Scenario:
public interface IEntity {
int Id {get; set;};
}
public interface IRepository<T> where T: class, IEntity {
//repo crud stuffs here
}
public class RepositoryBase<T> : IRepository<T> where T : class, IEntity {
//general EF crud implementation
}
public class MyEntity : IEntity {
//implementation and other properties
}
public interface IMyEntityRepository : IRepository<MyEntity> {
//any extending stuff here
}
public class MyEntityRepository : RepositoryBase<MyEntity>, IMyEntityRepository {
//implementation here
}
public interface IBusinessLogic<T> where T : class, IEntity {
}
public class BusinessLogicBase<T> : IBusinessLogic<T> where T : class, IEntity {
private readonly IRepository<T> _baseRepo;
private readonly IList<IRepository<IEntity> _repositories;
public BusinessLogicBase(IRepository<T> baseRepo, params IRepository<IEntity>[] repositories) {
_baseRepo = baseRepo;
_repositories = repositories;
}
//some standard business logic methods that resolve the repositories based on navigation property types and call
private IRepository<U> ResolveRepository<U>() where U: class, IEntity {
IRepository<U> found = null;
foreach (IRepository<IEntity> repository in _repositories) {
if (repository.IsFor(typeof(U))) {
found = repository as IRepository<U>;
break;
}
}
return found;
}
}
public interface IMyEntityBL : IBusinessLogic<MyEntity> {
//extended stuff here
}
public class SomeOtherEntity : IEntity {
}
public interface ISomeOtherEntityRepository : IRepository<SomeOtherEntity> {
}
public interface SomeOtherEntityRepository : RepositoryBase<SomeOtherEntity>, ISomeOtherEntityRepository {
}
public class MyEntityBL : BusinessLogicBase<MyEntity>, IMyEntityBL {
public MyEntityBL(IRepository<MyEntity> baseRepo, ISomeOtherEntityRepository someOtherEntityRepo) : base(baseRepo, someOtherEntityRepo) {
//ERROR IS HERE WHEN TRYING TO PASS ISomeOtherEntityRepository to base
}
//implementation etc here
}
Why can I not pass ISomeOtherEntityRepository to base? I get the "is not assignable parameter type" error. It implements IRepository and SomeOtherEntity is an IEntity so I don't see why what I'm attempting is invalid. Can someone please advise?
