How to create 5-ValueTuple in C#?
In C#, a 5-ValueTuple or quintuple is a value type tuple which contains five elements. You can create a 5-ValueTuple using two different ways:
- Using ValueTuple <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) Constructor
- Using Create <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) Method
Using ValueTuple <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) Constructor
You can create a quintuple value tuple by using ValueTuple <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) constructor. It initializes a new instance of the ValueTuple <T1, T2, T3, T4, T5> 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);
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.
Example:
// C# program to create a quintuple // value tuple using value tuple constructor using System; class GFG { // Main method static public void Main() { // Creating a value tuple with five elements // Using ValueTuple<T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) constructor ValueTuple< string , string , string , string , string > MyTpl = new ValueTuple< string , string , string , string , string >( "Dog" , "Cat" , "Cow" , "Pig" , "Hen" ); 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); } } |
Component 1: Dog Component 2: Cat Component 3: Cow Component 4: Pig Component 5: Hen
Using Create <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) Method
You can also create a quintuple value tuple or a value tuple which holds 5-elements with the help of Create <T1, T2, T3, T4, T5>(T1, T2, T3, T4, T5) 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> Create<T1, T2, T3, T4, T5> (T1 item1, T2 item2, T3 item3, T4 item4, T5 item5);
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.
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.
Returns: This method returns a value tuple with five elements.
Example:
// C# program to create a quintuple value tuple // using Create<T1, T2, T3, T4, T5>(T1, T2, T3, // T4, T5) method using System; class GFG { // Main method static public void Main() { // Creating a value tuple with five elements // Using Create<T1, T2, T3, T4, T5>(T1, T2, // T3, T4, T5) method var MyTple = ValueTuple.Create(12, 34, 56, 45, 67); 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); } } |
Component 1: 12 Component 2: 34 Component 3: 56 Component 4: 45 Component 5: 67
