C#Socket文件传输

C#SocketSC结构文件传输收藏
下面是服务器端的代码，里面注释都很清楚我就不解释了
Serve form 上有一个btnListen的button,一个表连接状态的：Connection State的label,还有一个表连接状态的txtBox:txtConState

下面是客户端代码,
客户端是有一个，btnBrowse的打开浏览button,加了一个OpenFileDialog控件,一个btnSendFile的文件传输button,一个用于显示地址的文本框：txtFilePath

IPEndPoint ipEndP = new IPEndPoint(ipAddr, 11000);
Socket client = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
//connect
client.Connect(ipEndP);
Console.WriteLine("Sending {0} to the Host", filename);
client.SendFile(filename);
//to shutdown the Server'receive and Client'send
client.Shutdown(SocketShutdown.Both);
client.Close();
