Csharp/C#教程：SuperSocket封装成C#类库的步骤分享

将SuperSocket封装成类库之后可以将其集成进各种类型的应用，而不仅仅局限于控制台应用程序了，从而应用于不同的场景。这里以TelnetServer为例说明如何进行操作。

首先，创建一个C#类库项目LibSocketServer

添加SuperSocket引用（SuperSocket.Common.dll，SuperSocket.SocketBase.dll，SuperSocket.SocketEngine.dll），添加默认的日志框架log4net.dll引用。将log4net.config拷贝到项目文件夹的“Config”文件夹，然后设置它的“生成操作”为“内容”，设置它的“复制到输出目录”为“如果较新则复制”。

其次，添加SuperSocket完整的TelnetServer服务相关类，Socket服务管理类SocketServerManager。

其中SocketServerManager对Bootstrap的设置是SuperSocket封装为类库的关键。

TelnetSession.cs

usingSystem; usingSuperSocket.SocketBase; usingSuperSocket.SocketBase.Protocol;   namespaceLibSocketServer.Server {     publicclassTelnetSession:AppSession<TelnetSession>     {         protectedoverridevoidOnSessionStarted()         {             Console.WriteLine($"NewSessionConnected:{RemoteEndPoint.Address}"+                               $"@{RemoteEndPoint.Port}.");             Send("WelcometoSuperSocketTelnetServer.");         }           protectedoverridevoidHandleUnknownRequest(StringRequestInforequestInfo)         {             Console.WriteLine($"Unknownrequest{requestInfo.Key}.");             Send("Unknownrequest.");         }           protectedoverridevoidHandleException(Exceptione)         {             Console.WriteLine($"Applicationerror:{e.Message}.");             Send($"Applicationerror:{e.Message}.");         }           protectedoverridevoidOnSessionClosed(CloseReasonreason)         {             Console.WriteLine($"Session{RemoteEndPoint.Address}@{RemoteEndPoint.Port}"+                               $"Closed:{reason}.");             base.OnSessionClosed(reason);         }     } }

TelnetServer.cs

usingSystem; usingSuperSocket.SocketBase; usingSuperSocket.SocketBase.Config;   namespaceLibSocketServer.Server {     publicclassTelnetServer:AppServer<TelnetSession>     {         protectedoverrideboolSetup(IRootConfigrootConfig,IServerConfigconfig)         {             Console.WriteLine("TelnetServerSetup");             returnbase.Setup(rootConfig,config);         }           protectedoverridevoidOnStarted()         {             Console.WriteLine("TelnetServerOnStarted");             base.OnStarted();         }           protectedoverridevoidOnStopped()         {             Console.WriteLine();             Console.WriteLine("TelnetServerOnStopped");             base.OnStopped();         }     } }

AddCommand.cs

usingSystem; usingSystem.Linq; usingLibSocketServer.Server; usingSuperSocket.SocketBase.Command; usingSuperSocket.SocketBase.Protocol;   namespaceLibSocketServer.Command {     publicclassAddCommand:CommandBase<TelnetSession,StringRequestInfo>     {         publicoverridestringName=>"ADD";         publicoverridevoidExecuteCommand(TelnetSessionsession,StringRequestInforequestInfo)         {             Console.WriteLine($"{Name}command:{requestInfo.Body}.");             session.Send(requestInfo.Parameters.Select(p=>Convert.ToInt32(p)).Sum().ToString());         }     } }

EchoCommand.cs

usingSystem; usingLibSocketServer.Server; usingSuperSocket.SocketBase.Command; usingSuperSocket.SocketBase.Protocol;   namespaceLibSocketServer.Command {     publicclassEchoCommand:CommandBase<TelnetSession,StringRequestInfo>     {         publicoverridestringName=>"ECHO";         publicoverridevoidExecuteCommand(TelnetSessionsession,StringRequestInforequestInfo)         {             Console.WriteLine($"{Name}command:{requestInfo.Body}.");             session.Send(requestInfo.Body);         }     } }

SocketServerManager.cs

usingSystem; usingSystem.Reflection; usingSuperSocket.SocketBase; usingSuperSocket.SocketEngine;   namespaceLibSocketServer {     publicclassSocketServerManager     {         privatereadonlyIBootstrap_bootstrap;           publicboolStartup(intport)         {             if(!_bootstrap.Initialize())             {                 Console.WriteLine("SuperSocketFailedtoinitialize!");                 returnfalse;             }               varret=_bootstrap.Start();             Console.WriteLine($"SuperSocketStartresult:{ret}.");               returnret==StartResult.Success;         }           publicvoidShutdown()         {             _bootstrap.Stop();         }           #regionSingleton           privatestaticSocketServerManager_instance;         privatestaticreadonlyobjectLockHelper=newobject();           privateSocketServerManager()         {             varlocation=Assembly.GetExecutingAssembly().Location;             varconfigFile=$"{location}.config";             _bootstrap=BootstrapFactory.CreateBootstrapFromConfigFile(configFile);         }           publicstaticSocketServerManagerInstance         {             get             {                 if(_instance!=null)                 {                     return_instance;                 }                   lock(LockHelper)                 {                     _instance=_instance??newSocketServerManager();                 }                   return_instance;             }         }           #endregion     } } 再次，添加配置文件App.config到类库中，并设置其配置参数。 <?xmlversion="1.0"encoding="utf-8"?> <configuration>     <configSections>         <sectionname="superSocket"                  type="SuperSocket.SocketEngine.Configuration.SocketServiceConfig,SuperSocket.SocketEngine"/>     </configSections>       <!--SuperSocket配置的根节点-->     <superSocket>         <!--服务器实例-->         <servers>             <servername="TelnetServer"serverTypeName="TelnetServerType"ip="Any"port="2021"></server>         </servers>           <!--服务器类型-->         <serverTypes>             <addname="TelnetServerType"type="LibSocketServer.Server.TelnetServer,LibSocketServer"/>         </serverTypes>     </superSocket> </configuration> 最后，创建控制台项目TelnetServerSample，添加项目引用LibSocketServer，然后在Program类中使用SocketServerManager进行SuperSocket的调用。

Program.cs

usingSystem; usingLibSocketServer;   namespaceTelnetServerSample {     classProgram     {         staticvoidMain()         {             try             {                 //启动SuperSocket                 if(!SocketServerManager.Instance.Startup(2021))                 {                     Console.WriteLine("FailedtostartTelnetServer!");                     Console.ReadKey();                     return;                 }                   Console.WriteLine("TelnetServerislisteningonport2021.");                 Console.WriteLine();                 Console.WriteLine("Presskey'q'tostopit!");                 Console.WriteLine();                 while(Console.ReadKey().KeyChar.ToString().ToUpper()!="Q")                 {                     Console.WriteLine();                 }                   //关闭SuperSocket                 SocketServerManager.Instance.Shutdown();             }             catch(Exceptione)             {                 Console.WriteLine("Exception:{0}",e.Message);             }               Console.WriteLine();             Console.WriteLine("TelnetServerwasstopped!");             Console.WriteLine("Pressanykeytoexit...");             Console.ReadKey();         }     } }
