我可以使用IoC容器来创建ASP.NET webforms页面和控件吗？

Question

With ASP.NET MVC it is pretty easy to integrate an IoC container to create the controllers.

Is the same thing also possible with webforms to create the pages and controls and pass them any dependencies? If yes, where do I have to plug it in?

Answer 1

是的，你可以，这里是Spring.NET如何做到这一点的一个例子。

Answer 2

Castle Windsor was the first major IoC container for ASP.NET. See this question discussing how it can be used with Web forms.

Answer 3

Not directly, as Web Forms does not allow any code to take control of Page and Control instantiation. So something like a Page Factory is not feasible, and you can't do constructor injection.

But there are work arounds/hacks that can buy you setter injection as others have mentioned.

Answer 4

另一个好方法是使用Model-View-Presenter模式，并将您的依赖项注入到演示者的构造函数中。

Answer 5

I know this question is very old but in the .NET Framework 4.7.2+ you can have constructor injection in ASP.NET WebForm pages and user controls.

From this official blog post :

Areas that Dependency Injection can be used

There are many areas you can use Dependency Injection in WebForms applications now. Here is a complete list.

• Pages and controls WebForms page User control Custom control
• IHttpHandler and IHttpHandlerFactory
• IHttpModule Providers
• BuildProvider
• ResourceProviderFactory
• Health monitoring provider
• Any ProviderBase based provider created by System.Web.Configuration.ProvidersHelper.InstantiateProvider . eg custom session state provider
