C# WMI 权限

Question

我搜索了许多关于如何将 VBS 转换为 C# 以及所有这些好东西的问题。

我遇到的问题是，当进程在其运行的远程计算机上执行时，VBS 代码（见下文）使用系统帐户。
当我使用 C# 执行时，它会使用我的凭据（或运行 C# 程序的任何人）运行。
VBS 似乎在远程安装方面更可靠，这正是我所需要的。

我想切换到 C#，这样我就可以为程序制作一个更加用户友好的 GUI。
有人知道如何让 C# 使用 SYSTEM 帐户运行 WMI 吗？

VBS代码：

Set objWMIService = GetObject("winmgmts:\\" & strComputer & "\root\cimv2")
Set objScheduledJob = objWMIService.Get("Win32_ScheduledJob")
Set objSWbemDateTime = CreateObject("WbemScripting.SWbemDateTime")

'add the scheduled job to be run
objSWbemDateTime.SetVarDate(DateAdd(INTERVAL, MINUTES, Now()))
errReturn = objScheduledJob.Create(strCommand, objSWbemDateTime.Value, False, 0, 0, True, intJobID)

C#代码：

static public int RemoteAdmin(string remoteMachine, string runFile)
{
    try
    {
        ManagementPath run = new ManagementPath(@"\\" + remoteMachine + @"\root\cimv2:Win32_process");
        ManagementClass man = new ManagementClass(run);

        man.InvokeMethod("Create", new Object[] { runFile });
        return 0;
    }
    catch
    {
        MessageBox.Show("Error in remote execution");
        return 1;
    }
}

Answer 1

您需要设置 ConnectionOptions

ConnectionOptions wmiConnOpts = new ConnectionOptions();
wmiConnOpts.Impersonation = ImpersonationLevel.Impersonate;
wmiConnOpts.Authentication = System.Management.AuthenticationLevel.Default;
wmiConnOpts.EnablePrivileges = true;

ManagementScope wmiLoc = 
   new ManagementScope(String.Format(@"\\{0}\root\cimv2", remoteMachine ),
      wmiConnOpts);
ManagementPath wmiProcPath = new ManagementPath("Win32_ScheduledJob");
ManagementClass wmiProc = new ManagementClass(wmiLoc, wmiProcPath, null);
wmiProc.InvokeMethod("Create", new Object[] { runFile });

Answer 2

这可能是我的白痴错误，但我收到的错误是因为我没有指定它启动计划作业的时间（UTC 格式）

    ConnectionOptions connOptions = new ConnectionOptions();
    connOptions.Impersonation = ImpersonationLevel.Impersonate;
    connOptions.Authentication = AuthenticationLevel.PacketPrivacy;
    connOptions.EnablePrivileges = true;
    ManagementScope manScope = new ManagementScope(String.Format(@"\\" + remoteMachine + @"\ROOT\CIMV2"), connOptions);
    manScope.Connect();
    ObjectGetOptions objectGetOptions = new ObjectGetOptions();
    ManagementPath managementPath = new ManagementPath("Win32_ScheduledJob");
    ManagementClass processClass = new ManagementClass(manScope, managementPath, objectGetOptions);
    ManagementBaseObject inParams = processClass.GetMethodParameters("Create");
    inParams["Command"] = runFile;
    string StartTime = DateTimetoUTC(DateTime.Now.AddMinutes(1));
    inParams["StartTime"] = StartTime;
    ManagementBaseObject outParams = processClass.InvokeMethod("Create", inParams, null);
