ValueTuple es una estructura introducida en C# 7.0 que representa el tipo de valor Tuple. Le permite almacenar un conjunto de datos que contiene múltiples valores que pueden o no estar relacionados entre sí. La propiedad Item4 se utiliza para obtener el cuarto elemento sin nombre de la tupla de valor dada. Es aplicable en cada tupla de valor como 4-ValueTuple, 5-ValueTuple, etc.
Sintaxis:
public T4 Item4;
Aquí, T4 es el valor de campo de una estructura ValueTuple<>. Este ValueTuple<> puede ser 4-ValueTuple, o 5-ValueTuple, o 6-ValueTuple, o 7-ValueTuple, o 8-ValueTuple.
Ejemplo: en el siguiente código, puede ver que estamos accediendo al cuarto elemento de cada tupla de valor.
// C# program to illustrate how to get
// the fourth element of value tuple
using System;
class GFG {
// Main Method
static public void Main()
{
Console.WriteLine("C# Topics:");
// Creating a value tuple
// with four elements
var ValTpl4 = ValueTuple.Create("Stack", "Dictionary",
"LinkedList", "Interface");
// Accessing the fourth element of
// 4-ValueTuple using Item property
Console.WriteLine(ValTpl4.Item4);
// Creating a value tuple with five elements
var ValTpl5 = ValueTuple.Create("Identifiers", "Data Types",
"Keywords", "Access Modifiers", "Operators");
// Accessing the fourth element of
// 5-ValueTuple using Item property
Console.WriteLine(ValTpl5.Item4);
// Creating a value tuple with six elements
var ValTpl6 = ValueTuple.Create("Nullable Types", "Class",
"Structure", "Indexers", "Switch Statement", "Loops");
// Accessing the fourth element of
// 6-ValueTuple using Item property
Console.WriteLine(ValTpl6.Item4);
// Creating a value tuple with seven elements
var ValTpl7 = ValueTuple.Create("Inheritance ", "Constructors",
"Encapsulation", "Abstraction", "Static Class",
"Partial Classes", "this keyword");
// Accessing the fourth element of
// 7-ValueTuple using Item property
Console.WriteLine(ValTpl7.Item4);
// Creating a value tuple with eight elements
var ValTpl8 = ValueTuple.Create("Methods", "Method Hiding",
"Optional Parameters", "Anonymous Method",
"Partial Methods", "Local Function", "Delegates",
"Destructors");
// Accessing the fourth element of
// 8-ValueTuple using Item property
Console.WriteLine(ValTpl8.Item4);
}
}

Ejemplo 2:
// C# program to get the hash code of
// fifth element in a value tuple
using System;
class GFG {
// Main method
static public void Main()
{
// Creating 5-ValueTuple
var My_Value_Tuple = (1004, "Rohit", "Computer Science",
24, "C#");
// Accessing fifth element of the value tuple
Console.WriteLine("Favourite programming Language: {0}",
My_Value_Tuple.Item5);
// Getting the hashcode of the fifth element
Console.WriteLine("Hash Code: {0}",
My_Value_Tuple.Item5.GetHashCode());
}
}
Favourite programming Language: C# Hash Code: -849950870
