ValueTuple is a structure introduced in C# 7.0 which represents the value type Tuple. It allows you to store a data set which contains multiple values that may or may not be related to each other. Item4 Property is used to get the fourth unnamed element of the given value tuple. It is applicable on every value tuple like 4-ValueTuple, 5-ValueTuple, and so on.
Syntax:
public T4 Item4;
Here, T4 is the field value of a ValueTuple<> structure. This ValueTuple<> can be 4-ValueTuple, or 5-ValueTuple, or 6-ValueTuple, or 7-ValueTuple, or 8-ValueTuple.
Example: In the below code, you can see that we are accessing the fourth element of each value tuple.
// 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);
}

Example 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());
}
