Interface inheritance with IDisposable?
c#, inheritance
Solution
My guess is that you are making a mistake- either you have not recompiled the assembly containing the `IRepository<T>` interface since you made it inherit from `IDisposable`, or you are referencing the wrong copy of it, or you are referencing some other `IAddressRepository`.
Try doing a Clean, then a Rebuild All, and check the paths on your references. If the projects are in the same solution, make sure you are referencing the project containing `IRepository<T>` / `IAddressRepository` and not the DLL.
Also make sure that `AddressRepository` actually implements `IAddressRepository`. It might just be reporting the wrong error.
EDIT: So the resolution seems to be that the assembly containing `AddressRepository`'s parent class was not compiling. This caused the debugger to complain about `AddressRepository` not implementing `IDisposable`, rather than the (more sensible) " inaccessible due to its protection level" error compiling the class itself. My guess is you had that error too, but were addressing this one first.
Problem
I have the following inheritance hierarchy: ``` public interface IRepository<T> : IDisposable { void Add(T model); void Update(T model); int GetCount(); T GetById(int id); ICollection<T> GetAll(); } public interface IAddressRepository : IRepository<Address> { } ``` And this code: ``` var adrs = new Address[]{ new Address{Name="Office"} }; using (IAddressRepository adrr = new AddressRepository()) foreach (var a in adrs) adrr.Add(a); ``` However, this code does not compile. It gives me this error message: ``` Error 43 'Interfaces.IAddressRepository': type used in a using statement must be implicitly convertible to 'System.IDisposable' ``` However, a parent of `IAddressRepository` inherits from `IDisposable`. What is happening here? How do I make the code compile?
