That syntax appears to have gotten me past that error, thank you!

Since no one else has chimed in, I don't know if type alias supports generics or not, I've never tried it. It might be worth browsing the code to see if it's immediately obvious if there's anything in there for it. _____ From: Tony Selke [mailto:[EMAIL PROTECTED] Sent: Thursday, May 31, 2007 10:08 AM To: [email protected] Subject: <typeAlias> support for C# Generics? I have a problem that I either dont understand or which isnt currently supported by the iBATIS DataMapper (v.1.6.1). Any insight or recommendations are greatly appreciated. I use a heavily customized, generic BindingList as the collection for all of my entity classes. For reference, the type and its super-class are shown below: public class TList<T> : ListBase<T> where T : IEntity, new() public abstract class ListBase<T> : BindingList<T>, IBindingListView, IBindingList, IList, ICloneable, IListSource, ITypedList, IDisposable, IComponent, IRaiseItemChangedEvents, IDeserializationCallback If we use the traditional Northwind-based example, I have the following sqlMap alias section in the config file associated with the Category entity/table: <sqlMap namespace="Northwind.Entities.Categories" . . . > <alias> <typeAlias alias="Instance" type="Northwind.Entities.Categories, Northwind.Entities" /> <typeAlias alias="List" type="Northwind.Entities.TList<Categories>, Northwind.Entities" /> </alias> . . . </sqlMap> When I try to initialize the mapper instance like so: ISqlMapper map = Mapper.Instance(); I get the following inner exception: "Could not load type from string value 'Northwind.Entities.TList<Categories>, Northwind.Entities'.":"" I am guessing that the issue has to do with how the SqlMapper is using reflection to check/instantiate each typeAlias. The reflection code for dealing with generics is a bit more involved than a simple Assembly.LoadFrom() and Assembly.CreateInstance(). More details with an example can be seen here: http://msdn2.microsoft.com/en-us/library/b8ytshk6.aspx While I can probably get around this issue by having collection classes that inherit from a typed-instance of my TList<T>, it sort of defeats much of the purpose of the generic concept. Is there something I am missing? Is there a way to do this without hacking around it?
