Decimal.GetHashCode Method in C# with Examples

Decimal.GetHashCode method is used to get the HashCode for the current Decimal 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:

Example 1:

// C# program to illustrate the
// Decimal.GetHashCode() Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {

        // Taking decimal variables
        // having fractional part
        Decimal dec1 = 214748.78549M;

        // Getting the hash code for Decimal
        // using GetHashCode() method
        int result = dec1.GetHashCode();

        // Display the time
        Console.WriteLine("HashCode for Decimal is: {0}",
                                                 result);
    }
}

Output:

HashCode for Decimal is: 161795526

Example 2:

// C# program to illustrate the
// Decimal.GetHashCode() Method
using System;

class GFG {

    // Main Method
    public static void Main()
    {
        // using result() Method
        result(Decimal.MinValue);
        result(Decimal.MaxValue);
    }

    // result() method
    public static void result(decimal val)
    {

        // using GetHashCode() method
        int code = val.GetHashCode();

        // Display the hashcode
        Console.WriteLine("HashCode for {0} is {1}",
                                         val, code);
    }
}

Output:

HashCode for -79228162514264337593543950335 is -974127104
HashCode for 79228162514264337593543950335 is 1173356544
