Thread.IsThreadPoolThread Propiedad

Definición

Obtiene un valor que indica si un subproceso pertenece al grupo de subprocesos administrados o no.Gets a value indicating whether or not a thread belongs to the managed thread pool.

public:
 property bool IsThreadPoolThread { bool get(); };
public bool IsThreadPoolThread { get; }
member this.IsThreadPoolThread : bool
Public ReadOnly Property IsThreadPoolThread As Boolean

Valor de propiedad

true si el subproceso pertenece al grupo de subprocesos administrados; en caso contrario, false.true if this thread belongs to the managed thread pool; otherwise, false.

Ejemplos

En el ejemplo de código siguiente se muestra cómo determinar si un subproceso procede del grupo de subprocesos.The following code example shows how to determine whether a thread is from the thread pool.

using namespace System;
using namespace System::Threading;
ref class IsThreadPool
{
public:

   static void ThreadMethod()
   {
      Console::WriteLine( "ThreadOne, executing ThreadMethod, "
      "is {0}from the thread pool.", Thread::CurrentThread->IsThreadPoolThread ? (String^)"" : "not " );
   }


   static void WorkMethod( Object^ stateInfo )
   {
      Console::WriteLine( "ThreadTwo, executing WorkMethod, "
      "is {0}from the thread pool.", Thread::CurrentThread->IsThreadPoolThread ? (String^)"" : "not " );
      
      // Signal that this thread is finished.
      dynamic_cast<AutoResetEvent^>(stateInfo)->Set();
   }

};

int main()
{
   AutoResetEvent^ autoEvent = gcnew AutoResetEvent( false );
   Thread^ regularThread = gcnew Thread( gcnew ThreadStart( &IsThreadPool::ThreadMethod ) );
   regularThread->Start();
   ThreadPool::QueueUserWorkItem( gcnew WaitCallback( &IsThreadPool::WorkMethod ), autoEvent );
   
   // Wait for foreground thread to end.
   regularThread->Join();
   
   // Wait for background thread to end.
   autoEvent->WaitOne();
}

using System;
using System.Threading;

class IsThreadPool
{
    static void Main()
    {
        AutoResetEvent autoEvent = new AutoResetEvent(false);

        Thread regularThread = 
            new Thread(new ThreadStart(ThreadMethod));
        regularThread.Start();
        ThreadPool.QueueUserWorkItem(new WaitCallback(WorkMethod), 
            autoEvent);

        // Wait for foreground thread to end.
        regularThread.Join();

        // Wait for background thread to end.
        autoEvent.WaitOne();
    }

    static void ThreadMethod()
    {
        Console.WriteLine("ThreadOne, executing ThreadMethod, " +
            "is {0}from the thread pool.", 
            Thread.CurrentThread.IsThreadPoolThread ? "" : "not ");
    }

    static void WorkMethod(object stateInfo)
    {
        Console.WriteLine("ThreadTwo, executing WorkMethod, " +
            "is {0}from the thread pool.", 
            Thread.CurrentThread.IsThreadPoolThread ? "" : "not ");

        // Signal that this thread is finished.
        ((AutoResetEvent)stateInfo).Set();
    }
}

Option Strict
