19 WTSerInst = new ServiceInstaller ();
20 WTSerInst. StartType = ServiceStartMode. Automatic; // The Post-service startup mode (Automatic, Manual, and Disabled)
21 WTSerInst. ServiceName = "WriteTextService"; // The name of the service to be installed is the same as that of the service class

68 in this way, a service is completed with a service description, which is added by rewriting the parent class install and uninstall. Because the service has a description under HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/writetextservice, the description of the service should be added to this item, therefore, the install and uninstall methods are essentially the addition and deletion of registry English. Next, let's take a look at the service operations, that is, load, unload, start, and stop. We create a new web site with only one default. on the ASPX page, the Code is as follows: default. aspx 1 <% @ page Language = "C #" autoeventwireup = "true" codefile = "default. aspx.

67}
68}
69}
70 we load and unload services through the AssemblyInstaller class, and start and stop services through the ServiceController class. In this way, we will complete the services and control services. (My code is implemented under vista and vs2008 .)
