I'm working a simple EF/MVC app and I'm trying to implement some Repositories to handle my entities. I've set up a BaseObject Class and a IBaseRepository Interface to handle the most basic operations so I don't have to repeat myself each time:
public abstract class BaseObject<T>
{
public XA.Model.Entities.XAEntities db;
public BaseObject()
{
db = new Entities.XAEntities();
}
public BaseObject(Entities.XAEntities cont)
{
db = cont;
}
public void Delete(T entity)
{
db.DeleteObject(entity);
db.SaveChanges();
}
public void Update(T entity)
{
db.AcceptAllChanges();
db.SaveChanges();
}
}
public interface IBaseRepository<T>
{
void Add(T entity);
T GetById(int id);
IQueryable<T> GetAll();
}
But then I find myself having to implement 3 basic methods in every Repository ( Add, GetById & GetAll):
public class AgencyRepository : Framework.BaseObject<Agency>, Framework.IBaseRepository<Agency>
{
public void Add(Agency entity)
{
db.Companies.AddObject(entity);
db.SaveChanges();
}
public Agency GetById(int id)
{
return db.Companies.OfType<Agency>().FirstOrDefault(x => x.Id == id);
}
public IQueryable<Agency> GetAll()
{
var agn = from a in db.Companies.OfType<Agency>()
select a;
return agn;
}
}
How can I get these into my BaseObject Class so I won't run in conflict with DRY.
