C# ValueTuple <T1,T2,T3,T4,T5,T6> Struct

Last Updated : 21 Jan, 2025

ValueTuple <T1, T2, T3, T4, T5, T6> struct in C# is part of the System namespace and is used to create a tuple that storessextuple or 6-ValueTuple. It offers a more lightweight, value-type tuple compared to the older Tuple class and provides better performance and memory management. The ValueTuple struct is a value type and mutable means the value of its elements can be modified. Some key features about tuples are mentioned below:

Mutable: The value of the Item(fields) can be changed after the tuple is created.
Type-Safe: The field is specified when the tuple is created, ensuring type safety.
Implements Interfaces: ValueTuple<T1, T2, T3, T4, T5, T6> implements several interfaces such as:
- IStructuralComparable
- IStructuralEquatable
- IComparable<ValueTuple<T1, T2, T3, T4, T5, T6>>
- IEquatable<ValueTuple<T1, T2, T3, T4, T5, T6>>
- ITuple: This makes it useful in various comparison and equality scenarios.

Constructor

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

Fields

The constructor of this ValueTuple initializes the tuple with six values. It is not a property, it is a field that can be accessed by ValueTuple<ElementNumber>.

Item1: Gets the value of the current ValueTuple<T1, T2, T3, T4, T5, T6> instance’s first element.
Item2: Gets the value of the current ValueTuple<T1, T2, T3, T4, T5, T6> instance’s second element.
Item3: Gets the value of the current ValueTuple<T1, T2, T3, T4, T5, T6> instance’s third element.
Item4: Gets the value of the current ValueTuple<T1, T2, T3, T4, T5, T6> instance’s fourth element.
Item5: Gets the value of the current ValueTuple<T1, T2, T3, T4, T5, T6> instance’s fifth element.
Item6: Gets the value of the current ValueTuple<T1, T2, T3, T4, T5, T6> instance’s sixth element.

Example 1:

// Demonstration of access to the // ValueTuple<T1, T2, T3, T4, T5, T6> element using System;  class Geeks { 	static public void Main() 	{ 		// Creating a value tuple using Create method  		var lib = ValueTuple.Create(3, "C#", "Geek", 		2025, "Programming", "English");  		// Display the element of the value-tuple  		Console.WriteLine("Details: "); 		Console.WriteLine("Book Id: {0}", lib.Item1); 		Console.WriteLine("Book Name: {0}", lib.Item2); 		Console.WriteLine("Author Name: {0}", lib.Item3); 		Console.WriteLine("Publication date: {0}", lib.Item4); 		Console.WriteLine("Gener: {0}", lib.Item5); 		Console.WriteLine("Language: {0}", lib.Item6); 	} }

Output

Details:  Book Id: 3 Book Name: C# Author Name: Geek Publication date: 2025 Gener: Programming Language: English

Explanation: In the above example create a ValueTuple with six elements of different types and print each element by field Item<elementNumber>.

Methods

Method	Description
CompareTo(ValueTuple)	It compares the current ValueTuple<T1> instance to a specified ValueTuple<T1> instance.
Equals(Object)	It returns a value that indicates whether the current ValueTuple<T1> instance equals a specified object.
Equals(ValueTuple<T1>)	It returns a value that indicates whether the current ValueTuple<T1> instance equals a specified ValueTuple<T1> instance.
GetHashCode()	It calculates the hash code for the current ValueTuple<T1> instance.
ToString()	It returns a string that represents the value of this ValueTuple<T1> instance.

Example 2:

// Demonstration of Equals() Method in ValueTuple using System;  class Geeks { 	static public void Main() 	{ 		// Creating 6-ValueTuple using Create method  		var T1 = ValueTuple.Create(1, 2, 3, 4, 5, 6); 		var T2 = ValueTuple.Create(1, 2, 3, 4, 5, 6);  		// Check if both the value  		// tuples are equal or not  		if (T1.Equals(T2)) { 			Console.WriteLine("Tuples Matched...!!"); 		} 		else { 			Console.WriteLine("Tuples Not Matched...!!"); 		} 	} }

Output

Tuples Matched...!!
