How to get Import-CSV to work for me

Hi,

I have a csv file with 5 columns, the first 3 columns are IPV4 IPs with the 4-6 columns just text.  My goal is to Import the CSV, convert to strings, then perform string comparisons using the first 3 columns against other variables.

The issue I'm seeing is an Import-Csv natively creates a PSCustomObject, so I perform the following to create the first column as a string, however this technique doesn't work for the other columns.

$header = "H1", "H2", "H3", "H4", "H5", "H6"

$Data=Import-Csv C:\Data.csv -Header $header | Select -Expand H1

I need the whole row or all columns to be string so I can use in my script for comparisons.  How can I do this?

Thanks for your help! SdeDot
