Question

我一直在尝试使用Asp.Net Pro MVC 2中的示例，其中作者使用ninjet进行依赖注入，我将代码转换为vb.net，因为他使用了c＃，添加了引用，但是当时我试图运行代码我在

上得到一个例外

Return DirectCast(kernel.Get(controllerType), IController)

异常是System.InvalidProgramException，但是当我使用c＃的作者代码时，它工作正常并成功传递该行，

所以任何人都可以帮助我

这是例外情况：

VB没有理由表现出不同的行为。您确定使用相同的代码吗？或者尝试使用基于反射的注射：

new StandardKernel(new NinjectSettings { UseReflectionBasedInjection = true })

使用ninject时出现异常
