Getting the hash code of the ValueTuple in C#

ValueTuple.GetHashCode Method is used to get the HashCode of the current ValueTuple instance. It is provided by the ValueTuple struct.

Syntax:

public override int GetHashCode ();

Returns: The return type of this method is System.Int32 and it always returns zero.



Example:

        // Creating a value tuple with one element
        var MyTple2 = (23);
        Console.WriteLine("HashCode of a value tuple "+
            "with one element: " + MyTple2.GetHashCode());
  
        // Creating a value tuple with two elements
        var MyTple3 = (56, 45);
        Console.WriteLine("HashCode of a value tuple "+
           "with two elements: " + MyTple3.GetHashCode());
  
        // Creating a value tuple with three elements
        var MyTple4 = (67, 78, 89);
        Console.WriteLine("HashCode of a value tuple with "+
                "three elements: " + MyTple4.GetHashCode());
  
        // Creating a value tuple with four elements
        var MyTple5 = (09, 23, 12, 1);
        Console.WriteLine("HashCode of a value tuple with "+
                 "four elements: " + MyTple5.GetHashCode());
  
        // Creating a value tuple with five elements
        var MyTple6 = (65, 87, 98, 23, 45);
        Console.WriteLine("HashCode of a value tuple with"+

        // Creating a value tuple with six elements

                " six elements: " + MyTple7.GetHashCode());
  
        // Creating a value tuple with seven elements
        var MyTple8 = (32, 45, 96, 78, 35, 33, 44);
        Console.WriteLine("HashCode of a value tuple with"+
              " seven elements: " + MyTple8.GetHashCode());
    }
}
