Een 32-bits ondertekende hashcode voor gehele getallen.
Voorbeelden
In het volgende voorbeeld worden de hash-codes van verschillende TimeSpan objecten gegenereerd met behulp van de GetHashCode methode.
// Example for the TimeSpan.GetHashCode( ) method.
using System;
class GetHashCode
{
static void DisplayHashCode( TimeSpan interval )
{
// Create a hash code and a string representation of
// the TimeSpan parameter.
string timeInterval = interval.ToString( );
int hashCode = interval.GetHashCode( );
// Pad the end of the TimeSpan string with spaces if it
// does not contain milliseconds.
int pIndex = timeInterval.IndexOf( ':' );
pIndex = timeInterval.IndexOf( '.', pIndex );
if( pIndex < 0 ) timeInterval += " ";
Console.WriteLine( "{0,22} 0x{1:X8}, {1}",
timeInterval, hashCode );
}
static void Main( )
{
Console.WriteLine(
"This example of TimeSpan.GetHashCode( ) generates " +
"the following \noutput, which displays " +
"the hash codes of representative TimeSpan \n" +
"objects in hexadecimal and decimal formats.\n" );
Console.WriteLine( "{0,22} {1,10}",
"TimeSpan ", "Hash Code" );
Console.WriteLine( "{0,22} {1,10}",
"-------- ", "---------" );

Opmerkingen
Twee TimeSpan objecten hebben mogelijk dezelfde hashcode, ook al vertegenwoordigen ze verschillende tijdwaarden.
