Tuples

Tuple is a fixed-size collection that can have elements of either same or different data types. Similar to arrays, a user must have to specify the size of a tuple at the time of declaration. Tuples are allowed to hold up from 1 to 8 elements and if there are more than 8 elements, then the 8th element can be defined as another tuple. Tuples can be specified as parameter or return type of a method.

 

C# program that uses 3 items in Tuple

using System;

class Program
{
    static void Main()
    {
 // Create three-item tuple.
 Tuple<int, string, bool> tuple =
     new Tuple<int, string, bool>(1, "cat", true);
 // Access tuple properties.
 if (tuple.Item1 == 1)
 {
     Console.WriteLine(tuple.Item1);
 }
 if (tuple.Item2 == "dog")
 {
     Console.WriteLine(tuple.Item2);
 }
 if (tuple.Item3)
 {
     Console.WriteLine(tuple.Item3);
 }
    }
}

Output
