How to create 8-ValueTuple in C#?

  • Last Updated : 23 Jul, 2019

In C#, an 8-ValueTuple is a value type tuple which contains eight elements and it is also known as octuple. You can create an 8-ValueTuple using two different ways:

  1. Using ValueTuple<T1, T2, T3, T4, T5, T6, T7, TRest<(T1, T2, T3, T4, T5, T6, T7, TRest) Constructor
  2. Using Create<T1, T2, T3, T4, T5, T6, T7, T8<(T1, T2, T3, T4, T5, T6, T7, T8) Method

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

You can create an 8-ValueTuple by using ValueTuple<T1, T2, T3, T4, T5, T6, T7, TRest<(T1, T2, T3, T4, T5, T6, T7, TRest) constructor. It initializes a new instance of the ValueTuple<T1, T2, T3, T4, T5, T6, T7, TRest< 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. Using this constructor, you can also create a value tuple which contains nine or more than nine elements by using the rest parameter. With the help of the rest parameter, you can create n-nested value tuples.

Syntax:

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

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.
  • rest: It is the instance of any value tuple type that contains the values of the value’s tuple’s remaining elements.

Exception: This will give ArgumentException if the rest is not a generic value tuple type.

Example:




// C# program to create a 8-ValueTuple
// using ValueTuple constructor
using System;
  
class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Creating a value tuple with eight elements
        // Using ValueTuple<T1, T2, T3, T4, T5, T6,
        // T7, TRest>(T1, T2, T3, T4, T5, T6, T7, 
        // TRest rest) constructor
        ValueTuple<string, string, string, string, string, string,
          string, ValueTuple<string>> MyTpl = new ValueTuple<string,
                     string, string, string, string, string, string
                     ValueTuple<string>>("Rohan", "Sumit", "Soniya"
                               "Shivam", "Raksha", "Purvi", "Mohan",
                                   new ValueTuple<string>("Nayan"));
  
        Console.WriteLine("Student 1: " + MyTpl.Item1);
        Console.WriteLine("Student 2: " + MyTpl.Item2);
        Console.WriteLine("Student 3: " + MyTpl.Item3);
        Console.WriteLine("Student 4: " + MyTpl.Item4);
        Console.WriteLine("Student 5: " + MyTpl.Item5);
        Console.WriteLine("Student 6: " + MyTpl.Item6);
        Console.WriteLine("Student 7: " + MyTpl.Item7);
        Console.WriteLine("Student 8: " + MyTpl.Rest);
    }
}
Output:
Student 1: Rohan
Student 2: Sumit
Student 3: Soniya
Student 4: Shivam
Student 5: Raksha
Student 6: Purvi
Student 7: Mohan
Student 8: (Nayan)

Using Create<T1, T2, T3, T4, T5, T6, T7, T8<(T1, T2, T3, T4, T5, T6, T7, T8) Method

You can also create an 8-ValueTuple or a value tuple which holds 8-elements with the help of Create<T1, T2, T3, T4, T5, T6, T7, T8<(T1, T2, T3, T4, T5, T6, T7, T8) method. When you use this method, then there is no need to specify the type of elements stored in the value tuple.

Syntax:

public static ValueTuple <T1, T2, T3, T4, T5, T6, T7, ValueTuple<T8>> Create< T1, T2, T3, T4, T5, T6, T7, T8> (T1 item1, T2 item2, T3 item3, T4 item4, T5 item5, T6 item6, T7 item7, T8 item8);

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.
  • T8: It is the type of the value tuple’s eighth 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.
  • item8: It is the value of the value tuple’s eighth component.

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

Example:




// C# program to create a 8-ValueTuple
// using Create Method
using System;
  
class GFG {
  
    // Main method
    static public void Main()
    {
  
        // Creating a value tuple with the 
        // eight elements using Create method
        var MyTple = ValueTuple.Create(45.67, 67.78, 56.8, 567.5,
                                       23.4, 56.7, 12.34, 35.56);
  
        // Display the components of the value tuple
        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);
        Console.WriteLine("Component 8: " + MyTple.Item7);
    }
}
Output:
Component 1: 45.67
Component 2: 67.78
Component 3: 56.8
Component 4: 567.5
Component 5: 23.4
Component 6: 56.7
Component 7: 12.34
Component 8: 12.34
