Answer 1

You can use Group-Object (alias group) to group everything by the Name property. Then you just need to sum up the Count property of each guy in the group. Measure-Object (alias measure) will do sums for you.

$grouped = Import-Csv .\csv1.csv, .\csv2.csv | group Name
$combined = $grouped |%{ 
   New-Object PsObject -Prop @{ Name = $_.Name; Count = ($_.Group | measure -sum -prop Count).Sum }
}
$combined | Export-Csv .\combined.csv -NoType
