How to create 5-Tuple or quintuple in C#?

A 5-tuple or quintuple in C# is represented by the Tuple<T1, T2, T3, T4, T5> class, which is a data structure that holds exactly five elements of potentially different types. Each element can be accessed through its corresponding Item property.

Syntax

Following is the syntax for creating a 5-tuple using the constructor −

Tuple<T1, T2, T3, T4, T5> tuple = new Tuple<T1, T2, T3, T4, T5>(item1, item2, item3, item4, item5);

You can also use the Tuple.Create() method for shorter syntax −

var tuple = Tuple.Create(item1, item2, item3, item4, item5);

Properties

A 5-tuple has five read-only properties to access its elements −

• Item1 − Gets the value of the first component.

• Item2 − Gets the value of the second component.

• Item3 − Gets the value of the third component.

• Item4 − Gets the value of the fourth component.

• Item5 − Gets the value of the fifth component.

Using Constructor to Create 5-Tuple

Example

using System;

public class Demo {
    public static void Main(string[] args) {
        Tuple<int, int, int, int, int> tuple = new Tuple<int, int, int, int, int>(120, 150, 270, 300, 600);
        Console.WriteLine("Value (Item1)= " + tuple.Item1);
        Console.WriteLine("Value (Item2)= " + tuple.Item2);
        Console.WriteLine("Value (Item3)= " + tuple.Item3);
        Console.WriteLine("Value (Item4)= " + tuple.Item4);
        Console.WriteLine("Value (Item5)= " + tuple.Item5);
        
        if (tuple.Item1 == 120) {
            Console.WriteLine("Exists: Tuple Item 1 = " + tuple.Item1);
        }
        if (tuple.Item3 == 270) {
            Console.WriteLine("Exists: Tuple Item 3 = " + tuple.Item3);
        }
        if (tuple.Item4 == 300) {
            Console.WriteLine("Exists: Tuple Item 4 = " + tuple.Item4);
        }
    }
}

The output of the above code is −

Value (Item1)= 120
Value (Item2)= 150
Value (Item3)= 270
Value (Item4)= 300
Value (Item5)= 600
Exists: Tuple Item 1 = 120
Exists: Tuple Item 3 = 270
Exists: Tuple Item 4 = 300

Using Mixed Data Types

Example

using System;

public class Demo {
    public static void Main(string[] args) {
        Tuple<string, int, string, int, int> tuple = new Tuple<string, int, string, int, int>("jack", 150, "pete", 300, 600);
        Console.WriteLine("Value (Item1)= " + tuple.Item1);
        Console.WriteLine("Value (Item2)= " + tuple.Item2);
        Console.WriteLine("Value (Item3)= " + tuple.Item3);
        Console.WriteLine("Value (Item4)= " + tuple.Item4);
        Console.WriteLine("Value (Item5)= " + tuple.Item5);
        
        if (tuple.Item1 == "jack") {
            Console.WriteLine("Exists: Tuple Item 1 = " + tuple.Item1);
        }
        if (tuple.Item3 == "pete") {
            Console.WriteLine("Exists: Tuple Item 3 = " + tuple.Item3);
        }
        if (tuple.Item4 == 300) {
            Console.WriteLine("Exists: Tuple Item 4 = " + tuple.Item4);
        }
    }
}

The output of the above code is −

Value (Item1)= jack
Value (Item2)= 150
Value (Item3)= pete
Value (Item4)= 300
Value (Item5)= 600
Exists: Tuple Item 1 = jack
Exists: Tuple Item 3 = pete
Exists: Tuple Item 4 = 300

Using Tuple.Create() Method

Example

using System;

public class Demo {
    public static void Main(string[] args) {
        var studentData = Tuple.Create("Alice", 21, "Computer Science", 3.8, 2025);
        Console.WriteLine("Student Name: " + studentData.Item1);
        Console.WriteLine("Age: " + studentData.Item2);
        Console.WriteLine("Major: " + studentData.Item3);
        Console.WriteLine("GPA: " + studentData.Item4);
        Console.WriteLine("Graduation Year: " + studentData.Item5);
        
        Console.WriteLine("\nComplete Student Record:");
        Console.WriteLine($"{studentData.Item1}, {studentData.Item2} years old, {studentData.Item3} major, GPA: {studentData.Item4}, Graduating: {studentData.Item5}");
    }
}

The output of the above code is −

Student Name: Alice
Age: 21
Major: Computer Science
GPA: 3.8
Graduation Year: 2025

Complete Student Record:
Alice, 21 years old, Computer Science major, GPA: 3.8, Graduating: 2025

Conclusion

The 5-tuple in C# provides a convenient way to group five related values of different types into a single object. You can create it using either the constructor or Tuple.Create() method, and access elements through Item1 through Item5 properties.
