One of the neat tricks is write out what Methods, Properties get-member cmdlet. Here are a couple of replies I recently from my question in the Powershell newsgroup.
Example 1
————-
It works well for static methods (note the parenthesis and square brackets
around the class name):
PS> get-member -in ([system.math]) -static
Example 2
————-
You don't need to assign to a variable. You can pipe the new object into the get-member call:
new-object text.stringBuilder | get-member -memberType methods
If you don't want to create an instance at all, you can use reflection:
[text.stringBuilder].getMethods() | % { $_.name } | sort -unique
