a Property from a Collection

{
Console.WriteLine(name);
}
}
Joining Collections
To join two collections using LINQ, you can use the Join() method:
using System.Linq;
List<string> names = new List<string> { "John", "Jane", "Doe" };
List<int> ages = new List<int> { 30, 25, 35 };
var nameAgePairs = names.Join(ages, name => names.IndexOf(name), age => ages.IndexOf(age), (name, age) => new { Name = name, Age = age });
foreach (var pair in nameAgePairs)
{
Console.WriteLine($"{pair.Name}: {pair.Age}");
}
Taking the First n Elements
To take the first n elements from a collection using LINQ, you can use the Take() method:
using System.Linq;
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
List<int> firstThreeNumbers = numbers.Take(3).ToList();
Skipping the First n Elements
To skip the first n elements from a collection using LINQ, you can use the Skip() method:
using System.Linq;
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
List<int> remainingNumbers = numbers.Skip(2).ToList();
Checking if an Element Exists
To check if an element exists in a collection using LINQ, you can use the Any() method:
using System.Linq;
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
bool hasEvenNumber = numbers.Any(x => x % 2 == 0);
Counting Elements
To count the number of elements in a collection using LINQ, you can use the Count() method:
using System.Linq;
List<int> numbers = new List<int> { 1, 2, 3, 4, 5 };
int evenNumberCount = numbers.Count(x => x % 2 == 0);
Aggregating Elements
To aggregate elements in a collection using LINQ, you can use the Aggregate() method:

using System.Threading;
using System.Threading.Tasks;
CancellationTokenSource cts = new CancellationTokenSource();
Task.Run(() => PrintNumbers(cts.Token), cts.Token);
cts.Cancel();
Handling Task Exceptions
To handle exceptions in a task, you can use a try-catch block inside the task:
using System.Threading.Tasks;
Task.Run(() =>
{
try
{
// Code that may throw an exception
}
catch (Exception ex)
{
Console.WriteLine($"Error: {ex.Message}");
}
});
