The Tuple class represents a 1-tuple, which is called singleton. A tuple is a data structure that has a sequence of elements.ExampleLet us now see an example to implement the 1-tuple in C# −using System; public class Demo {    public static void Main(string[] args) {       Tuple tuple = new Tuple(100);       Console.WriteLine("Value = " + tuple.Item1);       if (tuple.Item1 == 150) {          Console.WriteLine(tuple.Item1);       }       if (tuple.Item1 == 100) {          Console.WriteLine(tuple.Item1);       }    } }OutputThis will ...
