Process.Close Methode

public:
 void Close();

public void Close();

member this.Close : unit -> unit

Public Sub Close ()

Beispiele

Im folgenden Beispiel wird eine Instanz von Editor gestartet. Anschließend wird die physische Speicherauslastung des zugeordneten Prozesses in 2-Sekunden-Intervallen für maximal 10 Sekunden abgerufen. Im Beispiel wird ermittelt, ob der Vorgang vor ablaufen 10 Sekunden abgelaufen ist. Im Beispiel wird der Prozess geschlossen, wenn er nach 10 Sekunden noch ausgeführt wird.

Hinweise

Die Close Methode bewirkt, dass der Prozess nicht mehr auf das Beenden wartet, wenn er wartet, das Prozesshandle schließt und prozessspezifische Eigenschaften löscht. Close schließt die Standardausgabe, Eingabe und Fehlerleseprogramme und -autoren nicht, falls extern darauf verwiesen wird.
