In this article, we would like to show you how to clear HashSet in C#.

Quick solution:

xxxxxxxxxx
 
HashSet<string> myHashset = new HashSet<string> { "A", "B", "C" };
​
myHashset.Clear();

Practical example

Edit

In this example, we use Clear() method to remove all items from myHashset.

xxxxxxxxxx
 
using System;
using System.Collections.Generic;
​
public class Program
{
    public static void Main()
    {
​
        HashSet<string> myHashset = new HashSet<string> { "A", "B", "C" };
​
        Console.WriteLine("Before:");
        foreach (string item in myHashset)
            Console.WriteLine(item);
​
        myHashset.Clear(); // clear HashSet
​
        Console.WriteLine("\nAfter:");
        foreach (string item in myHashset)
            Console.WriteLine(item);
​
    }
}
