Remove Second Row From CSV

Question

I've got a group of small CSV files - only about 15 and with about 30 rows each in. I'm running a script against them once a month so because they're so small and being processed infrequently they can read-in and treated as a string. I need to remove the
second row of the file though and I've got nowhere with it so far.
Sample data:
TimeIndex,CPU,FCP,NFS,CIFS,ISCSI,NetworkIn,NetworkOut,NetworkTotal,Filername
TimeIndex,CPU,FCP,NFS,CIFS,ISCSI,NetworkIn,NetworkOut,NetworkTotal,000-samplehostname
So the header is correct, but the sample hostname on the second row would be different for each file and that row shouldn't be there. The simplest thing to do is just wipe that row entirely.
Any ideas?
Thanks in advance

I have two ideas :-)
You mentioned that you are just reading in the files and treating them as strings.  In this case, you'd want to split it to a collection of objects and remove the second row...like this:
$strMultiLineString = "Test
Test
Test"
$arrlines = {$strMultiLineString -split "`r"}.INvoke() #Force it into an object collection
$null = $arrlines.Remove($arrlines[1])
If you are importing the file as a csv, you could do something like this:
$csv = {Import-CSV -path "C:\Temp\Test.csv"}.Invoke()
$null = $csv.Remove($csv[1])
Here is more information on adding and removing items from arrays/collections:

That should remove the line in question, but is only done in memory, sounds to me the OP wants it removed from the file, so you would need to save the changes back to the actual file
