SpecialSettingAttribute Class

Indicates that an application settings property has a special significance. This class cannot be inherited.


Namespace:  System.Configuration
Assembly:  System (in System.dll)

public ref class SpecialSettingAttribute sealed : public Attribute

The SpecialSettingAttribute type exposes the following members.

Public methodSpecialSettingAttributeInitializes a new instance of the SpecialSettingAttribute class.

Public propertySpecialSettingGets the value describing the special setting category of the application settings property.
Public propertyTypeIdWhen implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute.)

Public methodEqualsInfrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
Public methodGetHashCodeReturns the hash code for this instance. (Inherited from Attribute.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodIsDefaultAttributeWhen overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
Public methodMatchWhen overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

Explicit interface implemetationPrivate method_Attribute::GetIDsOfNamesMaps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute::GetTypeInfoRetrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute::GetTypeInfoCountRetrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
Explicit interface implemetationPrivate method_Attribute::InvokeProvides access to properties and methods exposed by an object. (Inherited from Attribute.)

Certain application settings properties have a special significance that alters the way in which their associated settings provider should process them. The SpecialSettingAttribute is used to identify such properties. This class uses the System.Configuration::SpecialSetting enumeration to indicate what special category the property belongs to.

SpecialSettingAttribute can only be applied to the settings class or to the individual settings property.

For an example of how a settings provider deals with the SpecialSettingAttribute, see the GetPropertyValues method of the LocalFileSettingsProvider class.
