How to get Third Element of the Tuple in C#?

To get the third element of a Tuple in C#, you use the Item3 property. Tuples in C# provide indexed properties (Item1, Item2, Item3, etc.) to access their elements by position.

Syntax

Following is the syntax to access the third element of a tuple −

var thirdElement = tuple.Item3;

You can also create tuples using the generic Tuple<T1, T2, T3, ...> class or the Tuple.Create() method −

var tuple1 = new Tuple<int, int, int>(10, 20, 30);
var tuple2 = Tuple.Create(10, 20, 30);

Using Item3 Property

The Item3 property directly returns the third element of the tuple. Here's a focused example −

using System;

public class Demo {
    public static void Main(String[] args) {
        var tuple = Tuple.Create(100, 200, 300, 400, 500);
        
        Console.WriteLine("First element: " + tuple.Item1);
        Console.WriteLine("Second element: " + tuple.Item2);
        Console.WriteLine("Third element: " + tuple.Item3);
        
        // Accessing third element in a variable
        int thirdElement = tuple.Item3;
        Console.WriteLine("Third element stored in variable: " + thirdElement);
    }
}

The output of the above code is −

First element: 100
Second element: 200
Third element: 300
Third element stored in variable: 300

Working with Different Data Types

Tuples can store elements of different data types. Here's an example accessing the third element from a mixed-type tuple −

using System;

public class Demo {
    public static void Main(String[] args) {
        var mixedTuple = Tuple.Create("John", 25, true, 85.5, "Engineer");
        
        Console.WriteLine("Name: " + mixedTuple.Item1);
        Console.WriteLine("Age: " + mixedTuple.Item2);
        Console.WriteLine("Is Active: " + mixedTuple.Item3);
        Console.WriteLine("Score: " + mixedTuple.Item4);
        Console.WriteLine("Profession: " + mixedTuple.Item5);
        
        // Accessing third element specifically
        bool isActive = mixedTuple.Item3;
        Console.WriteLine("Third element (Is Active): " + isActive);
    }
}

The output of the above code is −

Name: John
Age: 25
Is Active: True
Score: 85.5
Profession: Engineer
Third element (Is Active): True

Tuple with Seven Elements

Here's an example demonstrating access to the third element in a larger tuple −

using System;

public class Demo {
    public static void Main(String[] args) {
        var tuple = Tuple.Create(1200, 1500, 2200, 2700, 3100, 3500, 4500);
        
        Console.WriteLine("HashCode of Tuple = " + tuple.GetHashCode());
        Console.WriteLine("Tuple Item 1st = " + tuple.Item1);
        Console.WriteLine("Tuple Item 2nd = " + tuple.Item2);
        Console.WriteLine("Tuple Item 3rd = " + tuple.Item3);
        Console.WriteLine("Tuple Item 4th = " + tuple.Item4);
        Console.WriteLine("Tuple Item 5th = " + tuple.Item5);
        Console.WriteLine("Tuple Item 6th = " + tuple.Item6);
        Console.WriteLine("Tuple Item 7th = " + tuple.Item7);
        
        // Highlighting third element access
        Console.WriteLine("The third element is: " + tuple.Item3);
    }
}

The output of the above code is −

HashCode of Tuple = -737223690
Tuple Item 1st = 1200
Tuple Item 2nd = 1500
Tuple Item 3rd = 2200
Tuple Item 4th = 2700
Tuple Item 5th = 3100
Tuple Item 6th = 3500
Tuple Item 7th = 4500
The third element is: 2200

Conclusion

Accessing the third element of a tuple in C# is straightforward using the Item3 property. This indexed approach works consistently regardless of the tuple's size or the data types it contains, making it easy to retrieve specific elements by their position.
