100分高分求助~！关于判断多线程是否结束
高分求助~~
小弟开启了100个进程，想让进程所有的进程都结束后转到“showhtml”页面。现在我不会做判断进程是否全部结束~

protected void search_Click(object sender, EventArgs e)
    {
        int Start = 0;
        string question = TextBox1.Text.ToString();
        if (question.Equals(""))
        {
            Response.Write("请输入您要查询的内容！");

        }
        else
        {
            Response.Write("正在查询并下载网页...");   
            Thread[] myThread;//声名下载线程
            int n = 1;//设置线程总数，同时规定下载的连接数 此处为1000，即下载1000个链接
            myThread = new Thread[ n ];//为线程申请资源，确定线程总数
            for( int i = 0; i < n; i++ )
            {
                Start = i * 10;
                string gurl = "http://www.google.com/search?q=" + System.Web.HttpUtility.UrlEncode(question) + "&start=" + Start;//按照UTF8编码
                imple myimpl = new imple(gurl, question,Start);
                ThreadStart startDownload = new ThreadStart(myimpl.getgoogle);
                myThread[i] = new Thread( startDownload );//指定线程起始设置
                myThread[i].Start();//逐个开启线程
                //判断线程是不是结束~

                int time = new Random().Next(1000);//休眠1000毫秒内的随机数
                Thread.Sleep(time);
               
            }
            //while (IsAlive)？？？该怎么写呢？
            //{ }
        }
       
    }

很急~~谢谢大侠们了

while(CheckIsStop(myThread,n))

   Response.Redirect("show.html"); 
 
}


public bool CheckIsStop(Thread[] myThread, int n)

[解决办法]
上面逻辑不对，重写了下

bool isStop=false;
while(!isStop)
{
   isStop=CheckIsStop(myThread,n);
}
Response.Redirect("show.html");



public bool CheckIsStop(Thread[] myThread, int n)
{
for( int i = 0; i < n; i++ )
{
   if(myThread[i].ThreadState!=ThreadState.Aborted)
   {
      return false;
   }
}
return true;
}

[解决办法]

引用:

C# code

int num = 0, num1 = 0, num2 = 0, num3 = 0;

System.Threading.Thread thread1 = new System.Threading.Thread(delegate()
……

up

  while(true)
  {
    if(thread1.ThreadState!=Sytem.Threading.ThreadState.Stopped) continus;
  }
