ASP.NET MVC 动作过滤器

有谁知道即使在 CATCH 块中，ActionFilterAttribute 类的 OnResultExecuted 方法是否也会执行？

ie:

        [CookiesActions]
        public ActionResult Login(Usuarios usuario)
[...]
            return View(new UsersViewModel(sceUsuarios.Usuario,true));
            }
            catch
            {
                return View(new UsersViewModel(new Usuarios(),true));//is OnResultExecuted fired here?
            }
[...]

简而言之：YES.

您可以使用简单的日志操作过滤器来验证这一点。

public class LogAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        Log("OnActionExecuting", filterContext.RouteData);
    }

    public override void OnActionExecuted(ActionExecutedContext filterContext)
    {
        Log("OnActionExecuted", filterContext.RouteData);
    }

    public override void OnResultExecuting(ResultExecutingContext filterContext)
    {
        Log("OnResultExecuting", filterContext.RouteData);
    }

    public override void OnResultExecuted(ResultExecutedContext filterContext)
    {
        Log("OnResultExecuted", filterContext.RouteData);
    }


    private void Log(string methodName, RouteData routeData)
    {
        var controllerName = routeData.Values["controller"];
        var actionName = routeData.Values["action"];
        var message = String.Format("{0} controller:{1} action:{2}", methodName, controllerName, actionName);
        Debug.WriteLine(message, "Action Filter Log");
    }

}

如果将 [Log] 属性放在方法上，即使您吞下了异常，您也会看到 OnResultExecuted 被写入以进行调试。
