C#监控远程计算机的进程时间:2008-12-31 00:00来源: 作者: 点击: 39次由于公司服务器上的一些重要程序会因为异常而自动关闭,从而影响数据处理的工作进度,所以现在需要做一个应该程序,能在本地计算机监控远程计算机上的进程情况(间隔一段时间检查一下),这样就可以及时发现被关闭的程序.界面:主要源码如下: public class ProcessInfo / defenition of the delegatespublic delegate void StartedEventHandler(object sender, EventArgs e);public delegate void TerminatedEventHandler(object sender, EventArgs e);/ events to subscribepublic StartedEventHandler Started = null; public TerminatedEventHandler Terminated = null; / WMI event watcherprivate ManagementEventWatcher watcher;/ The constructor uses the application name like notepad.exe/ And it starts the watcherpublic ProcessInfo(string appName)/ querry every 2 secondsstring pol = 2; string queryString = Select * +FROM _InstanceOperationEvent + WITHIN + pol + Where TargetInstance ISA Win32_Process + AND TargetInstance.Name = + appName + ;/ You could replace the dot by a machine name to watch to that machinestring scope = .rootCIMV2;/ create the watcher and start to listenwatcher= new ManagementEventWatcher(scope, queryString);watcher.EventArrived += new EventArrivedEventHandler(this.OnEventArrived);watcher.Start();public void Dispose()watcher.Stop();watcher.Dispose();public static DataTable RunningProcesses()/* One way of constructing a querystring className = Win32_Process;string condition = ;string selectedProperties = new string Name, ProcessId, Caption, ExecutablePath;SelectQuery query = new SelectQuery(className, condition, selectedProperties);*/ The second way of constructing a querystring queryString = Select Name, ProcessId, Caption, ExecutablePath + FROM Win32_Process;SelectQuery query = new SelectQuery(queryString);ConnectionOptions options = new ConnectionOptions();options.Username = EquityUser;options.Password = GXy1q88E;ManagementScope scope = new System.Management.ManagementScope(szeqdata0rootCIMV2, options);scope.Connect();ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query);ManagementObjectCollection processes = searcher.Get();DataTable result = new DataTable();result.Columns.Add(Name, Type.GetType(System.String);result.Columns.Add(ProcessId, Type.GetType(System.Int32);result.Columns.Add(Caption, Type.GetType(System.String);result.Columns.Add(Path, Type.GetType(System.String);foreach(ManagementObject mo in processes)DataRow row = result.NewRow();rowName = moName.ToString();rowProcessId = Convert.ToInt32(moProcessId);if (moCaption!= null)rowCaption = moCaption.ToString();if (moExecutablePath!= null)rowPath = moExecutablePath.ToString();result.Rows.Add( row );return result; private void OnEventArrived(object sender, System.Management.EventArrivedEventArgs e)try string eventName = e.NewEvent.ClassPath.ClassName;if (eventName.CompareTo(_InstanceCreationEvent)=0)/ Startedif (Started!=null) Started(this, e);else if (eventName.CompareTo(_InstanceD
