How to create 3-ValueTuple in C#?
In C#, a triple or 3 value tuple is a value type tuple which holds three elements in it. You can create a triple value tuple using two different ways:
- Using ValueTuple <T1, T2, T3>(T1, T2, T3) Constructor
- Using Create <T1, T2, T3>(T1, T2, T3) Method
Using ValueTuple <T1, T2, T3>(T1, T2, T3) Constructor
You can create a triple value tuple by using ValueTuple <T1, T2, T3>(T1, T2, T3) constructor. It initializes a new instance of the ValueTuple <T1, T2, T3> 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);
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.
Example:
// C# program to create a triple // value tuple using value tuple constructor using System; class GFG { // Main method static public void Main() { // Creating a value tuple with three elements // Using ValueTuple<T1, T2, T3>(T1, T2, T3) constructor ValueTuple< string , string , string > MyTpl = new ValueTuple< string , string , string >( "Dog" , "Cat" , "Cow" ); Console.WriteLine( "Component 1: " + MyTpl.Item1); Console.WriteLine( "Component 2: " + MyTpl.Item2); Console.WriteLine( "Component 3: " + MyTpl.Item3); } } |
Component 1: Dog Component 2: Cat Component 3: Cow
Using Create <T1, T2, T3>(T1, T2, T3) Method
You can also create a triple value tuple or a value tuple which holds 3-elements with the help of Create <T1, T2, T3>(T1, T2, T3) 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> Create<T1, T2, T3> (T1 item1, T2 item2, T3 item3);
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.
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.
Returns: This method returns a value tuple with three elements.
Example:
// C# program to create a tuple value tuple // using Create<T1, T2, T3>(T1, T2, T3) method using System; class GFG { // Main method static public void Main() { // Creating a value tuple with three elements // Using Create<T1, T2, T3>(T1, T2, T3) method var MyTple = ValueTuple.Create(12, 34, 56); Console.WriteLine( "Component 1: " + MyTple.Item1); Console.WriteLine( "Component 2: " + MyTple.Item2); Console.WriteLine( "Component 3: " + MyTple.Item3); } } |
Component 1: 12 Component 2: 34 Component 3: 56
