This idiosyncrasy of PowerShell has frustrated me from day 1 of PS 2.0

When the variable is expanded, whether to use double or single quotes, curly braces etc.

The syntax of a language should not have such subtle differences, otherwise just use English. It has enough ambiguity for anyone 🙂

I agree, Ray. PoSh was supposed to be logical and make more sense than Bash, etc. Instead, there are some silly items like this, and like -eq and -ne rather than respecting = or ==.

Actually, this makes perfect sense to me. The CreationTime is a property of the $directory object. In the quoted string, $directory.CreationTime cannot be determined because the parser doesn't recognize it as a simple data value. To get what you want you should do something like this:

$directory = Get-Item 'C:\Program Files\Microsoft SQL Server'

$dTime = $directory.CreationTime

$message = "SQLDirectory Creation: $dTime"

This works because $dTime is a simple data value.

The problem is that Powershell recognizes $directory and parses its default value and then concatenates the rest of the string. To force an evaluation of the object property you can do this:

$message = "SQLDirectory Creation: $($directory.CreationTime)";
