How to retrieve CSV file headers using PowerShell?

To retrieve the CSV file headers using PowerShell, we need to use the hidden property PSObject once we use to import the CSV file. We have a CSV file stored at the C:\temp\VMTags.csv and we need to retrieve its headers. The CSV file is as below.

Importing the CSV file,

PS C:\> $csv = Import-Csv C:\Temp\VMTags.csv
PS C:\> $csv
