Validation: How to inject A Model State wrapper with Ninject?

阅读更多关于 Validation: How to inject A Model State wrapper with Ninject?

I was looking at this tutorial http://asp-umb.neudesic.com/mvc/tutorials/validating-with-a-service-layer--cs on how to wrap my validation data around a wrapper. I would like to use dependency inject though. I am using ninject 2.0 namespace MvcApplication1.Models { public interface IValidationDictionary { void AddError(string key, string errorMessage); bool IsValid { get; } } } // wrapper using System.Web.Mvc; namespace MvcApplication1.Models { public class ModelStateWrapper : IValidationDictionary { private ModelStateDictionary _modelState; public ModelStateWrapper(ModelStateDictionary

问题 I am new to Repository and DI and trying to implement in my MVC 5 project. I implemented Constructor Injection where in my controller has a constructor like this: IBook _ibook; public Test(IBook ibook) { _ibook = ibook; } Without any DI library, it throws an error: There is no empty constructor. To avoid this, I added one more constructor as below: public Test ():this(new Book()) { } Since I am new to DI, I don't want to risk my project by using DI library which can later throw some error

There are plenty of examples for having it worked on an MVC application. How is it done on Web Forms? Here are the steps to use Ninject with WebForms.

Continued Ninject support in ASP.NET MVC 6?

阅读更多关于 Continued Ninject support in ASP.NET MVC 6?

问题 I have been very happily using Ninject for a long time now, and I really like it, but I am faced with a difficult choice since the release of ASP.NET 5 and MVC 6 . Basically, out of the gate, Microsoft has revealed their own dependency injection system; Which is one that to my knowledge has gotten a lot of criticism. But my bigger problem lies with how it affects other libraries. From another question I asked and other resources online, it seems that Ninject does not work out of the box with

Where should I do Injection with Ninject 2+ (and how do I arrange my Modules?)

阅读更多关于 Where should I do Injection with Ninject 2+ (and how do I arrange my Modules?)

I have a solution with two relevant (to this question) projects, and a few others; Class library with functionality used by several other projects. ASP.NET MVC application. My question is basically where I should do IoC with Ninject 2, considering... The class library needs some DI love, among other things in the repository classes which need web request specific session objects (think Unit of Work). The MVC app needs DI since with Ninject 2 you basically inherit from NinjectHttpApplication. Unit tests for the class library need to be aware of this to inject a different set of repositories.

Does Ninject support Func (auto generated factory)?

阅读更多关于 Does Ninject support Func (auto generated factory)?

问题 Autofac automatically generates factories for Func<T> ; I can even pass parameters. public class MyClass { public MyClass(Func<A> a, Func<int, B> b) { var _a = a(); var _b = b(1); } } Can I do the same with Ninject? If not, what workaround can I apply? Thanks. Update : Just found this post, seems the answer is no: How do I handle classes with static methods with Ninject? 回答1: NB Ninject 3.0 and later has this fully supported using the Ninject.Extensions.Factory package, see the wiki:- https:/
