Hinweise

Diese Eigenschaft gibt den Wert zurück, der durch Aufrufen WriteTimeout des zugrunde liegenden Datenstroms zurückgegeben wird. Bei Set-Vorgängen legt der angegebene Wert den WriteTimeout Wert für den zugrunde liegenden Stream fest.

Wenn der zugrunde liegende Datenstrom ein NetworkStreamist, WriteTimeout liegt in Millisekunden vor und ist standardmäßig auf Infinite festgelegt, sodass schreibvorgänge kein Timeout aufweisen.
