在cmd c#中运行PowerShell命令时出现错误

Question

我想在c#中执行以下命令:

@echo off
PowerShell "ForEach($v in (Get-Command -Name "Set-ProcessMitigation").Parameters["Disable"].Attributes.ValidValues){Set-ProcessMitigation -System -Disable $v.ToString() -ErrorAction SilentlyContinue}"
pause

我把它放在CMD文件中，并运行它:

Process.Start(CMDFilePath);

但是出现错误:

C:UsersNew-hwidDesktopDebug2>PowerShell "ForEach($v in (Get-Command -Name "Set-ProcessMitigation").Parameters["Disable"].Attributes.ValidValues){Set-ProcessMitigation -System -Disable $v.ToString() -ErrorAction SilentlyContinue}"
Get-Command : The term 'Set-ProcessMitigation' is not recognized as the name of a cmdlet, function, script file, or
operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try
again.

当我打开cmd文件正常工作，但当我运行它通过Process.Start(…)这个错误发生，我的操作系统是windows 10 64位，如何运行cmd文件没有错误?由于

Answer 1

，您看到的问题是由于文件系统重定向，这是因为您在64位操作系统上以32位运行程序。因此，您正在执行%windir%SysWOW64SystemPropertiesProtection.exe(例如:C:WindowsSysWOW64SystemPropertiesProtection.exe)。所以我添加In app.manifest，并替换

<requestedExecutionLevel level="asInvoker" uiAccess="false" />

<requestedExecutionLevel  level="requireAdministrator" uiAccess="false" />

并修改代码以使用powershell:

public static void OpenPowerShell(string Command)
{
try
{
string filename = System.IO.Path.Combine(Environment.GetEnvironmentVariable("windir"), "System32", "WindowsPowerShell","v1.0","powershell.exe");

//environment variable windir has the same value as SystemRoot
//use 'Sysnative' to access 64-bit files (in System32) if program is running as 32-bit process
//use 'SysWow64' to access 32-bit files on 64-bit OS
if (Environment.Is64BitOperatingSystem && !Environment.Is64BitProcess)
{
//filename = System.IO.Path.Combine(Environment.GetEnvironmentVariable("windir"), "SysNative", "PowerShell.exe");
filename =System.IO.Path.Combine(Environment.GetEnvironmentVariable("windir"), "SysNative", "WindowsPowerShell", "v1.0", "powershell.exe");
}


ProcessStartInfo startInfo = new ProcessStartInfo(filename);
startInfo.UseShellExecute = true;
startInfo.WorkingDirectory = System.IO.Path.GetDirectoryName(filename);
startInfo.Arguments = "-NoExit "+Command  ;
Process.Start(startInfo);
}
catch (Exception ex)
{
FRM_MSG f = new FRM_MSG();
f.ShowDLG(" ",
ex.Message + "n" + ex.StackTrace.ToString(),
FRM_MSG.MSGIcon.Error,
FRM_MSG.BTNS.One,
new string[] { "Ok" });
throw ex;
}
}
