How to create 2-ValueTuple in C#?
Last Updated :

In C#, a pair or 2 value tuple is a value type tuple which holds two elements in it. You can create a pair of value tuple using two different ways:
- Using ValueTuple <T1, T2>(T1, T2) Constructor
- Using Create <T1, T2>(T1, T2) Method
Using ValueTuple <T1, T2>(T1, T2) Constructor
You can create a pair value tuple by using ValueTuple <T1, T2>(T1, T2) constructor. It initializes a new instance of the ValueTuple <T1, T2> struct. But when you create a value tuple using this constructor, then you have to specify the type of the element stored in the value tuple.
Syntax:
public ValueTuple (T1 item1, T2 item2);
Parameters:
- item1: It is the value of the first value tuple component.
- item2: It is the value of the second value tuple component.
Example:
using System;
class GFG {
static public void Main()
{
ValueTuple< string , string > MyTpl = new ValueTuple< string ,
string >( "Geeks" , "GFG" );
Console.WriteLine( "Component 1: " + MyTpl.Item1);
Console.WriteLine( "Component 2: " + MyTpl.Item2);
}
}
|
Output:
Component 1: Geeks
Component 2: GFG
Using Create <T1, T2>(T1, T2) Method
You can also create a pair value tuple with the help of Create <T1, T2>(T1, T2) method. When you use this method, then there is no need to specify the type of the elements stored in the value tuple.
Syntax:
public static ValueTuple<T1, T2> Create<T1, T2> (T1 item1, T2 item2);
Type Parameters:
- T1: It is the type of the value tuple’s first component.
- T2: It is the type of the value tuple’s second component.
Parameters:
- item1: It is the value of the value tuple’s first component.
- item2: It is the value of the value tuple’s second component.
Returns: This method returns a value tuple with two elements.
Example:
using System;
public class GFG {
static public void Main()
{
var MyTple = ValueTuple.Create( "Geeks123" , "gfg" );
Console.WriteLine( "Component 1: " + MyTple.Item1);
Console.WriteLine( "Component 2: " + MyTple.Item2);
}
}

Output:
Component 1: Geeks123
Component 2: gfg
