這期內(nèi)容當(dāng)中小編將會(huì)給大家?guī)?lái)有關(guān)怎么在C# .NET中使用Socket框架,文章內(nèi)容豐富且以專(zhuān)業(yè)的角度為大家分析和敘述,閱讀完這篇文章希望大家可以有所收獲。

第一步:服務(wù)端監(jiān)聽(tīng)某個(gè)端口
第二步:客戶(hù)端向服務(wù)端地址和端口發(fā)起Socket連接請(qǐng)求
第三步:服務(wù)端收到連接請(qǐng)求后創(chuàng)建Socket連接,并維護(hù)這個(gè)連接隊(duì)列。
第四步:客戶(hù)端和服務(wù)端已經(jīng)建立雙工通信(即雙向通信),客戶(hù)端和服務(wù)端可以輕松方便的給彼此發(fā)送信息。
至于簡(jiǎn)單使用的具體實(shí)現(xiàn)代碼全部被我封裝到項(xiàng)目中了,如果需要學(xué)習(xí)簡(jiǎn)單的實(shí)現(xiàn),可以看我的源碼,也可以自行百度,有很多的教程
2、核心,框架的使用
其實(shí),說(shuō)其為框架,可能有點(diǎn)牽強(qiáng),因?yàn)槊總€(gè)人對(duì)框架都有自己的理解,但是類(lèi)庫(kù)和框架又有什么本質(zhì)區(qū)別呢?全部都是代碼~哈哈,扯遠(yuǎn)了
首先,空說(shuō)無(wú)憑,先放上所有的代碼:

上面放上的是框架代碼,接下來(lái)介紹下如何使用
首先,服務(wù)端使用方式:
using Coldairarrow.Util.Sockets; using System; using System.Text; namespace Console_Server { class Program { static void Main(string[] args) { //創(chuàng)建服務(wù)器對(duì)象,默認(rèn)監(jiān)聽(tīng)本機(jī)0.0.0.0,端口12345 SocketServer server = new SocketServer(12345); //處理從客戶(hù)端收到的消息 server.HandleRecMsg = new Action<byte[], SocketConnection, SocketServer>((bytes, client, theServer) => { string msg = Encoding.UTF8.GetString(bytes); Console.WriteLine($"收到消息:{msg}"); }); //處理服務(wù)器啟動(dòng)后事件 server.HandleServerStarted = new Action<SocketServer>(theServer => { Console.WriteLine("服務(wù)已啟動(dòng)************"); }); //處理新的客戶(hù)端連接后的事件 server.HandleNewClientConnected = new Action<SocketServer, SocketConnection>((theServer, theCon) => { Console.WriteLine($@"一個(gè)新的客戶(hù)端接入,當(dāng)前連接數(shù):{theServer.ClientList.Count}"); }); //處理客戶(hù)端連接關(guān)閉后的事件 server.HandleClientClose = new Action<SocketConnection, SocketServer>((theCon, theServer) => { Console.WriteLine($@"一個(gè)客戶(hù)端關(guān)閉,當(dāng)前連接數(shù)為:{theServer.ClientList.Count}"); }); //處理異常 server.HandleException = new Action<Exception>(ex => { Console.WriteLine(ex.Message); }); //服務(wù)器啟動(dòng) server.StartServer(); while (true) { Console.WriteLine("輸入:quit,關(guān)閉服務(wù)器"); string op = Console.ReadLine(); if (op == "quit") break; } } } }
客戶(hù)端使用方式:
using Coldairarrow.Util.Sockets; using System; using System.Text; namespace Console_Client { class Program { static void Main(string[] args) { //創(chuàng)建客戶(hù)端對(duì)象,默認(rèn)連接本機(jī)127.0.0.1,端口為12345 SocketClient client = new SocketClient(12345); //綁定當(dāng)收到服務(wù)器發(fā)送的消息后的處理事件 client.HandleRecMsg = new Action<byte[], SocketClient>((bytes, theClient) => { string msg = Encoding.UTF8.GetString(bytes); Console.WriteLine($"收到消息:{msg}"); }); //綁定向服務(wù)器發(fā)送消息后的處理事件 client.HandleSendMsg = new Action<byte[], SocketClient>((bytes, theClient) => { string msg = Encoding.UTF8.GetString(bytes); Console.WriteLine($"向服務(wù)器發(fā)送消息:{msg}"); }); //開(kāi)始運(yùn)行客戶(hù)端 client.StartClient(); while (true) { Console.WriteLine("輸入:quit關(guān)閉客戶(hù)端,輸入其它消息發(fā)送到服務(wù)器"); string str = Console.ReadLine(); if (str == "quit") { client.Close(); break; } else { client.Send(str); } } } } }
最后運(yùn)行測(cè)試截圖:
