Win7下Socket服务端通信异常退出
本帖最后由 zpj888 于 2012-12-29 15:22:36 编辑 socket通信时，服务端会造成程序死掉，而且是无法捕捉到的异常退出
经过数天多次测试，XP下正常，绝大部分的WIN7系统会退。
以下是写的专门用于测试该问题的小程序，一个服务端，一个客户端。
其中服务端开始后，客户端指定本机的IP地址即可，注意不要使用回环地址，测试时发现回环地址不容易退。
客户端连接200个socket，每个socket频繁收发数据，很快程序退出
开发环境：VS2010，C#，Dot Net4.0
完整程序及代码链接：http://l5.yunpan.cn/lk/QkBwwZxj6wDzT
（代码没有处理各种连接及断开的异常情况，不影响测试）
请各位帮忙看看问题所在，是不是WIN7的什么补丁要装一下？测试WIN7机装了SP1,拿360打了所有补丁，一样会退
