Actualización: noviembre 2007

Obtiene un valor que contiene los estados del subproceso actual.

Espacio de nombres:  System.Threading
Ensamblado:  mscorlib (en mscorlib.dll)

public ThreadState ThreadState { get; }
/** @property */
public ThreadState get_ThreadState()

public function get ThreadState () : ThreadState

Valor de propiedad

Tipo: System.Threading.ThreadState
Uno de los valores de ThreadState que indican el estado del subproceso actual. El valor inicial es Unstarted.

La propiedad ThreadState proporciona información más específica que la propiedad IsAlive.

El estado de los subprocesos sólo es de interés en escenarios de depuración. El código nunca debe utilizar el estado de los subprocesos para sincronizar las actividades de los subprocesos.

En el ejemplo de código siguiente se muestra cómo se obtiene acceso al ThreadState de un subproceso.

using System;
using System.Threading;

class ApartmentTest
{
    static void Main()
    {
        Thread newThread = 
            new Thread(new ThreadStart(ThreadMethod));
        newThread.SetApartmentState(ApartmentState.MTA);

        // The following line is ignored since 
        // ApartmentState can only be set once.
        newThread.SetApartmentState(ApartmentState.STA);

        Console.WriteLine("ThreadState: {0}, ApartmentState: {1}", 
            newThread.ThreadState, newThread.ApartmentState);

        newThread.Start();

        // Wait for newThread to start and go to sleep.
        Thread.Sleep(300);
        try
        {
            // This causes an exception since newThread is sleeping.
            newThread.SetApartmentState(ApartmentState.STA);
        }
        catch(ThreadStateException stateException)
        {
            Console.WriteLine("\n{0} caught:\n" +
                "Thread is not in the Unstarted or Running state.", 
                stateException.GetType().Name);
            Console.WriteLine("ThreadState: {0}, ApartmentState: {1}",
                newThread.ThreadState, newThread.GetApartmentState());
        }
    }
