The SettingChangingEventArgs type exposes the following members.

Public propertyCancelGets or sets a value indicating whether the event should be canceled. (Inherited from CancelEventArgs.)
Public propertyNewValueGets the new value being assigned to the application settings property.
Public propertySettingClassGets the application settings property category.
Public propertySettingKeyGets the application settings key associated with the property.
Public propertySettingNameGets the name of the application setting associated with the application settings property.

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

The SettingChangingEventArgs class provides data for the SettingChanging event, which signals that the value of an application settings property is about to change. The most common source for this event is the get accessor of the Item method in the ApplicationSettingsBase class.

Because SettingChangingEventArgs is derived from CancelEventArgs, the handler has the option of canceling the write operation.
