问题 It looks like an IValueFormatter takes a value of type object and returns a value of type string , while a ValueResolver<TSource, TDestination> takes a value of any type and returns a value of any type. So, it's more flexible. There is also the matter that, with a ValueResolver , you never need to cast the source to a particular type--you define it explicitly in your class definition. Given this, why use IValueFormatter ? Does it do anything that can't be done with ValueResolver ? Am I
