C#使用Socket實現本地多人聊天室
本文實例為大傢分享瞭C#使用Socket實現本地多人聊天室的具體代碼,供大傢參考,具體內容如下
【腳本一:Server端】
使用本機地址:127.0.0.1
完整代碼
using System; using System.Collections.Generic; using System.Net; using System.Net.Sockets; using System.Text; using System.Threading; namespace ConsoleApp1 { public class Server { Socket mySocket = null; Dictionary<IPAddress, Socket> cliDic = new Dictionary<IPAddress, Socket>(); public void Connect(int port) { string IP = "127.0.0.1"; //IPAddress IPAddress = IPAddress.Parse("127.0.0.1"); IPAddress address = IPAddress.Any; //創建IP終結點,把IP地址與端口綁定到網絡終結點上 IPEndPoint endPoint = new IPEndPoint(address, port); //創建客戶端套接字 mySocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); ///監聽套接字終結點 mySocket.Bind(endPoint); //服務端可接收客戶端連接數量為無限個 mySocket.Listen(0); //開啟線程監聽客戶端 Thread myThread = new Thread(Listen_Con); myThread.Start(); Console.WriteLine("開始監聽..."); } /// <summary> /// 接收連接的客戶端並存儲客戶端的信息 /// </summary> /// <param name="obj"></param> public void Listen_Con(Object obj) { Socket cliSocket = null; //持續監聽客戶端的請求 while (true) { try { cliSocket = mySocket.Accept(); } catch (Exception e) { Console.WriteLine(e.Message); } string cliEndPoint = cliSocket.RemoteEndPoint.ToString(); IPAddress cliAddress = (cliSocket.RemoteEndPoint as IPEndPoint).Address; int cliPort = (cliSocket.RemoteEndPoint as IPEndPoint).Port; cliDic.Add(cliAddress, cliSocket); string MsgStr = "[客戶端結點:" + cliEndPoint + "\n+客戶端IP:" + cliAddress.ToString() + "\n客戶端端口:" + cliPort.ToString() + "\n已連接]"; byte[] MsgBytes = Encoding.UTF8.GetBytes(MsgStr); cliSocket.Send(MsgBytes); Thread rec_Cli = new Thread(Receive_Con); rec_Cli.Start(cliSocket); Thread sed_Cli = new Thread(SendToCli); sed_Cli.Start(cliSocket); } } /// <summary> /// 接收已連接的客戶端發送的消息 /// </summary> /// <param name="socket"></param> public void Receive_Con(Object socket) { Socket client = socket as Socket; while (true) { //創建大小為1024*1024的內存緩沖區(1M) byte[] recBytes = new byte[1024 * 1024]; //嘗試把接收的字節存儲到緩沖區 try { int length = client.Receive(recBytes); //把機器接收的字節數組轉換為string string recMsg = Encoding.UTF8.GetString(recBytes, 0, length); //將服務器接收到的信息轉發到所有已連接的客戶端 if (cliDic.Count > 0) { foreach (var soc in cliDic) { soc.Value.Send(Encoding.UTF8.GetBytes("[" + soc.Value.RemoteEndPoint + "]:" + recMsg)); } } Console.WriteLine("[" + client.RemoteEndPoint + "]:" + recMsg); } catch (Exception) { cliDic.Remove((client.RemoteEndPoint as IPEndPoint).Address); //客戶端斷開的異常 Console.WriteLine("[客戶端" + (client.RemoteEndPoint as IPEndPoint).Address + "已斷開]"); Console.WriteLine("[客戶端終結點:" + client.RemoteEndPoint+"]"); //斷開套接字 client.Close(); break; } } } public void SendToCli(object obj) { Socket curCliSoc = obj as Socket; while (true) { byte[] ByteToAll = new byte[1024 * 1024]; try { string MsgToAll = Console.ReadLine(); ByteToAll = Encoding.UTF8.GetBytes("[服務端]:"+MsgToAll); curCliSoc.Send(ByteToAll); } catch(Exception) { Console.WriteLine("ERROR:" + curCliSoc.RemoteEndPoint + "已與服務端斷開!"); curCliSoc.Close(); if(cliDic.ContainsKey((curCliSoc.RemoteEndPoint as IPEndPoint).Address)) { cliDic.Remove((curCliSoc.RemoteEndPoint as IPEndPoint).Address); } } } } } public class ServerMain { static void Main(string[] args) { Server s1 = new Server(); s1.Connect(8800); } } }
Server端運行結果:
【腳本二:Client端】
完整代碼
using System; using System.Net; using System.Net.Sockets; using System.Text; using System.Threading; namespace ConsoleApp1 { public class Client { string SerIP = "127.0.0.1"; Socket myClient = null; Thread ConnectThread = null; IPAddress SerAdd; IPEndPoint SerEP; public void Connect_To_Ser(int port) { myClient = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); SerAdd = IPAddress.Parse(SerIP); SerEP = new IPEndPoint(SerAdd, port); while (true) { try { myClient.Connect(SerEP); break; } catch { Console.WriteLine("無法連接到服務端,請重試..."); } } ConnectThread = new Thread(Receive_Ser); ConnectThread.Start(); } public void Receive_Ser() { while (true) { byte[] SerBytes = new byte[1024 * 1024]; try { int length = myClient.Receive(SerBytes); string Msg = Encoding.UTF8.GetString(SerBytes, 0, length); Console.WriteLine(Msg); } catch (Exception) { Console.WriteLine("已與服務端斷開連接..."); break; } } } public void SendToSer() { while (true) { try { string SendMsg = Console.ReadLine(); myClient.Send(Encoding.UTF8.GetBytes(SendMsg)); } catch (Exception) { Console.WriteLine("[SendToSer]已斷開連接"); break; } } } } public class ClienMain { static void Main(string[] Args) { Client c1 = new Client(); c1.Connect_To_Ser(8800); c1.SendToSer(); } } }
客戶端運行效果:
①客戶端先於服務端運行
②客戶端遲於服務端運行
暫時總效果:
功能完善:
①客戶端連上服務端後若服務端斷開再打開,客戶端無法重連
②心跳包重連
