故事
我正在尝试编写一个开源RPG库存服务器，可以同时使用一个以上的RPG，并且稍后会为它制作一个游戏。我的第一个版本不支持很多安全性或加密。但我想有一个良好的开端。
问题
它接受一个连接，掉线。但我的线程实现似乎只接受一个连接。有人可以给我一个如何正确做到这一点的指导方针吗？我已经评论了我将为您的阅读提供的代码。
设置 我使用启用了SP1的visual studio 2010。我只在家庭网络中尝试过，因此不需要IP转发。它同时接受两台PC。
非常感谢帮助的人，如果你有所帮助，并希望在最终结果中得到记录，请告诉我。如果有人有一般性评论，我很乐意听到他们的意见;）
编辑：它与NewIPEP（）方法有关。

答案 0 :(得分：1)
您只调用了Socket client = newsock.Accept();一次，这就是为什么只接受一个客户端的原因。

这不是答案，但我不知道如何添加评论......你有没有检查过Lidgren？为什么重新发明轮子？ http://code.google.com/p/lidgren-network-gen3/
他有关如何使用该库的相同的很好的例子。
祝你好运！Linuxx
