You work as an application developer at Certkiller .com. You have been given the task of developing a Windows service application that regularly monitors other Windows services on the same computer. This Windows service application must also log any abnormal file system activity. You have added the following class to the Windows service application: public class EnumerateService : ServiceBase { public static EnumerateService () { this.ServiceName = "Enumerate Service"; this.CanStop = true; } protected override void OnStart (string[] args) { // Enumerate all services and initialize the FileSystemWatcher } protected override void OnStop () { // Stop the FileSystemWatcher and perform cleanup } public static void Main () { EnumerateService service = new EnumerateService(); } } You then create the installer for the Windows service application, and install the Windows service application. You have configured the Windows service Startup type to Automatic, and rebooted the system. You then test the new Windows service application, and find that it is not working.You need to ensure that the service is working properly. What should you do?()

第11题:
服务链接能够获取到Service对象,因此绑定Service的组件可以调用在Service中实现的函数。
使用Service的组件通过Context.bindService()建立服务链接,通过Context.stopService()或Service.stopSefl()停止服务链接。
如果在绑定过程中Service没有启动,Context.bindService()会自动启动Service。
同一个Service可以绑定多个服务链接,这样可以同时为多个不同的组件提供服务。
