ThreadInterruptedException-Klasse

Die Ausnahme, die ausgelöst wird, wenn ein Thread im Wartezustand unterbrochen wird.

Hinweise

Ein Thread befindet sich nach seiner Erstellung bis zu seiner Zerstörung in einem oder mehreren ThreadState-Zuständen. Wenn ein Thread sich im WaitSleepJoin-Zustand befindet, bewirkt der Aufruf von Interrupt, dass im Zielthread eine ThreadInterruptedException ausgelöst wird. Wenn der Thread sich nicht im WaitSleepJoin-Zustand befindet, wird die Ausnahme erst ausgelöst, wenn der Thread in diesen Zustand wechselt. Wenn der Thread nie blockiert wird, wird er möglicherweise ohne jede Unterbrechung vollständig ausgeführt.

ThreadInterruptedException verwendet HRESULT COR_E_ THREADINTERRUPTED mit dem Wert 0x80131519.

Eine Liste der anfänglichen Eigenschaftenwerte für eine Instanz von ThreadInterruptedException finden Sie unter ThreadInterruptedException-Konstruktoren.

Beispiel

Das folgende Codebeispiel veranschaulicht das Verhalten eines ausgeführten Threads, wenn dieser unterbrochen und anschließend gesperrt wird.
