I've recently started answering questions over at PowerShell.com, and a great one came in this morning:
I was recently writing a script to process some data from a CSV file using Import-CSV. I was having an issue so I went out and looked for an example that I could use. The example I found used syntax that I haven't seen explained but seems to be used frequently and I was hoping you could explain. I've simplified the example as it really is the syntax that throws me.
What is with the "$()" syntax wrapping the column1 value as both methods seem to work just fine?
foreach($Line in $CSVFile)
$Column1 = "$($line.Column1)"
$Column2 = $line.Column2
