当我们创建一个WINDOWS服务后却发觉我们所创建的服务没有相关的描述（你可以打开服务管理器程序查看）而SystemServiceProcessServiceBase这些相关的类都没有提供这方面的信息同样如果我们需要给我们的服务加上恰当的描述我们也只能通过非托管代码来处理 using System; using SystemRuntimeInteropServices; namespace FileWatchService { public class modAPI { [DllImport(advapidll)] public static extern int LockServiceDatabase(int hSCManager);
