How to create 1-Tuple or Singleton Tuple in C#?
In C#, a singleton tuple is a tuple that contains only one element and singleton tuple is also known as 1-tuple. You can create a 1-tuple using two different ways:
- Using Tuple<T1>(T1) Constructor
- Using the Create method
You can create a singleton tuple using Tuple <T1>(T1) constructor. It initializes a new instance of the Tuple<T1> 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);
Here, item1 is the value of the tuple’s only component.
Example:
// C# program to create singleton // tuple using tuple constructor using System; public class GFG { // Main method static public void Main() { // Creating tuple with one elements // Using Tuple<T1>(T1) constructor Tuple< string > My_Tuple = new Tuple< string >( "w3wiki" ); Console.WriteLine( "Element: " + My_Tuple.Item1); } } |
Element: w3wiki
You can also create a singleton 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> Create<T1> (T1 item1);
Here, item1 is the value of the tuple element and T1 is the type of the element stored in the tuple.
Return Type: This method returns the components of the singleton tuple whose value is item1.
Example:
// C# program to create 1-tuple // using create method using System; public class GFG { // Main method static public void Main() { // Creating tuple with one elements // Using Create method var My_Tuple = Tuple.Create( "Beginner" ); Console.WriteLine( "Element: " + My_Tuple.Item1); } } |
Element: Beginner
