C# Tuple<T1,T2,T3,T4,T5,T6,T7> Class - GeeksforGeeks

Last Updated : 11 Jul, 2025

Tuple<T1, T2, T3, T4, T5, T6, T7> class creates a 7-tuple or septuple. It represents a tuple that contains seven elements. We can instantiate a Tuple<T1, T2, T3, T4, T5, T6, T7> object by calling either the Tuple<T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) 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.

Tuple<T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7)

We can retrieve value of Tuple<T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) object by read-only Item<elementNumber> instance property

• Item1: Gets the value of the first component of the tuple object.
• Item2: Gets the value of the second component of the tuple object.
• Item3: Gets the value of the third component of the tuple object
• Item4: Gets the value of the fourth component of the tuple object.
• Item5: Gets the value of the fifth component of the tuple object.
• Item6: Gets the value of the sixth component of the tuple object.
• Item7: Gets the value of the seventh component of the tuple object.

Example: Creating a 7-tuple using the constructor of the tuple class

// Using constructor and property of Tuple
// <T1, T2, T3, T4, T5, T6, T7> Class 
using System;

class Geeks
{
	static public void Main()
	{
		// Creating 7-Tuple using constructor 
		Tuple<int, int, int, string, int, string, int> tuple = 
          new Tuple<int,int, int, string, int, string, int>
          	(79, 34, 67, "Geeks",44, "GeeksforGeeks", 66);

		// 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);
		Console.WriteLine("Value of the Seventh Component: " + tuple.Item7);
	}
}

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
Value of the Seventh Component: 66

Method

Description

Equals(Object)

Returns a value that indicates whether the current Tuple object is equal to a specified object.

GetHashCode()

Returns a value that indicates whether the current Tuple object is equal to a specified object.

GetType()

Returns a value that indicates whether the current Tuple object equals a specified object.

MemberwiseClone()

Creates a shallow copy of the current Object.

ToString()

Creates a shallow copy of the current Object.

Example 2: Demonstration of Equals() Method

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

class Geeks
{
	static public void Main()
	{
		// Creating 7-Tuple 
		// Using Tuple<T1, T2, T3, T4, T5, T6, 
		// T7>(T1, T2, T3, T4, T5, T6, T7) constructor 
		Tuple<int, int, int, int, int, int, int> mytuple1 = 
          new Tuple<int,int, int, int, int, int, int>
         	(20, 40, 90, 89, 33, 66, 87);

		Tuple<int, int, int, int, int, int, int> mytuple2 = 
          new Tuple<int, int, int, int, int, int, int>
          	(20, 40, 90, 89, 33, 66, 87);

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