最近应客户的要求，做了一个定时监控WINDOWS服务的程序，要做到随机启动，定时监控指定的服务，如果没有开启则开启，由于时间仓促，没有经过长时间的服务器端运行，现将思路及代码公布，以后有改进会及时更新：
一、思路：
本程序的核心在于随机启动和WINDOWS服务上，对于随机启动，引入Microsoft.Win32命名空间，利用RegistryKey类即可完成对注册表的增、删、改等操作；对于WINDOWS服务，引入System.ServiceProcess命名空间，利用ServiceController类即可完成对系统服务的启动、停止、查询等操作。改日就测试程序的稳定性及资源消耗率等指标。
二、代码如下，这里程序默认为开启MSSQLSERVER服务，并添加了托盘区图标，可以在启动时或启动后最小化到托盘区：
