Remove a Member from a PowerShell Object?

Question

I need to remove a member (specifically, a NoteProperty) from an object. How do I accomplish this?

Answer 1

Select-Object with ExcludeProperty is good for removing a property from a collection of objects.

For removing a property from a single object this method might be more effective:

# new object with properties Test and Foo
$obj = New-Object -TypeName PSObject -Property @{ Test = 1; Foo = 2 }

# remove a property from PSObject.Properties
$obj.PSObject.Properties.Remove('Foo')
