我使用Microsoft的Unity进行依赖注入,我想做这样的事情:

IDataContext context = _unityContainer.Resolve<IDataContext>();
var repositoryA = _unityContainer.Resolve<IRepositoryA>(context); //Same instance of context
var repositoryB = _unityContainer.Resolve<IRepositoryB>(context); //Same instance of context

IDataContext context2 = _unityContainer.Resolve<IDataContext>(); //New instance
var repositoryA2 = _unityContainer.Resolve<IRepositoryA>(context2);

RepositoryA并且RepositoryB都有一个带IDataContext参数的构造函数,我希望Unity使用我传递它的上下文初始化存储库.另请注意,IDataContext未在Unity中注册(我不想要3个实例IDataContext).
