问题
I'm trying to Bind a generic IRepository<> interface to my generic Repository<> - however it always return null?
I have tried various things like:
Bind(typeof(IRepository<CustomerModel>)).To(typeof(Repository<CustomerModel>));
Bind(typeof(IRepository<>)).To(typeof(Repository<>));
However if I pass in a non-generic interface and class then it works like a dream?
回答1:
Bind(typeof(IRepository<>)).To(typeof(Repository<>));
This is the correct syntax for binding an open generic.
If you are receiving null back when requesting IRepository< of whatever >, then there may be some other problem in an area of code you haven't shared.
回答2:
See my answer on MVC3 Controller constructor + Ninject.
Generic Binding works correctly in Ninject. Try using a parameterless constructor in Repository. I think the problem is there.
