In C#, a 2-tuple is a tuple that contains two elements and it is also known as pair. You can create a 2-tuple using two different ways:
CSharp
CSharp
Using Tuple<T1,T2>(T1, T2) Constructor
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 you have to specify the type of the element stored in the tuple. Syntax:public Tuple (T1 item1, T2 item2);Parameters:
- 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);
}
}
Output:
Element 1: GeeksforGeeks Element 2: 10
Using Create Method
You can also create 2-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> Create<T1, T2> (T1 item1, T2 item2);Type Parameters:
- 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.
// 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);
}
}
Output:
