How to Sort a List in Descending Order in C# - Step by Step Examples

How to Sort a List in Descending Order in C# ?

Answer

To sort a list in descending order in C#, you can use the LINQ extension method OrderByDescending along with lambda expressions.


✐ Examples

1 Sort a List of Integers in Descending Order

In this example,

  1. We create a list named numbers with integer values.
  2. We use the LINQ extension method OrderByDescending with a lambda expression to sort the list in descending order based on integer values.
  3. Finally, we iterate through the sorted list and print its elements to the console.

C# Program

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        List<int> numbers = new List<int> { 5, 2, 8, 1, 3 };
        var sortedNumbers = numbers.OrderByDescending(num => num);

        // Print sorted list
        foreach (var num in sortedNumbers)
        {
            Console.Write(num + " ");
        }
        Console.WriteLine();
    }
}

Output

8 5 3 2 1

2 Sort a List of Strings in Descending Order

In this example,

  1. We create a list named words with string values.
  2. We use the LINQ extension method OrderByDescending with a lambda expression to sort the list in descending order based on string values.
  3. Finally, we iterate through the sorted list and print its elements to the console.

C# Program

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main()
    {
        List<string> words = new List<string> { "banana", "apple", "cherry" };
        var sortedWords = words.OrderByDescending(word => word);

        // Print sorted list
        foreach (var word in sortedWords)
        {
            Console.Write(word + " ");
        }
        Console.WriteLine();
    }
}

Output

cherry banana apple
