C# Tuple<T1,T2,T3,T4,T5,T6> Class

Tuple<T1, T2, T3, T4, T5, T6> class creates a 6-tuple or sextuple. It represents a tuple that contains six elements. You can instantiate a Tuple<T1, T2, T3, T4, T5, T6> object by calling either the Tuple<T1, T2, T3, T4, T5, T6>(T1, T2, T3, T4, T5, T6) constructor or by the static Tuple.Create method.

• 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 out parameter.
• It allows the passing of multiple values to a method with the help of single parameters.
• It can also store duplicate elements.

Constructor

Tuple<T1, T2, T3, T4, T5, T6>(T1, T2, T3, T4, T5, T6)

Property

We can retrieve value of Tuple<T1, T2, T3, T4, T5, T6>(T1, T2, T3, T4, T5, T6) object by read-only Item<elementNumber> instance property.

• Item1: Gets the value of the object’s first component.
• Item2: Gets the value of the object’s second component.
• Item3: Gets the value of the object’s third component.
• Item4: Gets the value of the object’s fourth component.
• Item5: Gets the value of the object’s fifth component.
• Item6: Gets the value of the object’s sixth component.

Example: Creating six tuples using the tuple class constructor

// Using constructor and property of 
// Tuple<T1, T2, T3, T4, T5, T6> Class
using System;

class Geeks
{
	static public void Main()
	{
		// Creating 6-Tuple using constructor
		Tuple<int, int, int, string, int, string> tuple = 
          new Tuple<int, int, int, string, int, string>
          	(79, 34, 67, "Geeks", 44, "GeeksforGeeks");

		// Accessing the values
		Console.WriteLine("Value of the First Component: " + tuple.Item1);
		Console.WriteLine("Value of the Second Component: " + tuple.Item2);
		Console.WriteLine("Value of the Third Component: " + tuple.Item3);
		Console.WriteLine("Value of the Fourth Component: " + tuple.Item4);
		Console.WriteLine("Value of the Fifth Component: " + tuple.Item5);
		Console.WriteLine("Value of the Sixth Component: " + tuple.Item6);
	}
}

Output:

Value of the First Component: 79
Value of the Second Component: 34
Value of the Third Component: 67
Value of the Fourth Component: Geeks
Value of the Fifth Component: 44
Value of the Sixth Component: GeeksforGeeks

Methods

Example: Demonstration of Equals() Method.

// Using the tuple Equals() method
using System;

class Geeks
{
	static public void Main()
	{

		// Creating 6-Tuple
		// Using Tuple<T1, T2, T3, T4, T5, 
		// T6>(T1, T2, T3, T4, T5, T6) constructor
		Tuple<int, int, int, int, int, int> mytuple1 = new Tuple<int,
		int, int, int, int, int>(20, 40, 90, 89, 33, 66);

		Tuple<int, int, int, int, int, int> mytuple2 = new Tuple<int,
		int, int, int, int, int>(20, 40, 90, 89, 33, 66);

		// Using Equals method
		if (mytuple1.Equals(mytuple2))
			Console.WriteLine("Tuple Matched.");
		else
			Console.WriteLine("Tuple not Matched.");
	}
}

Tuple Matched.
