c#之在 asp.net web 窗体中实现 autofac

我正在开发 ASP.net Web 窗体，我想在网站中实现 AutoFac。

我已按照以下链接中的步骤操作: https://autofaccn.readthedocs.io/en/latest/integration/webforms.html

但是我得到了这个错误:

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

我在我的项目中找不到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> 

有什么想法吗？非常感谢!

请您参考如下方法:

我也有这个问题，并通过创建一个 global.asax.cs 文件并从原始 global.asax 文件中引用它来修复它。这使您能够实现所需的 IContainerProviderAccessor 接口(interface)。

文件:Global.asax

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

文件:Global.asax.cs

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) 
        { 
             .... 
        } 
    } 
} 

在实现这个之后，我也遇到了 Could not load type 'MyCompany.WebForms.Global' 错误的问题，直到我将 Global.asax.cs 文件移动到 < strong>App_Code 文件夹并更新了 CodeBehind 引用 Global.asax。
