WMI重启远程计算机

我在旧线程上发现此代码以关闭本地计算机:

using System.Management; void Shutdown() { ManagementBaseObject mboShutdown = null; ManagementClass mcWin32 = new ManagementClass("Win32_OperatingSystem"); mcWin32.Get(); // You can't shutdown without security privileges mcWin32.Scope.Options.EnablePrivileges = true; ManagementBaseObject mboShutdownParams = mcWin32.GetMethodParameters("Win32Shutdown"); // Flag 1 means we want to shut down the system. Use "2" to reboot. mboShutdownParams["Flags"] = "1"; mboShutdownParams["Reserved"] = "0"; foreach (ManagementObject manObj in mcWin32.GetInstances()) { mboShutdown = manObj.InvokeMethod("Win32Shutdown", mboShutdownParams, null); } } 

是否可以使用类似的WMI方法重启标志“2”远程机器,我只有机器名,而不是IPaddress。

编辑:我目前有:

 SearchResultCollection allMachinesCollected = machineSearch.FindAll(); Methods myMethods = new Methods(); string pcName; ArrayList allComputers = new ArrayList(); foreach (SearchResult oneMachine in allMachinesCollected) { //pcName = oneMachine.Properties.PropertyNames.ToString(); pcName = oneMachine.Properties["name"][0].ToString(); allComputers.Add(pcName); MessageBox.Show(pcName + "has been sent the restart command."); Process.Start("shutdown.exe", "-r -f -t 0 -m \\" + pcName); } 

但这不起作用,我宁愿WMI继续前进。

要解决对远程计算机的WMI查询,只需在ManagementScope对象中指定该计算机的名称(或IP地址)即可。

我在C#中表现不佳,但这是我用MSDN和WMI Code Creator (这是一个生成WMI代码的优秀工具,并支持C#等)的一个例子。 希望这段代码能给你这个想法。

免责声明:此代码未经测试。)

 using System; using System.Management; ... void Shutdown() { try { const string computerName = "COMPUTER"; // computer name or IP address ConnectionOptions options = new ConnectionOptions(); options.EnablePrivileges = true; // To connect to the remote computer using a different account, specify these values: // options.Username = "USERNAME"; // options.Password = "PASSWORD"; // options.Authority = "ntlmdomain:DOMAIN"; ManagementScope scope = new ManagementScope( "\\\\" + computerName + "\\root\\CIMV2", options); scope.Connect(); SelectQuery query = new SelectQuery("Win32_OperatingSystem"); ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query); foreach (ManagementObject os in searcher.Get()) { // Obtain in-parameters for the method ManagementBaseObject inParams = os.GetMethodParameters("Win32Shutdown"); // Add the input parameters. inParams["Flags"] = 2; // Execute the method and obtain the return values. ManagementBaseObject outParams = os.InvokeMethod("Win32Shutdown", inParams, null); } } catch(ManagementException err) { MessageBox.Show("An error occurred while trying to execute the WMI method: " + err.Message); } catch(System.UnauthorizedAccessException unauthorizedErr) { MessageBox.Show("Connection error (user name or password might be incorrect): " + unauthorizedErr.Message); } } 

我也遇到了麻烦。 WMI可能会误导类和对象的方法。 我的解决方案是使用C#和WMI重新启动网络上的主机,但本地计算机很容易简化:

 private void rebootHost(string hostName) { string adsiPath = string.Format(@"\\{0}\root\cimv2", hostName); ManagementScope scope = new ManagementScope(adsiPath); // I've seen this, but I found not necessary: // scope.Options.EnablePrivileges = true; ManagementPath osPath = new ManagementPath("Win32_OperatingSystem"); ManagementClass os = new ManagementClass(scope, osPath, null); ManagementObjectCollection instances; try { instances = os.GetInstances(); } catch (UnauthorizedAccessException exception) { throw new MyException("Not permitted to reboot the host: " + hostName, exception); } catch (COMException exception) { if (exception.ErrorCode == -2147023174) { throw new MyException("Could not reach the target host: " + hostName, exception); } throw; // Unhandled } foreach (ManagementObject instance in instances) { object result = instance.InvokeMethod("Reboot", new object[] { }); uint returnValue = (uint)result; if (returnValue != 0) { throw new MyException("Failed to reboot host: " + hostName); } } } 

如果需要非WMI解决方案,可以使用shutdown命令。

 shutdown [{-l|-s|-r|-a}] [-f] [-m [\\ComputerName]] [-t xx] [-c "message"] [-d[u][p]:xx:yy] 

使用-m关闭远程计算机。

这将像沙姆一样工作

 gwmi win32_operatingsystem -ComputerName xxxxxxxxxxxx | Invoke-WmiMethod -Name reboot
