OK, I'm losing it. PowerShell is annoying me. I'd like a pause dialog to appear, and it won't.
PS W:\>>> $host.UI.RawUI.ReadKey("NoEcho,IncludeKeyDown")
Exception calling "ReadKey" with "1" argument(s): "The method or operation is not implemented."
At line:1 char:23
+ $host.UI.RawUI.ReadKey <<<< ("NoEcho")
+ CategoryInfo : NotSpecified: (:) [], MethodInvocationException
+ FullyQualifiedErrorId : DotNetMethodException
10 years later i came here.... Don't know since when, but "pause" works in PowerShell like it did in DOS-commandline.
You may want to use FlushInputBuffer to discard any characters mistakenly typed into the console, especially for long running operations, before using ReadKey:
Write-Host -NoNewLine 'Press any key to continue...'
$Host.UI.RawUI.FlushInputBuffer()
$Host.UI.RawUI.ReadKey('NoEcho,IncludeKeyDown') | Out-Null
If you want to add a timer to the press any key, this works in PS 5.1:
$i=1
while (
!([Console]::KeyAvailable) -and
($i -le 10)
) {
sleep 1
Write-Host “$i..” -NoNewLine
$i++
}
Note that the KeyAvailable method for the c# $Host.UI.RawUI is currently bugged in a number of PS versions after PS 2 or 3.
One-liner for PS-ISE in option <5> in Michael Sorens' answer:
[Void][Windows.Forms.MessageBox]::Show("Click OK to continue.", "Script Paused")
