How to create 2-tuple or pair tuple in C#?

Last Updated : 11 Jul, 2025

In C#, a 2-tuple is a

that contains two elements and it is also known as

. You can create a 2-tuple using two different ways:

• Using Tuple<T1,T2>(T1, T2) Constructor
• Using the Create method

You can create 2-tuple using Tuple<T1, T2>(T1, T2) constructor. It initializes a new instance of the Tuple<T1,T2> class. But when you create a tuple using this constructor then

stored in the tuple.

public Tuple (T1 item1, T2 item2);

• item1: It is the value of the first tuple component.
• item2: It is the value of the second tuple component.

// C# program to create 2-tuple
// using the tuple constructor
using System;

public class GFG {

    // Main method
    static public void Main()
    {

        // Creating tuple with two elements
        // Using Tuple<P1, P2>(T1, T2) constructor
        Tuple<string, int> My_Tuple = new Tuple<string, int>("GeeksforGeeks", 10);

        Console.WriteLine("Element 1: " + My_Tuple.Item1);
        Console.WriteLine("Element 2: " + My_Tuple.Item2);
    }
}

Element 1: GeeksforGeeks
Element 2: 10

You can also create 2-tuple with the help of Create method. When you use this method then

stored in the tuple.

public static Tuple<T1,T2> Create<T1, T2> (T1 item1, T2 item2);

• T1: It is the type of the first tuple component.
• T2: It is the type of the second tuple component.

• item1: It is the value of the first tuple component.
• item2: It is the value of the second tuple component.

This method returns 2-tuple whose value is

and

.

// C# program to create 2-tuple
// using create method
using System;

public class GFG {

    // Main method
    static public void Main()
    {

        // Creating tuple with two elements
        // Using Create method
        var My_Tuple = Tuple.Create("Geeks", 20);

        Console.WriteLine("Element 1: " + My_Tuple.Item1);
        Console.WriteLine("Element 2: " + My_Tuple.Item2);
    }
}

Element 1: Geeks
Element 2: 20
