ThreadStateException ThreadStateException ThreadStateException ThreadStateException Class

定义

Thread 处于对方法调用无效的 ThreadState 时引发的异常。The exception that is thrown when a Thread is in an invalid ThreadState for the method call.

[System.Runtime.InteropServices.ComVisible(true)]
[System.Serializable]
public class ThreadStateException : SystemException

示例

下面的示例演示了导致系统引发的ThreadStateException错误。The following example demonstrates an error that causes the system to throw a ThreadStateException.

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 'ThreadWork

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 'ThreadStateTest

此代码生成以下输出:This code produces the following output:

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

注解

一旦创建了一个线程, 该线程将处于至少一种ThreadState状态直到终止。Once a thread is created, it is in at least one of the ThreadState states until it terminates. ThreadStateException由于线程的当前状态而无法执行所请求操作的方法引发。ThreadStateException is thrown by methods that cannot perform the requested operation due to the current state of a thread. 例如, 尝试通过在已终止的线程上调用Start来重新启动中止的ThreadStateException线程会引发。For example, trying to restart an aborted thread by calling Start on a thread that has terminated throws a ThreadStateException.

ThreadStateException使用 COR_E_THREADSTATE 值为0x80131520 的 HRESULT。ThreadStateException uses the HRESULT COR_E_THREADSTATE, which has the value 0x80131520.
