定義

命名空間:

組件:

System.Threading.Thread.dll

Source:

ThreadAbortException.cs

取得物件，其中包含有關執行緒中止之特定應用程式的資訊。

public:
 property System::Object ^ ExceptionState { System::Object ^ get(); };

public object? ExceptionState { get; }

member this.ExceptionState : obj

Public ReadOnly Property ExceptionState As Object

屬性值

Object

包含特定應用程式資訊的物件。

範例

下列程式碼範例示範如何將資訊傳遞至正在中止的執行緒。

using namespace System;
using namespace System::Threading;
ref class Test
{
private:
   Test(){}


public:
   static void TestMethod()
   {
      try
      {
         while ( true )
         {
            Console::WriteLine( "New thread running." );
            Thread::Sleep( 1000 );
         }
      }
      catch ( ThreadAbortException^ abortException ) 
      {
         Console::WriteLine( dynamic_cast<String^>(abortException->ExceptionState) );
      }

   }

};

int main()
{
   Thread^ newThread = gcnew Thread( gcnew ThreadStart( &Test::TestMethod ) );
   newThread->Start();
   Thread::Sleep( 1000 );
   
   // Abort newThread.
   Console::WriteLine( "Main aborting new thread." );
   newThread->Abort( "Information from main." );
   
   // Wait for the thread to terminate.
   newThread->Join();
   Console::WriteLine( "New thread terminated - main exiting." );
}

using System;
using System.Threading;

            Console.WriteLine((string)abortException.ExceptionState);
        }
    }
}

        Console.WriteLine("Main aborting new thread.")
        newThread.Abort("Information from Main.")

        ' Wait for the thread to terminate.
        newThread.Join()
        Console.WriteLine("New thread terminated - Main exiting.")
    End Sub

    Shared Sub TestMethod()
        Try
            While True

備註

這個屬性所傳回的物件是透過 stateInfo 方法的 Abort 參數來指定。 此物件的確切內容和使用方式是定義應用程式;它通常用來傳達對中止之執行緒有意義的資訊。
