如何使用Autofac将依赖项注入MVC 5全局过滤器

using System.Web.Mvc;

public class CustomFilter : IActionFilter
{
    private readonly IDependency _dependency;

    public CustomFilter(IDependency dependency)
    {
        _dependency = dependency;
    }

    public void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // 过滤器执行前的逻辑
    }

    public void OnActionExecuted(ActionExecutedContext filterContext)
    {
        // 过滤器执行后的逻辑
    }
}

using Autofac;
using Autofac.Integration.Mvc;
using System.Web.Mvc;

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {
        // 注册依赖关系
        var builder = new ContainerBuilder();
        
        // 注册控制器
        builder.RegisterControllers(typeof(MvcApplication).Assembly);
        
        // 注册依赖项
        builder.RegisterType<Dependency>().As<IDependency>();

        // 注册过滤器
        builder.RegisterFilterProvider();
        builder.RegisterType<CustomFilter>().As<IActionFilter>();

        // 构建容器
        var container = builder.Build();

        // 设置依赖解析器
        DependencyResolver.SetResolver(new AutofacDependencyResolver(container));

        // 其他应用程序初始化逻辑
        // ...
    }
}

[CustomFilter]
public class HomeController : Controller
{
    // 控制器逻辑
    // ...
}
