ExpandoObject and DynamicObject classes

Question

Describe ExpandoObject and DynamicObject classes.

Answer 1

The ExpandoObject class is a class whose members can be explicitly added and removed at the runtime. In other words, the ExpandoObject class allows dynamic binding of the objects, that allows you to use standard syntax, same to the dynobj.Method method instead of using more complex syntax, like dynobj.getAttribute("Method").

The DynamicObject class enables you to define the dynamic behavior for an object at the run time. This class cannot be instantiated directly; thus, to implement the dynamic behavior, it is required to  inherit from the DynamicObject class and override the necessary methods. It also allows to define the specific operations that can be performed on dynamic objects as well the methods to perform those operations.
