아파트 상태를 나타내는 ApartmentState 값을 반환합니다.

public:
 System::Threading::ApartmentState GetApartmentState();

public System.Threading.ApartmentState GetApartmentState ();

member this.GetApartmentState : unit -> System.Threading.ApartmentState

Public Function GetApartmentState () As ApartmentState

반환

ApartmentState

관리되는 스레드의 아파트 상태를 나타내는 ApartmentState 값 중 하나입니다. 기본값은 Unknown입니다.

예제

다음 코드 예제에서는 GetApartmentState , 및 메서드를 보여 줍니다 SetApartmentState TrySetApartmentState . 코드 예제는 스레드를 만듭니다. 스레드가 시작 되기 전에는 GetApartmentState 초기 상태를 표시 하 ApartmentState.Unknown 고 SetApartmentState 상태를로 변경 ApartmentState.STA 합니다. TrySetApartmentState false ApartmentState.MTA 아파트 상태가 이미 설정 되었기 때문에 메서드는 상태를로 변경 하려고 할 때를 반환 합니다. 로 동일한 작업을 시도한 경우 SetApartmentState 이 throw 됩니다 InvalidOperationException .

스레드가 시작 된 후에는 TrySetApartmentState 메서드가 다시 사용 됩니다. ThreadStateException스레드가 이미 시작 되었기 때문에이 시간이 throw 됩니다.
