Dynamically adding members to a dynamic object

Question

I\'m looking for a way to add members dynamically to an dynamic object. OK, I guess a little clarification is needed...

When you do that :

dynamic fo         


        

Answer 1

ExpandoObject implements IDictionary albeit explicitly. What this means is that you can simply cast the ExpandoObject to IDictionary and manipulate the dictionary.

dynamic foo = new ExpandoObject();
foo.Bar = 42;
food = (IDictionary)foo;
food["Baz"] = 54
