MVC5，WebAPI2和Ninject参数的构造函数错误 [英] MVC5, WebAPI2 and Ninject Parameterless constructor error

问题描述

所以，我有完全相反的问题，因为 MVC5，网页API 2和Ninject

So I have the exact opposite problem as MVC5, Web API 2 and and Ninject

我有一个新的MVC5 / WebAPI2工程，即同时具有控制器S和ApiControllers。

I have a new MVC5/WebAPI2 project, that has both "Controller"s and "ApiControllers".

我使用Ninject.Web.WebAPI的最新版本不稳定，没有code更改NinjectDependencyResolve.cs和Ninject.WebCommom.cs（除了绑定我的依赖）的ApiController的构造函数注入的作品。然而，当我叫MVC控制器我得到：

I'm using the latest unstable version of Ninject.Web.WebAPI with no code changes to NinjectDependencyResolve.cs and Ninject.WebCommom.cs (besides binding my dependency) the ApiController's constructor injection works. However, when I call a MVC Controller I get:

此对象定义无参数的构造函数。

No parameterless constructor defined for this object.

推荐答案

的问题是你需要依赖解析器为MVC和的WebAPI。根据所设定的Ninject库使用，你只能得到那些你在有线之一。

The issue is you need a Dependency Resolver for both MVC and WebAPI. Depending on which set of Ninject libraries you use, you only get one of those wired in for you.

即。如果使用Ninject.Web.WebAPI库，您将需要手动设置MVC解析器：

i.e. if you use the Ninject.Web.WebAPI library you will need to manually set the MVC resolver:

System.Web.Mvc.DependencyResolver.SetResolver(new NinjectResolver(kernel)); 

（我在NinjectWebCommon.cs这样做 CreateKernel（））

您Ninject解析器可以继承为的WebAPI和MVC接口：

Your Ninject resolver can inherit the interface for both WebAPI and MVC:

public class NinjectResolver : NinjectScope, 
    System.Web.Http.Dependencies.IDependencyResolver, 
    System.Web.Mvc.IDependencyResolver
