问题描述
刚接触c#，求指教。用多个是win7.实现局域网基于c/s文件传输，代码如下服务端：classFTServerCode{IPEndPointipEnd;Socketsock;publicFTServerCode(){ipEnd=newIPEndPoint(IPAddress.Any,5656);sock=newSocket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.IP);sock.Bind(ipEnd);}publicstaticstringreceivedPath;publicstaticstringcurMsg="Stopped";publicvoidStartServer(){try{curMsg="Starting...";sock.Listen(100);curMsg="Runningandwaitingtoreceivefile.";SocketclientSock=sock.Accept();byte[]clientData=newbyte[1024*5000];intreceivedBytesLen=clientSock.Receive(clientData);curMsg="Receivingdata...";intfileNameLen=BitConverter.ToInt32(clientData,0);stringfileName=Encoding.ASCII.GetString(clientData,4,fileNameLen);BinaryWriterbWrite=newBinaryWriter(File.Open(receivedPath+"/"+fileName,FileMode.Append));;bWrite.Write(clientData,4+fileNameLen,receivedBytesLen-4-fileNameLen);curMsg="Savingfile...";bWrite.Close();clientSock.Close();curMsg="Reeived&Savedfile;ServerStopped.";}catch(Exceptionex){curMsg="FileRecevingerror.";}}}}客户端：classFTClientCode{publicstaticstringcurMsg="Idle";publicstaticvoidSendFile(stringfileName){try{IPAddress[]ipAddress=Dns.GetHostAddresses("localhost");IPEndPointipEnd=newIPEndPoint(ipAddress[0],5656);SocketclientSock=newSocket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.IP);stringfilePath="";fileName=fileName.Replace("\","/");while(fileName.IndexOf("/")>-1){filePath+=fileName.Substring(0,fileName.IndexOf("/")+1);fileName=fileName.Substring(fileName.IndexOf("/")+1);}byte[]fileNameByte=Encoding.ASCII.GetBytes(fileName);if(fileNameByte.Length>850*1024){curMsg="Filesizeismorethan850kb,pleasetrywithsmallfile.";return;}curMsg="Buffering...";byte[]fileData=File.ReadAllBytes(filePath+fileName);byte[]clientData=newbyte[4+fileNameByte.Length+fileData.Length];byte[]fileNameLen=BitConverter.GetBytes(fileNameByte.Length);fileNameLen.CopyTo(clientData,0);fileNameByte.CopyTo(clientData,4);fileData.CopyTo(clientData,4+fileNameByte.Length);curMsg="Connectiontoserver...";clientSock.Connect(ipEnd);curMsg="Filesending...";clientSock.Send(clientData);curMsg="Disconnecting...";clientSock.Close();curMsg="Filetransferred.";}catch(Exceptionex){if(ex.Message=="Noconnectioncouldbemadebecausethetargetmachineactivelyrefusedit")curMsg="FileSendingfail.Becauseservernotrunning.";elsecurMsg="FileSendingfail."+ex.Message;}}}}

解决方案二：
解决方案三：
IPAddressHostIp=IPAddress.Any;IPEndPointiep=newIPEndPoint(HostIp,9090);SocketserverSocket=newSocket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);serverSocket.Bind(iep);serverSocket.Listen(10);http://bbs.csdn.net/topics/360017799摘自三楼，另外http://blog.csdn.net/lovexiaoxiao/article/details/6328441
