First, create a server program. Then, use the console program of.

The Code is as follows:

Using system; using system. collections. generic; using system. LINQ; using system. text; using system. net. sockets; namespace socketserver {class program {const int Port = 20000; // set the connection port Static void main (string [] ARGs) {// initialize serverip system. net. IPaddress socketip = system. net. IPaddress. parse ("127.0.0.1"); // create the TCP listener tcplistener listener = new tcplistener (socketip, Port); listener. start (); // display the server Start information console. writeline ("the service is being enabled... \ n "); // cyclically accept the client connection request while (true) {chatclient Client client = new chatclient (listener. accepttcpclient (); // displays the IP address and port console used to connect to the client. writeline (client. _ clientip + "?... \ N ");}}}}

Using system; using system. collections. generic; using system. LINQ; using system. text; using system. collections; using system. net. sockets; namespace socketserver {class chatclient {public static hashtable allclients = new hashtable (); // Private tcpclient _ client in the customer list; // Public String _ clientip in the client object; // Client IP private string _ clientnick; // client nickname private byte [] data; // message data private bool incluenick = T Rue; Public chatclient (tcpclient client) {This. _ client = client; this. _ clientip = client. Client. remoteendpoint. tostring (); // Add the current client instance? In the customer list, allclients. add (this. _ clientip, this); Data = new byte [this. _ client. receivebuffersize]; // obtain the message client from the server. getstream (). beginread (data, 0, system. convert. toint32 (this. _ client. receivebuffersize), receivemessage, null);} // obtain the public void receivemessage (iasyncresult AR) {int bytesread; try {lock (this. _ client. getstream () {bytesread = This. _ client. getstream (). endread (AR);} If (bytesread <1) {allclients. remove (this. _ clientip); broadcast (this. _ clientnick + "leaving the chat room"); return;} else {string messagereceived = system. text. encoding. ASCII. getstring (data, 0, bytesread); If (enick) {This. _ clientnick = messagereceived; broadcast (this. _ clientnick + "join chat room"); enick = false;} else {broadcast (this. _ clientnick + ":" + messagereceived) ;}} lock (this. _ client. getstream () {This. _ client. getstream (). beginread (data, 0, system. convert. toint32 (this. _ client. receivebuffersize), receivemessage, null) ;}} catch (exception ex) {allclients. remove (this. _ clientip); broadcast (this. _ clientnick + "Leave chatting room") ;}// send the public void sendmessage (string message) {try {system. net. sockets. networkstream ns; lock (this. _ client. getstream () {NS = This. _ client. getstream () ;}// encode the information byte [] bytestosend = system. text. encoding. ASCII. getbytes (Message); NS. write (bytestosend, 0, bytestosend. length); NS. flush () ;}catch (exception ex) {}// broadcast the public void broadcast (string message) {console to the client. writeline (Message); foreach (dictionaryentry C in allclients) {(chatclient) (C. value )). sendmessage (Message + environment. newline );}}}}

This is easier than just others. I copied other people's Code directly. It is better to understand than others. It is suitable for beginners ~~~ (If any copyright infringement occurs, please contact me by private letter)

The following is the code on the unity side ~

The Code is as follows:

Using unityengine; using system. collections; using system. collections. generic; using system. componentmodel; using system. text; using system. net. sockets; public class scoketclient: monobehaviour {const int Port = 20000; // port number and server port corresponding private tcpclient client; byte [] data; Public String username = ""; // username Public String message = ""; // chat content Public String sendmsg = ""; // input box void ongui () {username = GUI. textfield (New rect (10, 10,100, 20), username); message = GUI. textarea (New rect (10, 40,300,200), message); sendmsg = GUI. textfield (New rect (10,250,210, 20), sendmsg); If (GUI. button (New rect (120, 10, 80, 20), "connect to server") {This. client = new tcpclient (); this. client. connect ("127.0.0.1", Port); Data = new byte [this. client. receivebuffersize]; sendsocket (username); this. client. getstream (). beginread (data, 0, system. convert. toint32 (this. client. receivebuffersize), receivemessage, null) ;}; if (GUI. button (New rect (230,250, 80, 20), "send") {sendsocket (sendmsg); sendmsg = "" ;};} public void sendsocket (string message) {try {networkstream NS = This. client. getstream (); byte [] DATA = system. text. encoding. ASCII. getbytes (Message); NS. write (data, 0, Data. length); NS. flush ();} catch (exception ex) {}} public void receivemessage (iasyncresult AR) {try {int bytesread; bytesread = This. client. getstream (). endread (AR); If (bytesread <1) {return;} else {message + = system. text. encoding. ASCII. getstring (data, 0, bytesread);} This. client. getstream (). beginread (data, 0, system. convert. toint32 (this. client. receivebuffersize), receivemessage, null);} catch (exception ex ){}}}

In this way, you can ~ Enable the server first, and then connect with the client.

The encoding is ASCII. Suppose you want to use Chinese words into UTF-8, or gb2312.
