我将这一行动过滤器安装在所有行动方法实施之前。
protected override void OnActionExecuting(ActionExecutingContext filterContext)
{
//code omitted
UpdateModel(MyModel);
}
在行动A、B、C本应执行,而不是D时,我希望这一行动能够更新这一模式。 我如何防止这种过滤行动在D执行时更新模型? 因此,可以知道如何使用上面的<>行动......ExecutingContentfilContext?

你这样做的方法是,将行动A、B和C与属性联系起来,而不是D。
你们得到了答案,但是,你打算这样做,这确实是坏事。 如果有人在另一个控制器上写了一种行动方法,如果这一特性should,那么,那么,通过机会选择了你过滤的名字。 独角兽部队赢得了 t,这是一场明显的丑恶,但是,正如人们所告诉的那样。 这将是一条 maintain夜。
无,这样做的清洁办法是,将属性从控制层移至所有控制器的操作方法级,而如果存在某种行动方法,则这种归属应如此。 这使得人们很容易看到,仅仅看看看控制器法,当其特性会发生时,如果它不发生,它就会像预期的那样发挥作用。
