Posted 2021-05-22

# Get all possible values of variable of dynamic Enum type
$VerbosePreference.gettype().GetEnumValues()

# or if you start with name of type in string and you need to cast to that type explicitly:
$String = 'System.Management.Automation.ActionPreference'
$Value = 'SilentlyContinue'
$Value -As ($string -As [Type])
