如何用c#开发系统服务.doc

如何用c# 开发系统服务最近用.net开发了个隔时执行的小应用程序，登录MSDTC，放到服务器，运转良好，退出远程桌面，事情出来了，那个可爱的程序不运作了，然后我就搞了个任务计划，做了下，以为完事了，过了一些时间，发现不对劲，还是停止执行程序了，上去一看，又停止了，这时候我不得不重新考虑设置，还是写个系统服务就去吧，写上一段代码先写个服务再说。using System;using System.Collections;using System.ComponentModel;using System.Diagnostics;using System.ServiceProcess;using System.Configuration.Install;namespace CjjerTest.DotNet.ServiceDST / 应用程序 public class MyFirstService : System.ServiceProcess.ServiceBase public MyFirstService() this.CanPauseAndContinue = true; this.CanShutdown = true; this.CanHandleSessionChangeEvent = false; this.ServiceName = MyFirstService; protected override void OnStart(string args) protected override void OnStop() protected override void OnContinue() /启动 public static void Main() ServiceBase servicesToRun = new ServiceBase new MyFirstService(); ServiceBase.Run(servicesToRun); /安装 RunInstaller(true) public class ProjectInstaller : System.Configuration.Install.Installer private ServiceProcessInstaller myServiceProcessInstaller; private ServiceInstaller myServiceInstaller; public ProjectInstaller() this.myServiceProcessInstaller = new ServiceProcessInstaller(); this.myServiceInstaller = new ServiceInstaller(); / 安装 / 用户名 和 密码 this.myServiceProcessInstaller.Account = ServiceAccount.LocalSystem; this.myServiceProcessInstaller.Username = null; this.myServiceProcessInstaller.Password = null; / 服务名称，这样可以在net stop XX 里面使用了 / 启动类型 this.myServiceInstaller.ServiceName = MyFirstService; this.myServiceInstaller.StartType = ServiceStartMode.Automatic; / 加入 this.Installers.AddRange(new Installer this.myServiceProcessInstaller, this.myServiceInstaller); 其中在启动的代码中我们可以执行： protected override void OnStart(string args) StreamWriter sw=new StreamWriter(E:webwebnettestsernet.txt,true); sw.Write(rn另一条数据); sw.Close(); base.OnStart( args ); 或者创建另一条线程执行其他程序。1、编译 csc cservice.cs 2、安装 installutil cservice.exe 3、启动服务 net start MyFirstService 4、停止服务 net stop MyFirstService 5、卸载 installutil /u cservice.exe上次我专门说明了如何用c# 开发系统服务，由于很多时候installutil.exe这个工具用起来还是有点繁琐，一直想着用c#代码自己完成启动服务，删除服务的操作。这就需要调用.NET的DllImport，主要是调用advapi32.dll这个dll来实现。 关于advapi32.dll的接口，有兴趣的可以查。我这里就写出实现的C#代码。using System;using System.Runtime.InteropServices;namespace MyServiceInstallerclass ServiceInstallerpublic static string AppPathgetreturn System.Environment.CurrentDirectory;#region Private Variables/private string _servicePath;/private string _serviceName;/private string _serviceDisplayName;#endregion Private Variables#region DLLImportDllImport(advapi32.dll)public static extern IntPtr OpenSCManager(string lpMachineName,string lpSCDB, int scParameter);DllImport(Advapi32.dll)public static extern IntPtr CreateService(IntPtr SC_HANDLE,string lpSvcName,string lpDisplayName, int dwDesiredAccess,int dwServiceType,int dwStartType,int dwErrorControl,string lpPathName, string lpLoadOrderGroup,int lpdwTagId,string lpDependencies,string lpServiceStartName,string lpPassword);DllImport(advapi32.dll)public static extern void CloseServiceHandle(IntPtr SCHANDLE);DllImport(advapi32.dll)public static extern int StartService(IntPtr SVHANDLE,int dwNumServiceArgs,string lpServiceArgVectors);DllImport(advapi32.dll,SetLastError=true)public static extern IntPtr OpenService(IntPtr SCHANDLE,string lpSvcName,int dwNumServiceArgs);DllImport(advapi32.dll)public static extern int DeleteService(IntPtr SVHANDLE);DllImport(kernel32.dll)public static extern int GetLastError();#endregion DLLImport/ / 应用程序入口./ STAThreadstatic void Main(string args) int ExeId = (args=null)?0:0;
