关于服务Service的操作

1.在使用ServiceController类前，我们必须引用命名空间System.ServiceProcess,而引用该命名空间，我们又必须在引用中添加System.ServiceProcess引用
2.ServiceController有两个名称，一个是DisplayName，一个是ServiceName,DisplayName-服务的友好名称，可用于标识该服务(就是我们在"控制面板"- >"服务"中看到的显示名称)ServiceName--服务进行标识的名称(这个才是服务的真正名称，也就是我们在"控制面板"- >"服务"中看到的服务名称)
3.ServiceController中其它一些有用的方法与属性：

Status属性：指示该服务现在是正在运行、已停止还是已暂停，或者启动、停止、暂停或继续命令被挂起
Pause()方法：暂停该服务。
Start()方法：启动该服务。
Stop()方法：停止该服务。
