May 11, 2014

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 Example
{
   // Display the decimal.GetHashCode argument and the result array.
   public static void ShowDecimalGetHashCode(System.Windows.Controls.TextBlock outputBlock, decimal Argument)

      int hashCode = Argument.GetHashCode();

      outputBlock.Text += "{0,31}{1,14}  0x{1:X8}",
          Argument, hashCode + "\n";
   }
