// Keep on accepting Client Connection
while (true)
{
// New Client connected, call Event to handle it.
Thread t = new Thread(new ParameterizedThreadStart(NewClient));
TcpCli = TcpSer.AcceptTcpClient();
t.Start(TcpCli);
}
}
树形视图必须打印所有连接到服务器的客户端
但什么都没印刷
在此先感谢
the tree view must print all client connect to the server
but nothing printed
thanks in advance
推荐答案
您好，
我自己完成了这项工作，并且知道要花多少钱才能开始工作.您可能希望看一下我的文章，特别是这篇文章:
快速网络库2 [ http://networkinglibrary.codeplex.com/ [ ^ ]
希望这会有所帮助，
埃德
P.s.确保您的服务器正在侦听IPv4地址，并且您的客户端也在尝试连接到IPv4版本，这可能是您的问题.
Hi there,
I have done this myself and know how much of a pin it s to get working. You may wish to take a look at my articles, in particular this one:
Fast Networking Library 2[^]
or take a look at my latest version of it on CodePlex:
http://networkinglibrary.codeplex.com/[^]
Hope this helps,
Ed
P.s. Make sure your server is listeneing on the IPv4 address and that your client is also trying to connect to the IPv4 version, this may be your problem.
