高手进阶：给WINDOWS服务加上描述

   当我们创建一个WINDOWS服务后 却发觉我们所创建的服务没有相关的描述 （你可以打开服务管理器程序查看） 而System ServiceProcess ServiceBase这些相关的类都没有提供这方面的信息 同样如果我们需要给我们的服务加上恰当的描述 我们也只能通过非托管代码来处理

当我们给服务增加安装包时 我们可以在ProjectInstaller里加上我们修改服务描述的代码

private void InitializeComponent()  {

//这里要增加代码this AfterInstall += new System Configuration Install InstallEventHandler(this ProjectInstaller_AfterInstall)

}

private void ProjectInstaller_AfterInstall(object sender System Configuration Install InstallEventArgs e)  {

int iSCManagerHandle =    int iSCManagerLockHandle =    int iServiceHandle =    bool bChangeServiceConfig = false   bool bChangeServiceConfig = false   modAPI SERVICE_DESCRIPTION ServiceDescription   modAPI SERVICE_FAILURE_ACTIONS ServiceFailureActions   modAPI SC_ACTION[] ScActions = new modAPI SC_ACTION[ ]

bool bCloseService = false   bool bUnlockSCManager = false   bool bCloseSCManager = false

IntPtr iScActionsPointer = new IntPtr()

try   {    //打开服务控制台    iSCManagerHandle = modAPI OpenSCManagerA(null null      modAPI ServiceControlManagerType SC_MANAGER_ALL_ACCESS)

    if (iSCManagerHandle <)    {     throw new Exception( 不能打开服务管理器 )    }

    iSCManagerLockHandle = modAPI LockServiceDatabase(iSCManagerHandle)

    if (iSCManagerLockHandle <)    {     throw new Exception( 不能锁定服务管理器 )    }

//服务名    iServiceHandle = modAPI OpenServiceA(iSCManagerHandle JadeWatchService      modAPI ACCESS_TYPE SERVICE_ALL_ACCESS)

    if (iServiceHandle <)    {     throw new Exception( 不能打开服务进行修改 )    }        bChangeServiceConfig = modAPI ChangeServiceConfigA(iServiceHandle      modAPI ServiceType SERVICE_WIN _OWN_PROCESS | modAPI ServiceType SERVICE_INTERACTIVE_PROCESS      modAPI SERVICE_NO_CHANGE modAPI SERVICE_NO_CHANGE null null      null null null null)

    if (bChangeServiceConfig==false)    {     throw new Exception( 不能改变服务设置 )    }

    ServiceDescription lpDescription = 青鸟文件监控服务 如果停止该服务 数据将不能正常进行备份!

bChangeServiceConfig = modAPI ChangeServiceConfig A(iServiceHandle      modAPI InfoLevel SERVICE_CONFIG_DESCRIPTION ref ServiceDescription)

    if (bChangeServiceConfig ==false)    {     throw new Exception( 不能进行服务描述更改 )    } 

    ServiceFailureActions dwResetPeriod =     ServiceFailureActions lpRebootMsg = 服务启动失败! 重启中     // ServiceFailureActions lpCommand = SomeCommand exe Param Param     ServiceFailureActions lpCommand =     ServiceFailureActions cActions = ScActions Length

//故障恢复设置 这里没有设置    ScActions[ ] Delay =     ScActions[ ] SCActionType = modAPI SC_ACTION_TYPE SC_ACTION_NONE//不要对失败 *** 作做任何处理 如果重启服务等    ScActions[ ] Delay =     ScActions[ ] SCActionType = modAPI SC_ACTION_TYPE SC_ACTION_NONE    ScActions[ ] Delay =     ScActions[ ] SCActionType = modAPI SC_ACTION_TYPE SC_ACTION_NONE

    iScActionsPointer = Marshal AllocHGlobal(Marshal SizeOf(new modAPI SC_ACTION()) * )

    modAPI CopyMemory(iScActionsPointer ScActions Marshal SizeOf(new modAPI SC_ACTION()) * )

ServiceFailureActions lpsaActions = iScActionsPointer ToInt ()

    bChangeServiceConfig = modAPI ChangeServiceConfig A(iServiceHandle      modAPI InfoLevel SERVICE_CONFIG_FAILURE_ACTIONS ref ServiceFailureActions)

    if (bChangeServiceConfig ==false)    {     throw new Exception( 不能设置服务的故障恢复设置 )    }       }   catch(Exception ex)   {        throw new Exception(ex Message)   }   finally   {        Marshal FreeHGlobal(iScActionsPointer)

if (iServiceHandle >)    {     bCloseService = modAPI CloseServiceHandle(iServiceHandle)    }

if (iSCManagerLockHandle >)    {     bUnlockSCManager = modAPI UnlockServiceDatabase(iSCManagerLockHandle)    }

if (iSCManagerHandle != )    {     bCloseSCManager = modAPI CloseServiceHandle(iSCManagerHandle)    }   }     }

在安装完成后 我们对服务进行 这里可以修改的内容包括服务的描述 服务的故障处理等

如果你在安装时 需要对服务进行自动处于运行状态 或卸载时需要自动将服务也卸载 你只要注册

this beforeuninstall+=new InstallEventHandler(ProjectInstaller_BeforeUninstall)   this Committed+=new InstallEventHandler(ProjectInstaller_Committed)

这二个事件

mitted事件 在这里可以将安装的服务进行调整到运行状态

Service项目中最少要有两个组件类，一个组件类A 继承ServiceBase（Windows服务类），另一个组件类B 继承Installer（安装程序类），B中要有两个组件：System.ServiceProcess.ServiceProcessInstaller和System.ServiceProcess.ServiceInstaller,在ServiceInstaller的Description中填写服务的描述，DisplayName中填写在services.msc中显示的友好名称，ServiceName填写服务名，会在ServiceProcessInstaller被调用。在WMI遍历时也是以这个服务名为准。
