C# | Tuple<T1,T2,T3,T4> Class

The Tuple<T1, T2, T3, T4> class is used to create a 4-tuple or quadruple. It represents a tuple which contains the four elements in it. You can instantiate a Tuple<T1, T2, T3, T4> object by calling either the Tuple<T1, T2, T3, T4>(T1, T2, T3, T4) constructor or by the static Tuple.Create method. You can retrieve the value of the tuple’s elements by using the read-only Item1, Item2, Item3, and Item4 instance property.

Important Points:

  • It implements IStructuralComparable, IStructuralEquatable, and IComparable interface.
  • It defined under System namespace.
  • It represent multiple data into a single data set.
  • It allows us to create, manipulate, and access data set.
  • It returns multiple values from a method without using out parameter.
  • It allows passing multiple values to a method with the help of single parameters.
  • It can also store duplicate elements.

Constructor

Constructor Description
Tuple<T1, T2, T3, T4>(T1, T2, T3, T4) Initializes a new instance of the Tuple<T1, T2, T3, T4> class.

Property

Property Description
Item1 Gets the value of the Tuple<T1, T2, T3, T4> object’s first component.
Item2 Gets the value of the current Tuple<T1, T2, T3, T4> object’s second component.
Item3 Gets the value of the current Tuple<T1, T2, T3, T4> object’s third component.
Item4 Gets the value of the current Tuple<T1, T2, T3, T4> object’s fourth component.

using System;
   
class GFG {
  
    // Main Method
    static public void Main ()
    {
        // Creating 4-Tuple
        // Using Tuple<T1, T2, T3, 
        // T4>(T1, T2, T3, T4) constructor
        Tuple<int, int, int, string>mytuple = new Tuple<int
                     int, int, string>(79, 34, 67, "Geeks");
           
        // Accessing the values
        Console.WriteLine("Value of the First Component: " + mytuple.Item1);
        Console.WriteLine("Value of the Second Component: " + mytuple.Item2);
        Console.WriteLine("Value of the Third Component: " + mytuple.Item3);
        Console.WriteLine("Value of the Fourth Component: " + mytuple.Item4);
  
    }
}

Output:

Value of the First Component: 79
Value of the Second Component: 34
Value of the Third Component: 67
Value of the Fourth Component: Geeks

Methods

Method Description
Equals(Object) Returns a value that indicates whether the current Tuple<T1, T2, T3, T4> object is equal to a specified object.
GetHashCode() Returns the hash code for the current Tuple<T1, T2, T3, T4> object.
GetType() Gets the Type of the current instance.
MemberwiseClone() Creates a shallow copy of the current Object.
ToString() Returns a string that represents the value of this Tuple<T1, T2, T3, T4> instance.

        }
  
        else 
        {
            Console.WriteLine("Tuple not Matched..");
        }
    }
