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)
{

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 < 1)
{
throw new Exception("不能打开服务管理器.");
}
iSCManagerLockHandle = modAPI.LockServiceDatabase(iSCManagerHandle);
if (iSCManagerLockHandle < 1)
{
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 < 1)
{

}

bChangeServiceConfig2 = modAPI.ChangeServiceConfig2A(iServiceHandle,
modAPI.InfoLevel.SERVICE_CONFIG_DESCRIPTION,ref ServiceDescription);
if (bChangeServiceConfig2==false)
{
throw new Exception("不能进行服务描述更改.");
}
ServiceFailureActions.dwResetPeriod = 600;
ServiceFailureActions.lpRebootMsg = "服务启动失败! 重启中...";
// ServiceFailureActions.lpCommand = "SomeCommand.exe Param1 Param2";

iScActionsPointer = Marshal.AllocHGlobal(Marshal.SizeOf(new modAPI.SC_ACTION()) * 3);
modAPI.CopyMemory(iScActionsPointer, ScActions, Marshal.SizeOf(new modAPI.SC_ACTION()) * 3);
ServiceFailureActions.lpsaActions = iScActionsPointer.ToInt32();
bChangeServiceConfig2 = modAPI.ChangeServiceConfig2A(iServiceHandle,
modAPI.InfoLevel.SERVICE_CONFIG_FAILURE_ACTIONS,ref ServiceFailureActions);
if (bChangeServiceConfig2==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 > 0)
{
bCloseService = modAPI.CloseServiceHandle(iServiceHandle);
}
if (iSCManagerLockHandle > 0)
{
bUnlockSCManager = modAPI.UnlockServiceDatabase(iSCManagerLockHandle);
}
if (iSCManagerHandle != 0)
{
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
Committed事件，在这里可以将安装的服务进行调整到运行状态
BeforeUninstall事件，您可以在这里将服务自动卸载掉 |
