How to Remove Specific Item from a Set in C# ?

Answer

To remove a specific item from a set in C#, you can use the Remove method to delete the item from the set.

✐ Examples

1 Removing Item from Integer Set

In this example,

We create a HashSet named numberSet using the HashSet class from the System.Collections.Generic namespace, which contains integer values 1, 2, 3, 4, and 5.
We use the Remove method of numberSet to remove the item 3 from the set.
Finally, we print the modified set numberSet to see the removed item.

C# Program

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        HashSet<int> numberSet = new HashSet<int> { 1, 2, 3, 4, 5 };
        numberSet.Remove(3);

        foreach (int num in numberSet)
        {
            Console.WriteLine(num);
        }
    }
}

Output

2 Removing Item from String Set

In this example,

We create a HashSet named stringSet using the HashSet class from the System.Collections.Generic namespace, which contains string values "apple", "banana", "cherry", "date", and "grape".
We use the Remove method of stringSet to remove the item "cherry" from the set.
Finally, we print the modified set stringSet to see the removed item.

C# Program

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        HashSet<string> stringSet = new HashSet<string> { "apple", "banana", "cherry", "date", "grape" };
        stringSet.Remove("cherry");

        foreach (string str in stringSet)
        {
            Console.WriteLine(str);
        }
    }
}

Output

apple
banana
date
grape
