It depends on what the provider implementation returns. In the FileSystem
provider the returned object for a container is a DirectoryInfo object. It
has a method called GetFileSystemInfos() which returns an array of its
children. So if you know you are in the file system you can do:
MSH > get-childitem . | foreach { if ($_ -is [System.IO.DirectoryInfo]) {
$_.GetFileSystemInfos().Length } }
or if you are in the registry you can use the SubKeyCount property:
MSH > get-childitem . | foreach { if ($_ -is [Microsoft.Win32.RegistryKey])
{ $_.SubKeyCount } }
You could even put the type in a switch statement and handle all the ones
you know about. My solution below will work for any provider regardless of
the type of object it returns.
