In this article, we would like to show you how to remove duplicated elements from List in C#.

Quick solution:

xxxxxxxxxx
 
List<string> list = new List<string> { "A", "A", "B" };
​
list = list.Distinct().ToList(); // ["A", "B"]

Practical example

Edit

In this example, we remove duplicates from the list using Distinct() method from System.Linq.

xxxxxxxxxx
 
using System;
using System.Linq;
using System.Collections.Generic;
​
public class Program
{
    public static void Main()
    {
        List<string> list = new List<string> { "A", "A", "B" };
​
        list = list.Distinct().ToList();
​
        foreach (string item in list)
            Console.WriteLine(item);
    }
}
