Thread.IsThreadPoolThread Property

Gets a value indicating whether or not a thread belongs to the managed thread pool.

Namespace: System.Threading
Assembly: mscorlib (in mscorlib.dll)

public:
property bool IsThreadPoolThread {
	bool get ();
}
/** @property */
public boolean get_IsThreadPoolThread ()

public function get IsThreadPoolThread () : boolean

Property Value

true if this thread belongs to the managed thread pool; otherwise, false.

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();
}


import System.*;
import System.Threading.*;
import System.Threading.Thread;

class IsThreadPool
{
    public static void main(String[] args)
    {
        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();
    } //main

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

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

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