windows powershell display the current variable in the pipeline during a for each loop

Im deleting profiles using the get-wmi commandlet. As the code goes through each delete command in the loop I would like to display which profile is being deleted. I tried this:

$total = 0
$count = 1
foreach ($localpath in $dispaths)
{$total = $total + 1}
Foreach ($localpath in $dispaths) 
{cls
write-host "Deleting Profile: $_.localpath ($count of $total)"
$count = $count + 1
get-wmiobject -class win32_userprofile -computername $cname | where 
{$_.localpath -eq $localpath.localpath} | foreach {$_.Delete()}
}

but while the count works right, the display line shows literally:

Deleting Profile: ./localpath (1 of 135)

instead of displaying whatever the current string inside of the localpath variable is. I tried removing the . from $._localpath but that just displayed something like this:

Deleting Profile: (1 of 135)

it doesnt display anything where the variable string should be. Where am I going wrong?

The loop is a ForEach loop not a ForEach-Object. So you need to use the variable defined in the ForEach Statement.

Your Foreach:

Foreach ($localpath in $dispaths)

So you'll need to properties on the variable $localpath not $_

write-host "Deleting Profile: $_.localpath ($count of $total)"

would become:

write-host "Deleting Profile: $($Localpath.localpath) ($count of $total)"

Note that this is different from your final line, as your are using foreach as the alias for ForEach-Object. So your line could more precisely written as:

Get-WMIObject -Class Win32_UserProfile -ComputerName $cname | 
    Where-Object {$_.localpath -eq $localpath.localpath} |
    ForEach-Object {$_.Delete()}

So since this is line uses ForEach-Object and the pipeline you use $_ for the values pass down the pipeline. But also uses $localpath from the parent ForEach loop.
