asp.net – 使用ninject时出现异常

2023年11月10日 247次阅读

我一直在尝试使用Asp.Net Pro MVC 2中的示例,第3章作者使用ninjet进行依赖注入,我已经将代码转换为vb.net,因为他使用了c#,添加了引用但是当我尝试运行代码我得到一个例外

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

System.InvalidProgramException异常,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

这是例外细节：

最佳答案 没有理由说VB应该表现得很差.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 })
