How to create a Set of size N in C# ?

Answer

To create a set of size N in C#, you can use the HashSet class from the System.Collections.Generic namespace.

✐ Examples

1 Create Set of Size N with Strings

In this example,

We include the necessary using directive using System.Collections.Generic; to use the HashSet class.
We create a new instance of HashSet named stringSet with an initial capacity of N.
We add different strings to the set using the Add method.
The initial capacity of the set determines its size.
Finally, we use the Count property of the set to get the size and print it to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        // Create a set of size N with strings
        HashSet<string> stringSet = new HashSet<string>(capacity: N);
        
        // Add items to the set
        stringSet.Add("apple");
        stringSet.Add("banana");
        stringSet.Add("cherry");

        // Get the size of the set
        int size = stringSet.Count;

        // Print the size
        Console.WriteLine("Size of stringSet: " + size);
    }
}

Output

Size of stringSet: N

2 Create Set of Size N with Integers

In this example,

We include the necessary using directive using System.Collections.Generic; to use the HashSet class.
We create a new instance of HashSet named intSet with an initial capacity of N.
We add different integers to the set using the Add method.
The initial capacity of the set determines its size.
Finally, we use the Count property of the set to get the size and print it to standard output.

C# Program

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        // Create a set of size N with integers
        HashSet<int> intSet = new HashSet<int>(capacity: N);
        
        // Add items to the set
        intSet.Add(1);
        intSet.Add(2);
        intSet.Add(3);

        // Get the size of the set
        int size = intSet.Count;

        // Print the size
        Console.WriteLine("Size of intSet: " + size);
    }
}

Output

Size of intSet: N
