The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

Specifies the settings provider used to provide storage for the current application settings class or property. This class cannot be inherited.

Assembly:  System (in System.dll)


[AttributeUsageAttribute(AttributeTargets::Class | AttributeTargets::Property)]
public ref class SettingsProviderAttribute sealed : Attribute


Initializes an instance of the SettingsProviderAttribute class.


Initializes a new instance of the SettingsProviderAttribute class.


Gets the type name of the settings provider.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetIDsOfNames(Guid%, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::Invoke(UInt32, Guid%, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

Each application settings class defines a group of application settings properties that represent information that persists between executions of the application. However, it is a settings provider—a class derived from SettingsProvider—that actually provides the storage mechanism.

The SettingsProviderAttribute specifies the settings provider used to provide storage for application settings properties. This attribute can be applied to the entire application settings class or individual application settings properties. A SettingsProviderAttribute set at the property level will override the class-level attribute. If a settings provider is not explicitly specified, the default provider is used. For client applications, the default provider is LocalFileSettingsProvider.

Setting providers cannot be determined at run time. Any run-time determination of storage methods must be coded into the settings provider class itself.


Using custom settings providers from arbitrary third parties is inherently unsafe because these providers have full read/write access to your application's configuration information. A settings provider should be thoroughly vetted before it is adopted for general use.
