SettingsProviderAttribute Class

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

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

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

Caution noteCaution:

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.
