ASP.NET MVC - 以编程方式添加动作过滤器

public class SampleActionFilter : IActionFilter
{
    public void OnActionExecuting(ActionExecutingContext filterContext)
    {
        // 在控制器操作执行前执行的逻辑
    }

    public void OnActionExecuted(ActionExecutedContext filterContext)
    {
        // 在控制器操作执行后执行的逻辑
    }
}

public class FilterConfig
{
    public static void RegisterGlobalFilters(GlobalFilterCollection filters)
    {
        filters.Add(new SampleActionFilter());
    }
}

[SampleActionFilter]
public class HomeController : Controller
{
    // ...
}

public class HomeController : Controller
{
    [SampleActionFilter]
    public ActionResult Index()
    {
        // ...
    }
}
