Looping through a list of computers using Get-WmiObject

I have the attached script to go through many servers in the network and get their share information. Some computers in our network have different names in dns, ex I will query a computername called ComputerA and I will get back data related to ComputerA_New , because somebody changed the computername recently or so

• Currently I am getting column list from the query using "SELECT __Server, ..." query, is it possible for me to also get the passed in computername out as data to find the computer name mismatches?
• The other thing, I started an error handling as below but does not work as I expected. Even though I get multiple errors I can only print one of them., how can I print all the errors?
• And also I would like to link the input computername passed into the powershell script to the error output, I would like to know which computername inputted caused the error, can I do that?
• Also since the error output is long with multilines how can I have computername, errorid, errormessage exported in a format that I can import it back (not sure tab delimited csv export will work here?)

Thank you

$strFileName = "C:\Temp\ShareOut.txt"
IF (Test-Path $strFileName){
	Remove-Item $strFileName
}
Try
{
	Get-WmiObject Win32_Share -Filter "Type = 0" -computerName (Get-Content "C:\Temp\ServerList.txt").split(",",[StringSplitOptions]'RemoveEmptyEntries') -ErrorVariable myerror -ErrorAction SilentlyContinue | SELECT __SERVER, Caption, Description, Name, Path, Status | Export-Csv -Delimiter "`t" $strFileName
}
Catch
{
	Write-Host $myerror.count
	for ($index = 0; $index -lt $myerror.count; $index++)
	{
		Write-Host $myerror[$index].exception
	}
}
