Im folgenden Codebeispiel wird veranschaulicht, wie der Apartmentstatus eines Threads festgelegt wird.

using namespace System;
using namespace System::Threading;

   {
      Thread::Sleep( 1000 );

   Thread^ newThread = gcnew Thread( gcnew ThreadStart( &ApartmentTest::ThreadMethod ) );
   newThread->SetApartmentState(ApartmentState::MTA);
   
   Console::WriteLine( "ThreadState: {0}, ApartmentState: {1}", newThread->ThreadState.ToString(), newThread->GetApartmentState().ToString() );
   newThread->Start();
   
   // Wait for newThread to start and go to sleep.
   Thread::Sleep( 300 );
   try
   {
      
      // This causes an exception since newThread is sleeping.
      newThread->SetApartmentState(ApartmentState::STA);
   }
   catch ( ThreadStateException^ stateException ) 
   {

Hinweise

Die ApartmentState-Eigenschaft ist veraltet. Die nicht veralteten Alternativen sind die GetApartmentState Methode zum Abrufen des Wohnungszustands und die SetApartmentState Methode zum Festlegen des Wohnungszustands.

In .NET Framework Versionen 1.0 und 1.1 markiert die ApartmentState -Eigenschaft einen Thread, um anzugeben, dass er in einem Singlethread- oder Multithread-Apartment ausgeführt wird. Diese Eigenschaft kann festgelegt werden, wenn sich der Thread im UnstartedRunning Oder-Zustand befindet. Sie kann jedoch nur einmal für einen Thread festgelegt werden. Wenn die -Eigenschaft nicht festgelegt wurde, wird zurückgegeben Unknown.

Ein Versuch, mit der ApartmentState -Eigenschaft den Apartmentstatus eines Threads festzulegen, dessen Apartmentstatus bereits festgelegt wurde, wird ignoriert. In diesem Fall löst die SetApartmentState -Methode jedoch ein aus InvalidOperationException .

In .NET Framework Version 2.0 können Sie das COM-Threadingmodell für eine C++-Anwendung mithilfe der Linkeroption /CLRTHREADATTRIBUTE (Set CLR Thread Attribute) angeben.
