Int32.GetHashCode method is used to get the HashCode for the current Int32 instance.

Syntax: public override int GetHashCode ();

Return Value: This method returns a 32-bit signed integer hash code.



Below programs illustrate the use of the above discussed-method:

    // Main Method
    public static void Main()
    {
  
        // Taking Int32 variable
        int val = 32523;
  
        // Getting the hash code for Int32
        // using GetHashCode() method
        int result = val.GetHashCode();
  
        // Display the hashcode
        Console.WriteLine("HashCode for Int32 is: {0}",
                                               result);
    }
}
