TypeDescriptionProvider Class

Definition

Provides supplemental metadata to the TypeDescriptor.

public abstract class TypeDescriptionProvider

Remarks

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:

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.

Constructors

TypeDescriptionProvider()

Initializes a new instance of the TypeDescriptionProvider class.

TypeDescriptionProvider(TypeDescriptionProvider)

Initializes a new instance of the TypeDescriptionProvider class using a parent type description provider.
