socket写即时通讯软件，求解决

Question

socket即时通讯软件

Answer 1

在调试时没事，不会自动重启。但是打开debug里的exe就会重启。

Answer 2

trycatch可能是客户端掉线了...

Answer 3

这是服务器前一部分的代码，我觉得应该是这部分的问题，后面的代码都是传递聊天信息啥的了

Answer 4

你调试的时候是不是打断点了，然后程序能正常运行，如果是这样，你把线程sleep一秒试试，很有可能是一直处于监听状态，自己卡死的

Answer 5

不打断点的话，调试时也能正常运行。就是打开exe时监听时间长了没消息的话，就自动重启了

Answer 6

   Thread myThread = new Thread(ListenClientConnect);
            myThread.Start();
            btn_Start.Enabled = false;
            btn_Stop.Enabled = true;
在点击函数分配了一个线程,结果被垃圾内存回收机制给回收了.
可以把Thread myThread 放到外边窗体的成员变量上看下.

Answer 7

这段代码可能会出现异常的地方不少，可以在每个函数体中另try catch捕获一下，以确定到底在哪里出现问题了
