Vista - accessing the extended type system from C#

say i create a pipeline and run "dir c:\". i get returned a
Collection<PSobject> . from this i can get the baseobject for whether
its a fileinfo or directoryinfo etc.. however how can i get the
extended type system properties.. i.e the PSdrive, PSiscontainer etc
etc?

Karl

(bool)psobj.Properties["psiscontainer"].Value

seems to be the way.
no method to list the properties?

Well if psobj.Properties is a collection, you can probably enumerate the
key/value pairs.

Correct. You can use the properties collection to get all the properties,
the methods collection to get all the methods or just use the members
collection to get everything. This works from within PowerShell as well:

PS (116) > (ls)[0].psobject


Members : {PSPath, PSParentPath, PSChildName, PSDrive...}
Properties : {PSPath, PSParentPath, PSChildName, PSDrive...}
Methods : {get_Name, get_Parent, CreateSubdirectory, Create...}
ImmediateBaseObject : figures_appendix
BaseObject : figures_appendix
TypeNames : {System.IO.DirectoryInfo, System.IO.FileSystemInfo,
System.MarshalByRefObject
, System.Object}

woah... that a neat trick. its interesting because the psobject
properties doesn't show up in get-member i.e

(ls)[0] | gm doesn't show a psobject property

another supercool trick to add to the collection
