Tuple class in C#

Tuple class represents a 4-tuple, called a quad. A tuple is a data structure with a sequence of elements.

It is used to -

• make it easier to access the dataset.
• Manipulate data sets more easily.
• represents a single data set.
• Returning multiple values ​​from a method
• Passing multiple values ​​to a method

It has four properties -

• Item1 - Gets the value of the current Tuple first component of the object.

• Item2 - Gets the second component of the current Tuple's value object.

• Item3 - Gets the value of the third component of the current Tuple object.

• Item4 - Gets the value of the fourth component of the current Tuple object.

Example

Now let's see an example of implementing a 4-tuple in C# -

using System;
public class Demo {
   public static void Main(string[] args) {
      Tuple<string,string,string,string> tuple = new Tuple<string,string,string,string>("nathan", "steve", "katie", "tim");
      Console.WriteLine("Value (Item1)= " + tuple.Item1);
      Console.WriteLine("Value (Item2)= " + tuple.Item2);
      Console.WriteLine("Value (Item3)= " + tuple.Item3);
      Console.WriteLine("Value (Item4)= " + tuple.Item4);
      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);
      }
      if (tuple.Item4 == "tom") {
         Console.WriteLine("Exists: Tuple Value = " +tuple.Item4);
      }
   }
}

Output

This will produce the following output-

Value (Item1)= nathan
Value (Item2)= steve
Value (Item3)= katie Value
Value (Item4)= tom
Exists: Tuple Value = nathan
Exists: Tuple Value = katie

Example

Now let’s see another one in C# Example of implementing a 4-tuple -

using System;
public class Demo {
   public static void Main(string[] args) {
      Tuple<int,int,int,int> tuple = new Tuple<int,int,int,int>(100, 150, 300, 450);
      Console.WriteLine("Value (Item1)= " + tuple.Item1);
      Console.WriteLine("Value (Item2)= " + tuple.Item2);
      Console.WriteLine("Value (Item3)= " + tuple.Item3);
      Console.WriteLine("Value (Item4)= " + tuple.Item4);
      if (tuple.Item1 == 100) {
         Console.WriteLine("Exists: Tuple Item 1 = " +tuple.Item1);
      }
      if (tuple.Item2 == 250) {
         Console.WriteLine("Exists: Tuple Item 2 = " +tuple.Item2);
      }
      if (tuple.Item3 == 270) {
         Console.WriteLine("Exists: Tuple Item 3 = " +tuple.Item3);
      }
      if (tuple.Item4 == 300) {
         Console.WriteLine("Exists: Tuple Item 4 = " +tuple.Item4);
      }
   }
}

Output

This will produce the following output-

Value (Item1)= 100
Value (Item2)= 150
Value (Item3)= 300
Value (Item4)= 450
Exists: Tuple Item 1 = 100
