How to get third Element of the ValueTuple in C#?

  • Last Updated : 23 Jul, 2019

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. Item3 Property is used to get the third unnamed element of the given value tuple. It is applicable on every value tuple like 3-ValueTuple, 4-ValueTuple, and so on.

Syntax:

public T3 Item3;

Here, T3 is the field value of a ValueTuple<> structure. This ValueTuple<> can be 3-ValueTuple, or 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 third element of each value tuple.




// C# program to illustrate how to get
// the third element of value tuple
using System;
  
class GFG {
  
    // Main Method
    static public void Main()
    {
  
        Console.WriteLine("C# Topics:");
  
        // Creating a value tuple
        // with three elements
        var ValTpl3 = ValueTuple.Create("ArrayList",
                                     "List", "Queue");
  
        // Accessing the third element of 
        // 3-ValueTuple using Item property
        Console.WriteLine(ValTpl3.Item3);
  
        // Creating a value tuple 
        // with four elements
        var ValTpl4 = ValueTuple.Create("Stack", "Dictionary",
                                "LinkedList", "Interface");
  
        // Accessing the third element of 
        // 4-ValueTuple using Item property
        Console.WriteLine(ValTpl4.Item3);
  
        // Creating a value tuple with five elements
        var ValTpl5 = ValueTuple.Create("Identifiers", "Data Types",
                    "Keywords", "Access Modifiers", "Operators");
  
        // Accessing the third element of 
        // 5-ValueTuple using Item property
        Console.WriteLine(ValTpl5.Item3);
  
        // Creating a value tuple with six elements
        var ValTpl6 = ValueTuple.Create("Nullable Types", "Class",
            "Structure", "Indexers", "Switch Statement", "Loops");
  
        // Accessing the third element of 
        // 6-ValueTuple using Item property
        Console.WriteLine(ValTpl6.Item3);
  
        // Creating a value tuple with seven elements
        var ValTpl7 = ValueTuple.Create("Inheritance ", "Constructors"
                        "Encapsulation", "Abstraction", "Static Class",
                                    "Partial Classes", "this keyword");
  
        // Accessing the third element of 
        // 7-ValueTuple using Item property
        Console.WriteLine(ValTpl7.Item3);
  
        // 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 third element of 
        // 8-ValueTuple using Item property
        Console.WriteLine(ValTpl8.Item3);
    }
}
Output:
C# Topics:
Queue
LinkedList
Keywords
Structure
Encapsulation
Optional Parameters
