How to create 3-Tuple or Triple Tuple in C#?

The Tuple<T1, T2, T3> class represents a 3-tuple, which is called triple. A tuple is a data structure that has a sequence of elements.

It is used in −

• Easier access to a data set.
• Easier manipulation of a data set.
• To represent a single set of data.
• To return multiple values from a method
• To pass multiple values to a method

Example

Let us now see an example to implement the 3-tuple in C# −

using System;
public class Demo {
   public static void Main(string[] args) {
      Tuple<int,string,string> tuple = new Tuple<int,string,string>(35, "steve", "katie");
      Console.WriteLine("Value (Item1)= " + tuple.Item1);
      Console.WriteLine("Value (Item2)= " + tuple.Item2);
      Console.WriteLine("Value (Item3)= " + tuple.Item3);
      if (tuple.Item1 == 35) {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item1);
      }
      if (tuple.Item2 == "jack") {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item2);
      }
      if (tuple.Item3 == "katie") {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item3);
      }
   }
}

Output

This will produce the following output −

Value (Item1)= 35
Value (Item2)= steve
Value (Item3)= katie
Exists: Tuple Value = 35
Exists: Tuple Value = katie

Example

Let us now see another example to implement the 3-tuple in C# −

using System;
public class Demo {
   public static void Main(string[] args) {
      Tuple<string,string,string> tuple = new Tuple<string,string,string>("nathan", "steve", "katie");
      Console.WriteLine("Value (Item1)= " + tuple.Item1);
      Console.WriteLine("Value (Item2)= " + tuple.Item2);
      Console.WriteLine("Value (Item3)= " + tuple.Item3);
      if (tuple.Item1 == "nathan") {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item1);
      }
      if (tuple.Item2 == "jack") {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item2);
      }
      if (tuple.Item3 == "katie") {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item3);
      }
   }
}

Output

This will produce the following output −

Value (Item1)= nathan
Value (Item2)= steve
Value (Item3)= katie
Exists: Tuple Value = nathan
Exists: Tuple Value = katie
