How to create 7-ValueTuple in C#?

In C#, a 7-ValueTuple is a value type tuple which contains seven elements and it is also known as septuple. You can create a 7-ValueTuple using two different ways:

Using ValueTuple <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) Constructor
Using Create <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) Method

Using ValueTuple <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) Constructor

You can create a 7-ValueTuple by using ValueTuple <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) constructor. It initializes a new instance of the ValueTuple <T1, T2, T3, T4, T5, T6, T7> struct. But when you create a value tuple using this constructor, then you have to specify the type of the element stored in the value tuple.

Syntax:

public ValueTuple (T1 item1, T2 item2, T3 item3, T4 item4, T5 item5, T6 item6, T7 item7);

Parameters:

item1: It is the value of the first value tuple component.
item2: It is the value of the second value tuple component.
item3: It is the value of the third value tuple component.
item4: It is the value of the fourth value tuple component.
item5: It is the value of the fifth value tuple component.
item6: It is the value of the sixth value tuple component.
item7: It is the value of the seventh value tuple component.

Example:

// C# program to create a 7-ValueTuple 
// using value tuple constructor 

using System; 

class GFG { 

    // Main method 

    static public void Main() 

    { 

        // Creating a value tuple with seven elements 

        // Using ValueTuple<T1, T2, T3, T4, T5, T6, 

        // T7>(T1, T2, T3, T4, T5, T6, T7) constructor 

        ValueTuple<string, string, string, string, string, string, 

            string> MyTpl = new ValueTuple<string, string, string,  

              string, string, string, string>("Dog", "Cat", "Cow", 

                                    "Pig", "Hen", "Bird", "Fish"); 

        Console.WriteLine("Component 1: " + MyTpl.Item1); 

        Console.WriteLine("Component 2: " + MyTpl.Item2); 

        Console.WriteLine("Component 3: " + MyTpl.Item3); 

        Console.WriteLine("Component 4: " + MyTpl.Item4); 

        Console.WriteLine("Component 5: " + MyTpl.Item5); 

        Console.WriteLine("Component 6: " + MyTpl.Item6); 

        Console.WriteLine("Component 7: " + MyTpl.Item7); 

    } 
}

Output:

Component 1: Dog
Component 2: Cat
Component 3: Cow
Component 4: Pig
Component 5: Hen
Component 6: Bird
Component 7: Fish

Using Create <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) Method

You can also create a 7-ValueTuple or a value tuple which holds 7-elements with the help of Create <T1, T2, T3, T4, T5, T6, T7>(T1, T2, T3, T4, T5, T6, T7) method. When you use this method, then there is no need to specify the type of the elements stored in the value tuple.

Syntax:

public static ValueTuple<T1, T2, T3, T4, T5, T6, T7> Create<T1, T2, T3, T4, T5, T6, T7> (T1 item1, T2 item2, T3 item3, T4 item4, T5 item5, T6 item6, T7 item7);

Type Parameters:

T1: It is the type of the value tuple’s first component.
T2: It is the type of the value tuple’s second component.
T3: It is the type of the value tuple’s third component.
T4: It is the type of the value tuple’s fourth component.
T5: It is the type of the value tuple’s fifth component.
T6: It is the type of the value tuple’s sixth component.
T7: It is the type of the value tuple’s seventh component.

Parameters:

item1: It is the value of the value tuple’s first component.
item2: It is the value of the value tuple’s second component.
item3: It is the value of the value tuple’s third component.
item4: It is the value of the value tuple’s fourth component.
item5: It is the value of the value tuple’s fifth component.
item6: It is the value of the value tuple’s sixth component.
item7: It is the value of the value tuple’s seventh component.

Returns: This method returns a value tuple with seven elements.

Example:

// C# program to create a 7-ValueTuple 
// using Create<T1, T2, T3, T4, T5, T6, 
// T7>(T1, T2, T3, T4, T5, T6, T7) Method 

using System; 

class GFG { 

    // Main method 

    static public void Main() 

    { 

        // Creating a value tuple with seven elements 

        // Using Create<T1, T2, T3, T4, T5, T6,  

        // T7>(T1, T2, T3, T4, T5, T6, T7) method 

        var MyTple = ValueTuple.Create(12, 34, 56, 45, 

                                          67, 89, 78); 

        Console.WriteLine("Component 1: " + MyTple.Item1); 

        Console.WriteLine("Component 2: " + MyTple.Item2); 

        Console.WriteLine("Component 3: " + MyTple.Item3); 

        Console.WriteLine("Component 4: " + MyTple.Item4); 

        Console.WriteLine("Component 5: " + MyTple.Item5); 

        Console.WriteLine("Component 6: " + MyTple.Item6); 

        Console.WriteLine("Component 7: " + MyTple.Item7); 

    } 
}

Output:

Component 1: 12
Component 2: 34
Component 3: 56
Component 4: 45
Component 5: 67
Component 6: 89
Component 7: 78
