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

Last Updated : 11 Jul, 2025

Tuple<T1, T2, T3, T4, T5> class creates a 5 Tuple or quintuple. It represents a tuple that contains five elements. We can instantiate a Tuple<T1, T2, T3, T4, T5> object by calling either the Tuple<T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) 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 multiple values to be passed to a method with the help of single parameters.
• It can also store duplicate elements.

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

We can retrieve the value of Tuple<T1, T2, T3, T4, T5> object’s elements using the read-only Item<ElementNumber> instance properties.

• Item1: Gets the value of the first component of the tuple.
• Item2: Gets the value of the second component of the tuple.
• Item3: Gets the value of the third component of the tuple.
• Item4: Gets the value of the fourth component of the tuple.
• Item5: Gets the value of the fifth component of the tuple.

Example:

using System;

class Geeks
{
	static public void Main()
	{
		// Creating 5-Tuple using Tuple constructor
		Tuple<int, int, int, string, int> t =
          new Tuple<int,int, int, string, int>
          	(79, 34, 67, "Geeks", 44);

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

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

There are some important methods which are used in tuples are given below:

Method

Description

Equals(Object)

Returns a value that indicates whether the current Tuple<T1, T2, T3, T4, T5> object is equal to a specified object.

GetHashCode()

Returns the hash code for the current Tuple<T1, T2, T3, T4, T5> object.

GetType()

Gets the Type of the current instance.

MemberwiseClone()

Creates a shallow copy of the current Object.

ToString()

Returns a string that represents the value of this Tuple<T1, T2, T3, T4, T5> instance.

Example: Demonstration of Equals() Method.

// Using constructor and property
// of Tuple Class
using System;

class Geeks
{
	static public void Main()
	{
		// Creating 5-Tuple using constructor
		Tuple<int, int, int, int, int> t1 = 
          new Tuple<int, int, int, int, int>
          	(20, 40, 90, 89, 33);

		Tuple<int, int, int, int, int> t2 = 
          new Tuple<int, int, int, int, int>
          	(20, 40, 90, 89, 33);

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