如何在ASP.NET MVC 4中使用Ninject从Web.config绑定设置？

Question

I have a Repository that accepts a Provider which requires a ProviderCredentials object be passed into it. The ProviderCredentials object is a class, but it's values are only known at run time because they live in the Web.config in the <applicationSettings /> section.

How can I take the values out of the Web.config, build the ProviderCredentials object and inject it into the Provider using Ninject? Not sure if it matters, but the Provider and ProviderCredentials classes live in a separate project than the MVC project in the same solution.

You may consider binding ProviderCredentials by way of a factory method, forcing the kernel to resolve its reference using your own custom logic:

kernel.Bind<ProviderCredentials>()
      .ToMethod(context =>
             new ProviderCredentials(ConfigurationManager.AppSettings["Foo"])
      );
