KnownFolder (Ersatz für Environment.GetFolderPath unter Vista)

Beschreibung:

Ab Vista/Windows Server 2008 werden die klassischen CSIDLs nicht mehr verwendet und man sollte die KNOWNFOLDER verwenden. Mit dieser kleinen Klasse können unter Vista/Win2008 alle bekannten KNOWNFOLDERs abgefragt werden.

Beispiel:

public void button1_Click(object sender, EventArgs e)
{
  try
  {
    // Der Pfad zum "Dokumente" Ordner des aktuellen Benutzers.
    Console.WriteLine(KnownFolder.GetKnownFolder(KnownFolders.Documents));
  }
  catch (InvalidOperationException)
  {
    Console.WriteLine("Nur ab Vista/Win2008 verfügbar");
  }
}
