What are the differences between System.Dynamic.ExpandoObject , System.Dynamic.DynamicObject and dynamic ? In which situations do you use these types? SLaks The dynamic keyword is used to declare variables that should be late-bound. If you want to use late binding, for any real or imagined type, you use the dynamic keyword and the compiler does the rest. When you use the dynamic keyword to interact with a normal instance, the DLR performs late-bound calls to the instance's normal methods. The IDynamicMetaObjectProvider interface allows a class to take control of its late-bound behavior. When

问题 I'm still experimenting with DynamicObjects. Now I need some information: I'm trying to bind an object inheriting from DynamicObject to a WPF DataGrid (not Silverlight). How do I get the DataGrid to automatically create its columns from the available public properties of the object that are typically generated at runtime? Is that possible actually? 回答1: There is no uniform way to query dynamic properties, generally it's expected that you know them ahead of time. With DynamicObject ,
