Gets the application settings key associated with the property.
Assembly: System (in System.dll)
Each settings wrapper class, derived from ApplicationSettingsBase, has an associated settings key, which is a string that helps disambiguate different instances of the same wrapper in a single application. Because each wrapper class defines a set of properties that represent application settings, the settings key can similarly help disambiguate their use.
