You can use the combination of "Get-member" with "Out-File" to help you get the list of Methods and Properties of your collection of .NET (or COM) objects from your $x variable.  In the following sample, you create a variable $x.  The purpose is to have another way to access the list of methods and properties so you won't open another PowerShell session in order to get to it.  I think this is a practical way to do it.  This way you can get the list from a notepad editor so you can see what's available. 

Sample Code

PS> $x = 'TEST' PS> $x | gm | out-file -FilePath c:\temp\gm.txt ; ii c:\temp\gm.txt

Have fun!!
