将上下文数据传递到依赖关系树

Question

我使用ninject进行构造函数注入，我的代码类似于：

public class MyRootClass
{
    public MyRootClass(
        [SetContext("catSession")] IRepository<Cat, int> catRep,
        [SetContext("dogSession")] IRepository<Dog, int> dogRep))
    {
        //set some stuff here
    }                 
}

public class GenericRepository<TEntity, TID> : IRepository<TEntity, TID>
{
    public GenericRepository(IUnitOfWork unitOfWork)
    {
        //set some stuff here
    }
}

public class MyUnitOfWork : IUnitOfWork
{
    //sessionFactory should be bound to the either a cat session, or dog
    //session depending on what the caller (MyRootClass) has currently
    //set in the context
    public MyUnitOfWork([ReadContext] ISessionFactory sessionFactory)
    {
        //set some stuff here
    }
}

ISessionFactory将绑定NinjectModule中绑定的每个会话（cat和dog）。它们是命名绑定。我本质上希望能够要求将IRepository<TEntity, TID>注入到调用类中，并让调用类指定存储库应该在幕后使用的会话。

如何在MyRootClass中设置一些上下文变量，用于确定哪个会话Ninject应该在依赖树的某处注入？
