使用C#检查在远程计算机上运行的服务的状态

我正在使用下面的代码。

ServiceController MyController = new ServiceController(); MyController.MachineName = server_txt.Text.Trim(); MyController.ServiceName = "Service1"; string msg = MyController.Status.ToString(); Label1.Text = msg; 

此代码适用于有权访问的networking计算机。 如何改变这个,使它适用于使用凭证的不同域中的系统?

如果您使用WMI,则可以在“ConnectionOptions”中设置凭据。

 ConnectionOptions op = new ConnectionOptions(); op.Username = "Domain\\Domainuser"; op.Password = "password"; ManagementScope scope = new ManagementScope(@"\\servername.Domain\root\cimv2", op); scope.Connect(); ManagementPath path = new ManagementPath("Win32_Service"); ManagementClass services; services = new ManagementClass(scope, path, null); foreach (ManagementObject service in services.GetInstances()) { if (service.GetPropertyValue("State").ToString().ToLower().Equals("running")) { // Do something } } 

MSDN是你的朋友。

 using System.ServiceProcess; ServiceController sc = new ServiceController("YourService", "MachineName"); if (sc.Status.Equals(ServiceControllerStatus.Stopped) || sc.Status.Equals(ServiceControllerStatus.StopPending) { // it is stopped } 

我知道,如果你在那台机器上拥有管理员权限,只需要上面的代码。 但是,如另一条评论所述,如果您正在运行的帐户在该计算机上没有管理员权限,则可能必须使用模拟进行设置,如下所示:

 string userName = "domain\\user"; // there's really just one slash, //but you have to escape it if hard-coding.. //if brought in by a text box, it would be just domain\user string password = "whatever"; WindowsImpersonationContext adminContext = Impersonation.getWic(userName, password); if (adminContext != null) { try { ServiceController sc = new ServiceController("YourService", "MachineName"); if (sc.Status.Equals(ServiceControllerStatus.Stopped) || sc.Status.Equals(ServiceControllerStatus.StopPending) { // it is stopped } } catch (Exception ex) { Console.Out.WriteLine("\nUnable to set profile to Mandatory:\n\t" + ex.Message); Impersonation.endImpersonation(); adminContext.Undo(); } finally { Impersonation.endImpersonation(); // The above line just basically does this on the tokens -- //if (tokenHandle != IntPtr.Zero) CloseHandle(tokenHandle); adminContext.Undo(); } } 

这是我单独的模拟类。 它有2个主要的入口点, getWic()doImpersonation()getWic()将采取一个用户名,看起来像domain\usermachinename\user并把它们分成他们的组成部分,然后交给doImpersonation()doImpersonation()接受已经分割的部分,如果你有这样的,并不需要getWic()的代码。 两者都返回一个WindowsImpersonationContext
