线程的执行上下文

你的目的是什么 ExecutionContext.SuppressFlow(); 到底什么会被压制?

我有这个测试代码。。。

protected void btnSubmit_Click(object sender, EventArgs e)
{
   Thread[] th = new Thread[100];
   Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-GB");

   AsyncFlowControl cntrl = ExecutionContext.SuppressFlow();
   for (int i = 0; i < th.Length; i++)
   {                   
      th[i] = new Thread(new ParameterizedThreadStart(ThreadMethod));
      th[i].Name = "Thread #" + (i+1).ToString();                
      th[i].Start((i+1).ToString());
   }
   ExecutionContext.RestoreFlow();

   foreach (Thread t in th)            
   {
      t.Join();
   }
   Response.Write(response);
}


String response = null;
Random rnd = new Random(1000);
private void ThreadMethod(object param)
{   
   if (param != null)
   {
      string temp = param as string;
      if (temp != null)
      {
         //To test what is the current culture I get for this thread execution
         System.Globalization.CultureInfo info = Thread.CurrentThread.CurrentCulture;
         for (int i = 0; i <= 10; i++)
         {
            Thread.Sleep(rnd.Next(2000));
            response += Thread.CurrentThread.ManagedThreadId.ToString() + ":" 
                     + Thread.CurrentThread.Name + ": " + temp + "<br/>";
         }
      }
   }
}
