[英]WMI to reboot remote machine
我在舊線程上找到了以下代碼以關閉本地計算機:
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);
}
}
是否可以使用類似的WMI方法重新啟動遠程計算機的標志“ 2”,對於該計算機我僅具有計算機名稱,而沒有IP地址。
編輯: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);
}
但這是行不通的,我希望WMI向前發展。
要將WMI查詢尋址到遠程計算機,只需在ManagementScope
對象中指定該計算機的名稱(或IP地址)。
我對C#不太了解,但這是我使用MSDN和WMI Code Creator提出的一個示例(順便說一句,這是生成WMI代碼的出色工具,並支持C#)。 希望這段代碼能給您帶來靈感。
( 免責聲明:此代碼未經測試。)
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);
}
}
我對此也有麻煩。 WMI可能會誤導類和對象的方法。 我的解決方案是使用C#和WMI重新啟動網絡上的主機,但對於本地計算機卻很容易簡化:
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解決方案,則可以使用shutdown命令。
shutdown [{-l|-s|-r|-a}] [-f] [-m [\\ComputerName]] [-t xx] [-c "message"] [-d[u][p]:xx:yy]
使用-m關閉遠程計算機。

這將像sharm一樣工作
gwmi win32_operatingsystem -ComputerName xxxxxxxxxxxx | Invoke-WmiMethod -Name reboot
