Gets a custom type descriptor for the given type and object.
public:
virtual System::ComponentModel::ICustomTypeDescriptor ^ GetTypeDescriptor(Type ^ objectType, System::Object ^ instance);public virtual System.ComponentModel.ICustomTypeDescriptor? GetTypeDescriptor(Type objectType, object? instance);public virtual System.ComponentModel.ICustomTypeDescriptor GetTypeDescriptor(Type objectType, object instance);abstract member GetTypeDescriptor : Type * obj -> System.ComponentModel.ICustomTypeDescriptor
override this.GetTypeDescriptor : Type * obj -> System.ComponentModel.ICustomTypeDescriptorPublic Overridable Function GetTypeDescriptor (objectType As Type, instance As Object) As ICustomTypeDescriptorParameters
- 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.
