The 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 with a TypeDescriptor:
At design time, when the target class can be assigned the appropriate TypeDescriptionProviderAttribute tag.
The 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 are only built upon demand, minimizing the impact of custom type information on performance.
This class cannot be inherited.Notes to Inheritors:
Your derived type might be marked as internal or private, but an instance of your type can be created with the TypeDescriptor class. Do not write insecure code by assuming the caller is trusted. Assume instead that callers might create instances of your type in partial trust.
