标题: 帮忙解释下这段代码
[code=csharp]private struct SendMessageStates
      {
         public SendMessageDelegate d;
         public IAsyncResult result;
      }

      /// <summary>异步向服务器端发送数据</summary>
      private void AsyncSendMessage(string message)
      {
         SendMessageDelegate d = new SendMessageDelegate(SendMessage);
         IAsyncResult result = d.BeginInvoke(message, null, null);
         while (result.IsCompleted == false)
         {
            if (isExit)
            {
                  return;
            }
            Thread.Sleep(50);
         }
//下面这段没看懂，帮忙解释下
         SendMessageStates states = new SendMessageStates();
         states.d = d;
         states.result = result;
         Thread t = new Thread(FinishAsyncSendMessage);
         t.IsBackground = true;
         t.Start(states);
      }[/code]

[code=csharp]SendMessageStates states = new SendMessageStates();
         states.d = d;
         states.result = result;[/code]
这是New一个结构SendMessageStates 对象名为states 下面是赋值
//开启一个线程技术方法FinishAsyncSendMessage
[code=csharp]Thread t = new Thread(FinishAsyncSendMessage);
         t.IsBackground = true；//设置为后台线程，在后台运行的那种
         t.Start(states);//给这个FinishAsyncSendMessage方法传个参数是states[/code]
其实这里主要解决的是多线程调用有参数的方法的问题，
其它可以更简单就是我常写的那种
如下
[code=csharp]Thread objThread = new Thread(new ThreadStart(delegate
                  {
                  //在这里写你的方法，可以随便写多个方法和参数。这是最方便的
                  }));
                  objThread.Start();[/code]
