自提升脚本+执行策略

Question

我试图使用以下代码从问题"PowerShell:运行命令作为管理员"不仅自我提升我的脚本在管理员级PowerShell中自动运行，而且对于管理员级PowerShell会话以RemoteSigned的ExecutionPolicy级别运行。我假设我需要在$newProcess.Arguments中使用类似-ExecutionPolicy RemoteSigned的东西，但我完全失去了如果是这种情况，如果是的话，那么我用什么语法来创建多个参数?

# 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
$adminRole = [System.Security.Principal.WindowsBuiltInRole]::Administrator;
# Check to see if we are currently running as an administrator
if ($myWindowsPrincipal.IsInRole($adminRole)) {
    # We are running as an administrator, so change the title and background colour to indicate this
    $Host.UI.RawUI.WindowTitle = $myInvocation.MyCommand.Definition + "(Elevated)";
    $Host.UI.RawUI.BackgroundColor = "DarkBlue";
    Clear-Host;
} else {
    # We are not running as an administrator, so relaunch as administrator
    # Create a new process object that starts PowerShell
    $newProcess = New-Object System.Diagnostics.ProcessStartInfo "PowerShell";
    # Specify the current script path and name as a parameter with added scope and support for scripts with spaces in it's path
    $newProcess.Arguments = "& '" + $script:MyInvocation.MyCommand.Path + "'"
    # Indicate that the process should be elevated
    $newProcess.Verb = "runas";
    # Start the new process
    [System.Diagnostics.Process]::Start($newProcess);
    # Exit from the current, unelevated, process
    Exit;
}
# Run your code that needs to be elevated here...
Write-Host -NoNewLine "Press any key to continue...";
$null = $Host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown");

$newProcess.Arguments确实是您添加相关参数的地方。但是，您可能希望通过参数-File运行脚本，而不是在隐式-Command参数中使用调用操作符(&)。

$newProcess = New-Object Diagnostics.ProcessStartInfo 'powershell.exe'
$newProcess.Arguments = '-ExecutionPolicy RemoteSigned -File "' +
                        $script:MyInvocation.MyCommand.Path + '"'
$newProcess.Verb = 'runas'
[Diagnostics.Process]::Start($newProcess)
