Comentarios

Joines un método de sincronización que bloquea el subproceso que realiza la llamada (es decir, el subproceso que llama al Join método) hasta que se completa el subproceso cuyo método se llama.Join is a synchronization method that blocks the calling thread (that is, the thread that calls the method) until the thread whose Join method is called has completed. Utilice este método para asegurarse de que un subproceso ha finalizado.Use this method to ensure that a thread has been terminated. El autor de la llamada se bloqueará indefinidamente si el subproceso no finaliza.The caller will block indefinitely if the thread does not terminate. En el ejemplo siguiente, el Thread1 subproceso llama Join() al método Thread2de, que Thread1 hace que se Thread2 bloquee hasta que se haya completado.In the following example, the Thread1 thread calls the Join() method of Thread2, which causes Thread1 to block until Thread2 has completed.

using System;
using System.Threading;

public class Example
{
   static Thread thread1, thread2;
   
   public static void Main()
   {
      thread1 = new Thread(ThreadProc);
      thread1.Name = "Thread1";
      thread1.Start();
      
      thread2 = new Thread(ThreadProc);
      thread2.Name = "Thread2";
      thread2.Start();   
   }

   private static void ThreadProc()
   {
      Console.WriteLine("\nCurrent thread: {0}", Thread.CurrentThread.Name);
      if (Thread.CurrentThread.Name == "Thread1" && 
          thread2.ThreadState != ThreadState.Unstarted)
         thread2.Join();
      
      Thread.Sleep(4000);
      Console.WriteLine("\nCurrent thread: {0}", Thread.CurrentThread.Name);
      Console.WriteLine("Thread1: {0}", thread1.ThreadState);
      Console.WriteLine("Thread2: {0}\n", thread2.ThreadState);
   }

      thread1.Name = "Thread1"
      thread1.Start()

' The example displays output like the following :

'       
'       
'       Current thread: Thread1
'       Thread1: Running
'       Thread2: Stopped

Si el subproceso ya ha finalizado cuando Join se llama a, el método vuelve inmediatamente.If the thread has already terminated when Join is called, the method returns immediately.

Advertencia

Nunca se debe llamar al Join método Thread del objeto que representa el subproceso actual del subproceso actual.You should never call the Join method of the Thread object that represents the current thread from the current thread. Esto hace que la aplicación deje de responder porque el subproceso actual espera indefinidamente,This causes your app to become unresponsive because the current thread waits upon itself indefinitely,

Este método cambia el estado del subproceso de llamada que ThreadState.WaitSleepJoinse va a incluir.This method changes the state of the calling thread to include ThreadState.WaitSleepJoin. No se puede Join invocar en un subproceso que ThreadState.Unstarted se encuentra en el estado.You cannot invoke Join on a thread that is in the ThreadState.Unstarted state.

Join(Int32)es un método de sincronización que bloquea el subproceso que realiza la llamada (es decir, el subproceso que llama al método Join ) hasta que el subproceso al que se llama se haya completado o hasta que haya transcurrido el intervalo de tiempo de espera.Join(Int32) is a synchronization method that blocks the calling thread (that is, the thread that calls the method) until either the thread whose Join method is called has completed or the time-out interval has elapsed. En el ejemplo siguiente, el Thread1 subproceso llama Join() al método Thread2de, que Thread1 hace que se bloquee hasta que Thread2 se haya completado o dos segundos.In the following example, the Thread1 thread calls the Join() method of Thread2, which causes Thread1 to block either until Thread2 has completed or 2 seconds have elapsed.
