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