Decimal.GetHashCode Method

Returns the hash code for this instance.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public override int GetHashCode()

Return Value

Type: System.Int32
A 32-bit signed integer hash code.

The following code example uses the GetHashCode method to return the hash codes of several Decimal values.


// Example of the decimal.GetHashCode method. 
using System;

class DecimalGetHashCodeDemo
{
    // Display the decimal.GetHashCode argument and the result array.
    public static void ShowDecimalGetHashCode( decimal Argument )
    {
        int hashCode = Argument.GetHashCode( );

        Console.WriteLine( "{0,31}{1,14}  0x{1:X8}", 
            Argument, hashCode );
    }

    public static void Main( )
    {
        Console.WriteLine( "This example of the " +
            "decimal.GetHashCode( ) method generates \nthe " +
            "following output. It displays the hash code of the \n" +
            "decimal argument in decimal and hexadecimal.\n" );
        Console.WriteLine( "{0,31}{1,14}", "Argument", "Hash Code" );
        Console.WriteLine( "{0,31}{1,14}", "--------", "---------" );

        // Generate hash codes for decimal objects.
        ShowDecimalGetHashCode( 0M );
        ShowDecimalGetHashCode( 1M );
        ShowDecimalGetHashCode( 1.0000000000000000000000000000M );
        ShowDecimalGetHashCode( 100000000000000M );
