C#启动指定的Windows信使服务，本例中是启动IIS服务，在Windows XP下可完美运行，在Windows7下不行好像，本程序演示如何在C#的程序中启动一个指定的Windows内置服务的方法。具体的实现代码： 　　ServiceController service = new ServiceController();//创建服务控制对象 　　service.ServiceName = "Messenger";//启动Windows信史服务 　　//判断当前服务状态 　　if (service.Status == ServiceControllerStatus.Stopped) 　　{ 　　 try 　　 { 　　 service.Start();// 启动服务 　　 service.WaitForStatus(ServiceControllerStatus.Running); 　　 } 　　 catch (InvalidOperationException) 　　 { 　　 MessageBox.Show("不能启动该服务！"); 　　 } 　　}

哲学家进餐问题，进程是独立参与分配资源的最小单位，在有线程的OS中，线程是运行的最小单位， 课堂所述进程之间的同步与互斥，实际上是属于不同进程的线程间的同步与互斥，当 然，属于同一进程的不同线程一样存在同步与互斥，其控制同步与互斥的原理跟进程 是一样的-dining philosophers problem, the process is independent participation in the allocation of resources as the smallest unit, in the OS thread, thread is the smallest unit of operation, the process described in the classroom between the synchronization and mutual exclusion. actually belong to different threads in the process of synchronization and mutual exclusion, of course, the same process there is a different thread synchronization and mutual exclusion, control and coordinate the process with the principle of the same
