Public Overridable Function GetTypeDescriptor (objectType As Type, instance As Object) As ICustomTypeDescriptor

Parameters

objectType
Type

The type of object for which to retrieve the type descriptor.

instance
Object

An instance of the type. Can be null if no instance was passed to the TypeDescriptor.

Returns

An ICustomTypeDescriptor that can provide metadata for the type.

Remarks

This method is prototyped as virtual and, by default, returns an empty descriptor if no parent provider was passed. If a parent provider was passed, this method will invoke the parent provider's GetTypeDescriptor method.

Notes to Inheritors

The GetTypeDescriptor(Type, Object) method should return a custom type descriptor for the object. If the method does not provide type information for the object, it should return null.
