我发现这个code在一个古老的线程来关闭本地计算机：

I found this code on an old thread to shutdown the local machine:

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);
    }
}

是否有可能使用类似的WMI方法重新启动标志2的远程计算机，为此我只有机器名，而不是ip地址。

Is it possible to use a similar WMI method to reboot flag "2" a remote machine, for which i only have machine name, not 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);
}

但是，这并不工作，我会preFER WMI向前发展。

but this doesn't work, and I would prefer WMI going forward.

推荐答案

要解决WMI查询到远程计算机，您只需在指定的计算机的名称（或IP地址）的ManagementScope对象。

To address WMI queries to a remote computer, you simply specify that computer's name (or IP address) in the ManagementScope object.

我没有很好地在C＃中，但这里有一个例子，我想出了利用MSDN和WMI code造物主（这是，顺便说一句，一个很​​好的工具，用于生成WMI code，并且支持C＃等等）。希望这code会给你的想法。

I'm not well up in C#, but here's an example I came up with using MSDN and WMI Code Creator (which is, by the way, an excellent tool for generating WMI code, and supports C# among others). Hope this code will give you the idea.

void Shutdown()

        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(

            // 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);
    }
