Answer 1

There is no CLR type called dynamic. The C# compiler makes all dynamic values of type object and then calls custom binding code to figure out how to handle them. If dynamic was used, it will show up as Object.

But You can check if an instance is of type IDynamicMetaObjectProvider or you can check whether the type implements IDynamicMetaObjectProvider
