How to get status of “Invoke-Expression”, successful or failed?

Question

Invoke-Expression will return all the text of the command being invoked.

But how can I get the system return value of whether this command has been exec

Answer 1

I found a simple way to do it, which keeps STDOUT in tact.

$Expr="MY EXPRESSION"
$Expr += '; $Success=$?'
Invoke-Expression $Expr

Success is now True or False, and all IO remains intact.
