How to do Linq on ITypedList?

Question

So far, I find Linq can be used on existing fields and properties of a class, not on virtual properties. In other words, ITypedList can not work with Linq, even by dynamic Linq.

I tried the following code:

    IQueryable contact ; ...

    dynamic l = contact.Select("Customer.Name as Name"); 
   // Customer is a virtual property provided by the interface of ITypedList.

Then, I met the exception of "No linkedPropertyName or field 'Customer' exists in type 'Contact'".

I traced into dynamic Linq and found the following code raised the exception:

            MemberInfo member = FindPropertyOrField(type, id, instance == null);
            if (member == null)
                throw ParseError(errorPos, Res.UnknownPropertyOrField,
                    id, GetTypeName(type));
            return member is PropertyInfo ?
                Expression.Property(instance, (PropertyInfo)member) :
                Expression.Field(instance, (FieldInfo)member);

in the method of Expression ParseMemberAccess(Type type, Expression instance).

It is obvious only real member of fields and properties are supported in Linq.

But I still expect someone may have found a way to do Linq on virtual properties.

If you find a way to do so, please share your experience.

Thank you in advance,
