我们写一个服务，有时候要让服务启动某个应用程序，就要修改服务的属性，勾选允许服务与桌面交互，
可以用修改注册表实现，我们必须在安装后操作，所以请重写Installer的OnAfterInstall。
protected override void OnAfterInstall(System.Collections.IDictionary savedState) { RegistryKey rk = Registry.LocalMachine; string key = @" SYSTEM/CurrentControlSet/Services/ " + this .sInstaller.ServiceName; RegistryKey sub = rk.OpenSubKey(key, true ); int value = ( int )sub.GetValue( " Type " ); if (value < 256 ) { sub.SetValue( " Type " , value | 256 ); } base .OnAfterInstall(savedState); }
但以上方法只能在重启后起到作用。。。若要想立即生效可以用以下代码代之，将此方法放入onAfterInstall即可
设置服务与桌面交互 private void SetServiceDesktopInsteract( string serviceName) { ManagementObject wmiService = new ManagementObject( string .Format( " Win32_Service.Name='{0}' " ,serviceName)); ManagementBaseObject changeMethod = wmiService.GetMethodParameters( " Change " ); changeMethod[ " DesktopInteract " ] = true ; ManagementBaseObject OutParam = wmiService.InvokeMethod( " Change " , changeMethod, null ); }
若想立即启动服务调System.ServiceProcess.ServiceController类来实现
