从自定义操作筛选器操作ASP.NET MVC通行证对象 [英] ASP.NET MVC Pass object from Custom Action Filter to Action

问题描述

如果我在

public override void OnActionExecuting(ActionExecutingContext filterContext)
{
    DetachedCriteria criteria = DetachedCriteria.For<Person>();
    criteria.Add("stuff");

    // Now I need to access 'criteria' from the Action.....

}

有什么办法，我可以从当前正在执行的行动访问对象。

is there any way I can access the object from the Action that is currently executing.

推荐答案

我会建议把它在路径数据。

I would recommend putting it in the Route data.

    protected override void OnActionExecuting(ActionExecutingContext filterContext)
    {
        filterContext.RouteData.Values.Add("test", "TESTING");
        base.OnActionExecuting(filterContext);
    }

    public ActionResult Index()
    {
        ViewData["Message"] = RouteData.Values["test"];

        return View();
    }
