How to create 4-Tuple or quadruple in C#?

Last Updated : 11 Jul, 2025

In C#, a 4-tuple is a

that contains four elements and it is also known as

. You can create a 4-tuple using two different ways:

• Using Tuple<T1,T2,T3,T4>(T1, T2, T3, T4) Constructor
• Using the Create method

You can create 4-tuple using Tuple<T1, T2, T3, T4>(T1, T2, T3, T4) constructor. It initializes a new instance of the Tuple<T1, T2, T3, T4> class. But when you create a tuple using this constructor then

stored in the tuple.

public Tuple (T1 item1, T2 item2, T3 item3, T4 item4);

• item1: It is the value of the first tuple component.
• item2: It is the value of the second tuple component.
• item3: It is the value of the third tuple component.
• item4: It is the value of the fourth tuple component.

// C# program to create 4-tuple
// using the tuple constructor
using System;

public class GFG {

    // Main method
    static public void Main()
    {

        // Creating tuple with four elements
        // Using Tuple<T1, T2, T3, T4>(T1, 
        // T2, T3, t4) constructor
        Tuple<string, int, char, double> My_Tuple = new Tuple<string,
                  int, char, double>("GeeksforGeeks", 10, 'G', 20.4);

        Console.WriteLine("Element 1: " + My_Tuple.Item1);
        Console.WriteLine("Element 2: " + My_Tuple.Item2);
        Console.WriteLine("Element 3: " + My_Tuple.Item3);
        Console.WriteLine("Element 4: " + My_Tuple.Item4);
    }
}

Element 1: GeeksforGeeks
Element 2: 10
Element 3: G
Element 4: 20.4

You can also create 4-tuple with the help of Create method. When you use this method then

stored in the tuple.

public static Tuple<T1,T2,T3,T4> Create<T1, T2, T3, T4> (T1 item1, T2 item2, T3 item3, T4 item4);

• T1: It is the type of the first tuple component.
• T2: It is the type of the second tuple component.
• T3: It is the type of the third tuple component.
• T4: It is the type of the fourth tuple component.

• item1: It is the value of the first tuple component.
• item2: It is the value of the second tuple component.
• item3: It is the value of the third tuple component.
• item4: It is the value of the fourth tuple component.

This method returns 4-tuple whose value is

,

, and

.

// C# program to create 4-tuple
// using create method
using System;

public class GFG {

    // Main method
    static public void Main()
    {

        // Creating tuple with four elements
        // Using Create method
        var My_Tuple = Tuple.Create("Geeks", 20, 'f', 340.6);

        Console.WriteLine("Element 1: " + My_Tuple.Item1);
        Console.WriteLine("Element 2: " + My_Tuple.Item2);
        Console.WriteLine("Element 3: " + My_Tuple.Item3);
        Console.WriteLine("Element 4: " + My_Tuple.Item4);
    }
}

Element 1: Geeks
Element 2: 20
Element 3: f
Element 4: 340.6
