How to create a Set of Strings in C# ?

Answer

To create a set of strings in C#, you can use the HashSet class.

✐ Examples

1 Create a Set of Strings using HashSet

In this example,

We import the System.Collections.Generic namespace to use the HashSet class.
We create a HashSet object named stringSet to store strings.
We use the Add() method to add strings to the set.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        HashSet<string> stringSet = new HashSet<string>();
        stringSet.Add("Apple");
        stringSet.Add("Banana");
        stringSet.Add("Orange");
        stringSet.Add("Grapes");
        Console.WriteLine("Set of strings: {{ {0} }}", string.Join(", ", stringSet));
    }
}

Output

Set of strings: { Apple, Banana, Orange, Grapes }

2 Create a Set of Strings using Collection Initialization

In this example,

We directly initialize the HashSet with strings using collection initialization syntax.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        HashSet<string> stringSet = new HashSet<string> { "Apple", "Banana", "Orange", "Grapes" };
        Console.WriteLine("Set of strings: {{ {0} }}", string.Join(", ", stringSet));
    }
}

Output

Set of strings: { Apple, Banana, Orange, Grapes }
