ResourceProviderFactory Class
Serves as the base class for classes that create resource providers.
Assembly: System.Web (in System.Web.dll)
| Name | Description | |
|---|---|---|
![]() | ResourceProviderFactory() | When implemented in a derived class, initializes a new instance of the derived class. |
| Name | Description | |
|---|---|---|
![]() | CreateGlobalResourceProvider(String) | When overridden in a derived class, creates a global resource provider. |
![]() | CreateLocalResourceProvider(String) | When overridden in a derived class, creates a local resource provider. |
![]() | Equals(Object) | Determines whether the specified object is equal to the current object.(Inherited from Object.) |
![]() | Finalize() | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.) |
![]() | GetHashCode() | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType() | |
![]() | MemberwiseClone() | |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
ResourceProviderFactory is an abstract class that serves as the base class for objects that return global and local resource providers. Classes must derive from ResourceProviderFactory to implement its functionality.
The following code example shows a customized resource provider factory that retrieves cached values.
