说明：  C#获取Windows系统服务信息，只需点击一下按钮，即可获取到系统的所有服务信息，不过只获取的系统名称，还可以获取指定的系统服务类型，初学者程序，高手就不要看了。
(C# for Windows system service information, simply click the button, you can get all the service information to the system, but only get the system name, you can also access the specified system service type, beginners program, experts do not read.)
