Question

我尝试编写一个简短的runas-admin函数，我可以将另一个函数名作为参数传递，并使用admin权限执行该命令（或多或少相当于linux中的sudo）。当我尝试运行该函数时，它会持续运行并且永远不会结束，占用了大量的cpu。我是PowerShell的新手，所以我的代码有问题吗？

function runas-admin
{
# Get the ID and security principal of the current user account
$myWindowsID=[System.Security.Principal.WindowsIdentity]::GetCurrent()
$myWindowsPrincipal=new-object System.Security.Principal.WindowsPrincipal($myWindowsID)

# Get the security principal for the Administrator role
$adminRole=[System.Security.Principal.WindowsBuiltInRole]::Administrator

# Check to see if we are currently running "as Administrator"
if ($myWindowsPrincipal.IsInRole($adminRole))
{
   # We are running "as Administrator" - so change the title and background color to indicate this
   $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)"
   $Host.UI.RawUI.BackgroundColor = "DarkBlue"
   clear-host
}
else
{
   # We are not running "as Administrator" - so relaunch as administrator

   # Create a new process object that starts PowerShell
   $newProcess = new-object System.Diagnostics.ProcessStartInfo "PowerShell";
   $newProcess.RedirectStandardError = $TRUE;
   $newProcess.RedirectStandardOutput = $TRUE;
   $newProcess.UseShellExecute = $FALSE;
   # Specify the current script path and name as a parameter
   $newProcess.Arguments = $myInvocation.MyCommand.Definition;

   # Indicate that the process should be elevated
   $newProcess.Verb = "runas";

   # Start the new process
   $childProcess = [System.Diagnostics.Process]::Start($newProcess);
   $childProcess.WaitForExit();
   Write-Output $childProcess.StandardOutput.ReadToEnd();
}
}

或者您可以使用动词Start-Process运行runas，例如：

Start-Process powershell.exe -Verb runas

如何在PowerShell中使用当前shell中的管理员权限运行命令？
