C# Tuple<T1> Class

Tuple<T1> class is used to create a 1-tuple or singleton which contains only a single element in it. We can instantiate a Tuple <T1> object by calling either the Tuple<T1> constructor or by the static Tuple.Create method. We can retrieve the value of the tuple’s single element by using the read-only Item1 instance property. There are some important points which are mentioned below:

• It implements the IStructuralComparable, IStructuralEquatable, and IComparable interface.
• It is defined under the System.namespace.
• It represents multiple data into a single data set.
• It allows us to create, manipulate, and access data sets.
• It returns multiple values from a method without using the out parameter.
• It allows multiple values to be passed to a method with the help of single parameters.
• It can also store duplicate elements.

Constructor

// Initializes a new instance of the Tuple<T1> class.
Tuple<T1>(T1)

Property

Item1: Gets the value of the Tuple<T1> object’s single element.

Example:

// C# program to illustrate the constructor 
// and property of class Tuple<T1> 
using System; 

class Geeks
{ 
	static public void Main() 
	{ 
		// Creating 1-Tuple 
		// Using Tuple<T1>(T1) 
		Tuple<int> t = new Tuple<int>(357); 

		// Accessing the values 
		Console.WriteLine("Value of Element: " + t.Item1); 
	} 
} 

Value of Element: 357

Tuple Methods

Example:

// C# program to determine the 
// given tuples are equal or not 
using System; 

class Geeks
{  
	static public void Main() 
	{ 

		// Creating 1-Tuple 
		// Using Tuple<T1>(T1) 
		Tuple<int> t1 = new Tuple<int>(22); 
		Tuple<int> t2 = new Tuple<int>(22); 

		// Using Equals method 
		if (t1.Equals(t2)) 
			Console.WriteLine("Tuple Matched."); 
		else 
			Console.WriteLine("Tuple not matched."); 
	} 
} 

Tuple Matched.
