WMI重启远程计算机

我在一个旧线程上找到了这个代码来关闭本地机器:

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,我更希望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,但这是一个例子,我想出了使用MSDN和WMI Code Creator(顺便说一句,这是一个生成WMI代码的优秀工具,并支持C#等).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);
    }
}

作为参考,"Flags"值为2将此关闭请求转换为重启.这里有完整的标志列表:https://msdn.microsoft.com/en-us/library/aa394058(v = vs.85).aspx
