Örnekler

Aşağıdaki örnekte, sistemin bir oluşturmasına neden olan bir ThreadStateExceptionhata gösterilmektedir.

using namespace System;
using namespace System::Threading;
ref class ThreadWork
{
public:
   static void DoWork()
   {
      Console::WriteLine( "Working thread..." );
   }

};

int main()
{
   ThreadStart^ myThreadDelegate = gcnew ThreadStart( ThreadWork::DoWork );
   Thread^ myThread = gcnew Thread( myThreadDelegate );
   myThread->Start();
   Thread::Sleep( 0 );
   Console::WriteLine( "In main. Attempting to restart myThread." );
   try
   {
      myThread->Start();
   }
   catch ( ThreadStateException^ e ) 
   {
      Console::WriteLine( "Caught: {0}", e->Message );
   }

}

using System;
using System.Threading;

public class ThreadWork
{
   public static void DoWork()
   {
      Console.WriteLine("Working thread...");
   }
}

class ThreadStateTest
{
   public static void Main()
   {
      ThreadStart myThreadDelegate = new ThreadStart(ThreadWork.DoWork);
      Thread myThread = new Thread(myThreadDelegate);
      myThread.Start();
      Thread.Sleep(0);
      Console.WriteLine("In main. Attempting to restart myThread.");
      try
      {
         myThread.Start();
      }
      catch (ThreadStateException e)
      {
         Console.WriteLine("Caught: {0}", e.Message);
      }
   }
}

Imports System.Threading

Public Class ThreadWork
   
   Public Shared Sub DoWork()
      Console.WriteLine("Working thread...")
   End Sub
End Class

Class ThreadStateTest
   
   Public Shared Sub Main()
      Dim myThreadDelegate As New ThreadStart(AddressOf ThreadWork.DoWork)
      Dim myThread As New Thread(myThreadDelegate)
      myThread.Start()
      Thread.Sleep(0)
      Console.WriteLine("In main. Attempting to restart myThread.")
      Try
         myThread.Start()
      Catch e As ThreadStateException
         Console.WriteLine("Caught: {0}", e.Message)
      End Try
   End Sub
End Class

Bu kod şu çıkışı oluşturur:

In main. Attempting to restart myThread.  
    Working thread...  
    Caught: Thread is running or terminated. Cannot restart.  

Açıklamalar

Bir iş parçacığı oluşturulduktan sonra, sonlandırılana ThreadState kadar en az bir durumda olur. ThreadStateException , bir iş parçacığının geçerli durumu nedeniyle istenen işlemi gerçekleştiremeyen yöntemler tarafından oluşturulur. Örneğin, sonlandırılan bir iş parçacığında çağrısı Start yaparak durdurulan bir iş parçacığını yeniden başlatmaya çalışmak bir ThreadStateExceptionoluşturur.

ThreadStateException değeri 0x80131520 olan HRESULT COR_E_THREADSTATE kullanır.

örneğinin ilk özellik değerlerinin ThreadStateExceptionlistesi için oluşturuculara ThreadStateException bakın.
