The ValidateSet attribute specifies a set of possible values for a cmdlet parameter argument. This attribute can also be used by Windows PowerShell functions.

The ValidateSet attribute specifies a set of possible values for a cmdlet parameter argument. This attribute can also be used by Windows PowerShell functions.

When this attribute is specified, the Windows PowerShell runtime determines whether the supplied argument for the cmdlet parameter matches an element in the supplied element set. The cmdlet is run only if the parameter argument matches an element in the set. If no match is found, an error is thrown by the Windows PowerShell runtime.
