How do I reflect over the members of dynamic object?

Question

I need to get a dictionary of properties and their values from an object declared with the dynamic keyword in .NET 4? It seems using reflection for this will not work.

Answer 1

In the case of ExpandoObject, the ExpandoObject class actually implements IDictionary for its properties, so the solution is as trivial as casting:

IDictionary propertyValues = (IDictionary)s;

Note that this will not work for general dynamic objects. In these cases you will need to drop down to the DLR via IDynamicMetaObjectProvider.
