Frank,

I posted my IRepository Code on my blog: http://www.techfocus2.com/2008/10/irepository-code/

Also, comments are working now, thanks for pointing that out.

In case you are still not clear. Here is my IRepository definition:

public interface IRepository
{

DTO FindById(int id);

DTO Insert(DTO data);
DTO Update(DTO newData, DTO oldData); // Our Stored Procedure is very old fashion. We don’t have choice.

void Delete(DTO data);

}

public interface IDynamicQueryable
{
IEnumerable FindAllByCriteria(string criteria);
IEnumerable FindAllByCriteria(Func criteria);
}

public interface INameValueListRepository
{
Dictionary GetAll();
}

I always thought DAO and Repository are almost same. Maybe I should look back to the defination more detail. Anyway I think if using LinQ2Sql yield return properly, memeroy won’t be a big issue.

I like this approach, and we are thinking of using a similar technique. For me this is DAO not a repository (although I’m pretty new to this.) From what I have read the Repository pattern lives above the BO.

Regardless of that, have you had any issues with memory, as you will have to copy the contents of DTO into BO. If you have a BusinessListBase with many records then the memory will consume twice the amount?
