PSListModifier Generic Class
Provides Add, Remove, and Replace lists that can be used to update lists. This class is introduced in Windows PowerShell 2.0.
Namespace: System.Management.Automation Assembly: System.Management.Automation (in System.Management.Automation.dll)
This class is returned by the Update-List cmdlet. Other cmdlets that modify lists could also use this class to provide Add, Remove, and Replace lists.
This generic class provides a more descriptive syntax for those cmdlets that use a PSListModifier object. For example, in the following table the syntax for the command that uses the generic class (first row) explicitly indicates that a string is needed.
