     说明，其实一个服务的属性和方法除了上面这几个还有很多，我们可以通过实例化ManagementClass类，使用它的Properties属性和Methods属性列出所有的属性和方法。上面的Win32ServiceManager中生成的每个服务实例都是ManagementObejct类型的，其实还有一种强类型的类，可以通过编程和工具来生成。
     总结，通过引用System.Management命名空间，上面简单的实现了通过访问\root\cimv2:Win32_Service名称空间对服务进行显示和操作。此外，我们还可以通过访问其他名称空间来访问计算机的一些硬件信息，软件信息以及网络等，有兴趣的读者可以研究一下。
