Communication between the B/S mode and the C/S Mode in C #-socket communication

I) Background:

In many systems, the B/S architecture and the C/S architecture are included. This involves the communication between B/S and C/S, I have also discussed this issue in csdn forums.

And you have discussed the master, the specific post: http://topic.csdn.net/u/20100326/09/dd9ee3ce-3d90-4583-8eaf-d8542d7eec72.html

In general, two solutions are provided:

1) communicate through WebService. 2) communication through WCF

However, I do not know much about WebService and WCF, So I considered another method and used socket for communication.

Ii) server-side test code:

Private bool islistening = false; <br/> private void button#click (Object sender, eventargs e) <br/>{< br/> If (! Islistening) <br/>{< br/> // create a TCP/IP socket for listening to client connections <br/> socket listensocket = new socket (addressfamily. interNetwork, sockettype. stream, protocoltype. <br/> int Port = 8000; <br/> string host = "192.168.1.222 "; // ip address used for network connection <br/> // string host = "127.0.0.1"; // used when the network is not connected <br/> iphostentry entry = DNS. gethostentry (host); <br/> IPaddress IP = entry. addresslist [0]; <br/> /// first bind the host and port to be listened on, so that The socket is associated with a local endpoint. <Br/> listensocket. BIND (New ipendpoint (IP, Port); <br/> // start listening and specify the maximum length of the listening queue <br/> listensocket. listen (10); <br/> islistening = true; <br/> // The thread is blocked until a new client connection exists. <br/> listensocket. beginaccept (New asynccallback (this. onacceptsocket), null); <br/> addmsg ("Start listening... "); <br/> // generate the main thread and start the main thread <br/> thread tmain = new thread (New threadstart (testmainrepart); <br/> tmain. start (); <br/>}< br/> else <br/> {<B R/> MessageBox. Show ("the service is enabled! "); <Br/>}</P> <p>}

 

Private void onacceptsocket (iasyncresult AR) <br/>{< br/> If (! Islistening) <br/> return; <br/> socket S = listensocket. endaccept (AR); <br/> mysocket socket = new mysocket (); <br/> socket. socket = s; <br/> socket. isconnected = true; <br/> socket. socket. beginreceive (socket. buffer, 0, mysocket. bufsize, socketflags. none, new asynccallback (this. onreceivedata), socket); <br/> listensocket. beginaccept (New asynccallback (this. onacceptsocket), null); <br/>}

 

 

Private void onreceivedata (iasyncresult AR) <br/>{< br/> mysocket socket = ar. asyncstate as mysocket; <br/> If (socket = NULL |! Socket. isconnected) <br/> return; <br/> int length = socket. socket. endreceive (AR); <br/> // MSG indicates the accepted data. <br/> string MSG = encoding. utf8.getstring (socket. buffer, 0, length); <br/> // send the received data to the client. <br/> socket. send (MSG); <br/>}

 

Public class mysocket <br/>{< br/> private Socket socket; <br/> private bool isconnected; <br/> private byte [] Buf; <br/> private string clientname; <br/> Public const int bufsize = 8192; <br/> Public const string exitcode = "exit "; <br/> Public mysocket (string clientname, Socket socket, byte [] BUF) <br/>{< br/> This. clientname = clientname; <br/> This. socket = socket; <br/> This. buf = Buf; <br/> This. isconnected = false; <br/>}< br/> Public mysocket (string clientname, Socket socket) <br/>: This (clientname, socket, new byte [bufsize]) <br/>{< br/>}< br/> Public mysocket (string clientname) <br/>: This (clientname, new socket (addressfamily. interNetwork, sockettype. stream, protocoltype. TCP) <br/>{< br/>}< br/> Public mysocket () <br/>{< br/> This. buf = new byte [bufsize]; <br/>}< br/> Public Socket socket <br/>{< br/> get {return socket ;} <br/> set {socket = value ;}< br/>}< br/> Public bool isconnected <br/>{< br/> get {return isconnected ;} <br/> set {isconnected = value ;}< br/>}< br/> Public String clientname <br/>{< br/> get {return clientname ;} <br/> set {clientname = value ;}< br/>}< br/> Public byte [] buffer <br/>{< br/> get {return Buf ;} <br/>}< br/> Public void sendmessage (string MSG) <br/>{< br/> byte [] Buf = encoding. utf8.getbytes (MSG); <br/> socket. beginsend (BUF, 0, Buf. length, socketflags. none, new asynccallback (sendcallback), socket); <br/>}< br/> Public void sendcallback (iasyncresult IR) <br/>{< br/> try <br/> {<br/> Socket socket = (socket) IR. asyncstate; <br/> socket. endsend (IR); <br/>}< br/> catch <br/>{< br/>}< br/>}

 

 

 

Iii) client code:

 

Protected void button1_click (Object sender, eventargs e) <br/>{< br/> int Port = 8000; <br/> string host = "192.168.1.222 "; <br/> // string host = "127.0.0.1"; <br/> IPaddress IP = IPaddress. parse (host); <br/> ipendpoint IPE = new ipendpoint (IP, Port); <br/> socket c = new socket (addressfamily. interNetwork, sockettype. stream, protocoltype. TCP); <br/> C. connect (IPE); <br/> string STR = "data to be sent"; <br/> byte [] BS = encoding. utf8.getbytes (STR); <br/> // send data <br/> C. send (BS, BS. length, 0); <br/> string recvstr = ""; <br/> byte [] recvbytes = new byte [1024]; <br/> int bytes; <br/> bytes = C. receive (recvbytes, recvbytes. length, 0); <br/> // recvstr indicates the received data. <br/> recvstr + = encoding. utf8.getstring (recvbytes, 0, bytes); <br/> C. close (); <br/>}< br/>
