在asp.net web窗體中實現autofac

我正在開發ASP.net Web窗體，並且我想要在網站中實現AutoFac。在asp.net web窗體中實現autofac

我遵循了以下鏈接步驟： https://code.google.com/p/autofac/wiki/WebFormsIntegration

但我得到這個錯誤：

This module requires that the HttpApplication (Global Application Class) implements IContainerProviderAccessor.

我無法找到我的項目Global.asax.cs，只有Global.asax。

Global.asax：

<%@ Application Language="C#" %> 
<%@ Import Namespace="Autofac" %> 
<%@ Import Namespace="Autofac.Integration.Web" %> 
<script RunAt="server"> 
    public class Global : HttpApplication, IContainerProviderAccessor { 

     // Provider that holds the application container. 
     static IContainerProvider _containerProvider; 

     // Instance property that will be used by Autofac HttpModules 
     // to resolve and inject dependencies. 
     public IContainerProvider ContainerProvider { 
      get { return _containerProvider; } 
     } 

     void Application_Start(object sender, EventArgs e) { 
      // Code that runs on application startup 

      // Build up your application container and register your dependencies. 
      var builder = new ContainerBuilder(); 
      //builder.RegisterType<SomeDependency>(); 
      // ... continue registering dependencies... 

      // Once you're done registering things, set the container 
      // provider up with your registrations. 
      _containerProvider = new ContainerProvider(builder.Build()); 
     } 
    } 
</script>

任何想法？非常感謝你！

這些部分必須在web.config文件中定義，以便注入工作。請參閱https://code.google.com/p/autofac/wiki/WebFormsIntegration#Implement_IContainerProviderAccessor_in_Global.asax

我已經在web.config中添加了，仍然有相同的錯誤... –

我也有這個問題，並通過創建一個global.asax.cs文件並從原始的global.asax文件引用它來修復它。這使您能夠實現所需的IContainerProviderAccessor界面。

文件：Global.asax中

<%@ Application Codebehind="Global.asax.cs" Inherits="MyCompany.WebForms.Global" Language="C#" %>

文件：Global.asax.cs中

using Autofac; 
using Autofac.Core; 
using Autofac.Integration.Web; 
using .... 


namespace MyCompany.WebForms 
{ 
    public partial class Global : HttpApplication, IContainerProviderAccessor 
    { 
     // Provider that holds the application container. 
     static IContainerProvider _containerProvider; 

     // Instance property that will be used by Autofac HttpModules 
     // to resolve and inject dependencies. 
     public IContainerProvider ContainerProvider 
     { 
      get { return _containerProvider; } 
     } 

     protected void Application_Start(object sender, EventArgs e) 
     { 
      .... 
     } 
    } 
}

實施在此之後，我還與問題未能加載類型「MyCompany.WebForms.Global '錯誤，直到我移動Global.asax.cs文件到App_Code文件夾和更新CodeBehind參考Global.asax。
