Inheritance Deserialization about serialize.linq HOT 3 CLOSED

can you provide a unit test that fails?

from serialize.linq.

I'll try and whip one together tomorrow, any prefered way of getting it? (Should I just zip it all and upload it somewhere or would you like a 'wall of text' here :-) Assuming I can get it to fail in a small unit test. (It's failing in my system integration tests atm).

I've found the problem, which isn't actually in Serialize.Linq but in an example we use that you posted on your blog in the past, since your blog seems down here is the web archive link;

You mention the following snippet which we used to great success in the past (before we had a class that inherited;

class MyExpressionContext : ExpressionContext
    {
        public override Type ResolveType(TypeNode node)
        {
            var type = base.ResolveType(node);
            if(type == null)
                return null;

            if(type == typeof(PersonDto))
                return typeof(Person);
            return type;
        }
    }

We altered it slightly to be generic and what not but I got things to work when I actually checked on inheritance see the following snippet;

public class DtoExpressionContext<TDto, TActual> : ExpressionContext
    {
        public override Type ResolveType(TypeNode node)
        {
            var type = base.ResolveType(node);
            if (type == null)
                return null;

            Type dtoType = typeof (TDto);

            if (type == dtoType || dtoType.IsSubclassOf(type))
                return typeof(TActual);
            return type;
        }
    }

Since this isn't an issue within Serialize.Linq at all i'll close this, however should you decide to blog again (or maybe this code is in the examples as well, I didn't check that) you could change it slightly to allow for the inheritance.
