如何使用新的Subsonic 3.0 IRepository模式

Question

Can someone (hopefully Rob) explain how to implement the new SubSonicRepository<> Pattern? I have used it with the old version and the MVC templates (in web forms) using the following initialization.

    public IRepository<StaffingPosition> _StaffingPositionsRepository;

    public  StaffingBase()
    {
        _StaffingPositionsRepository = new SubSonicRepository<StaffingPosition>();
    }
    public StaffingBase(IRepository<StaffingPosition> staffingpositionsRepo)
    {
        _StaffingPositionsRepository = staffingpositionsRepo;
    }

Note that my WCF Service inherits this class for ease of access.
Now SubSonicRepository() requires an argument of IQuerySurface and I'm not sure the best way to make this happen. I really dig the IRepository pattern and want to try to stick with it if possible...That is, unless anyone has better ideas. Thanks!

Answer 1

The templates generate a new class that implement IQuerySurface, the name of which you can configure in the main .tt file (usually something like NorthwindDb). Usually all that is needed is to pass a new instance of this class to the repository:

_StaffingPositionsRepository = new SubSonicRepository<StaffingPosition>(new StaffingDB());
