Count Paired Items with PowerShell

This is just a code fragment for something that took me some time to figure out.  What I wanted to do is to count a pair of items.  The data was coming from a CSV file, and one of the two values is calculated.

The code is:

#Make arrays the lazy way, splitting string
$UserList = "Shari,Richard,Alan".Split(",")
$PCList = "Comp1,Comp2,Comp3,Comp4".Split(",")

#Do this 100 times
$List = (1 ..100) |
    foreach  {
    #Get Random PC and User Name
    $PCName = Get-Random $PCList
    $UserName = Get-Random $UserList
    #Put them into a PSCustomObject
    [PSCustomObject]@{"PCName"=$PCName;"UserName"=$UserName}
    }

#Take the List, Group by PCName and Username, Sort ...
$List | group -Property PCName, UserName |
sort -Property name |
#This converts 'name' to Logons in display and gets count property added by Group
Select @{Label="Logons";Expression={$_.name}}, count | 
ft -AutoSize
									

If you run the code, you will get results like this:

Logons	Count
Comp1, Alan	9
Comp1, Richard	11
Comp1, Shari	8
Comp2, Alan	10
Comp2, Richard	8
Comp2, Shari	5
Comp3, Alan	3
Comp3, Richard	6
Comp3, Shari	9
Comp4, Alan	11
Comp4, Richard	10
Comp4, Shari	10
