How to create 3-Tuple or Triple Tuple in C#?
  • Last Updated : 29 Nov, 2019

In C#, a 3-tuple is a tuple that contains three elements and it is also known as triple. You can create a 3-tuple using two different ways:

Using Tuple<T1,T2,T3>(T1, T2, T3) Constructor

You can create 3-tuple using Tuple<T1, T2,T3>(T1, T2, T3) constructor. It initializes a new instance of the Tuple<T1, T2, T3> class. But when you create a tuple using this constructor then you have to specify the type of the element stored in the tuple.

Syntax:



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

Parameters:

  • 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.

Example:




// C# program to create 3-tuple
// using the tuple constructor
using System;
  
public class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Creating tuple with three elements
        // Using Tuple<T1, T2, T3>(T1, T2, T3) constructor
        Tuple<string, int, char> My_Tuple = new Tuple<string, int, char>("GeeksforGeeks", 10, 'C#');
  
        Console.WriteLine("Element 1: " + My_Tuple.Item1);
        Console.WriteLine("Element 2: " + My_Tuple.Item2);
        Console.WriteLine("Element 3: " + My_Tuple.Item3);
    }
}
Output:
Element 1: GeeksforGeeks
Element 2: 10
Element 3: C#

Using Create Method

You can also create 3-tuple with the help of Create method. When you use this method then there is no need to specify the type of the elements stored in the tuple.

Syntax:

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

Type Parameters:

  • 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.

Parameters:

  • 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.

Return Type: This method returns 3-tuple whose value is item1, item2, and item3.

Example:




// C# program to create 3-tuple
// using create method
using System;
  
public class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Creating tuple with three 
        // elements using Create method
        var My_Tuple = Tuple.Create("Geeks", 20, 'f');
  
        Console.WriteLine("Element 1: " + My_Tuple.Item1);
        Console.WriteLine("Element 2: " + My_Tuple.Item2);
        Console.WriteLine("Element 3: " + My_Tuple.Item3);
    }
}
Output:
Element 1: Geeks
Element 2: 20
Element 3: f
