TypeDescriptionProvider Class
Assembly: System (in system.dll)
The TypeDescriptionProvider class dynamically extends the type information associated with a type or object by adding, modifying, or hiding characteristics such as attributes, properties, and events. There can be multiple type description provider classes that offer metadata to a single TypeDescriptor.
There are two ways to associate a TypeDescriptionProvider with a TypeDescriptor:
-
At design time, when the target class can be assigned the appropriate TypeDescriptionProviderAttribute tag.
-
At run time, when one of the AddProvider methods of the TypeDescriptor class can be called. These overloaded methods require either the target object or its class type.
The TypeDescriptionProvider class relies on a parent object of the same type, supplied during construction. This allows classes that derive from CustomTypeDescriptor to selectively override methods.
Instances of TypeDescriptionProvider are only built upon demand, minimizing the impact of custom type information on performance.
This class cannot be inherited.
