ASP.NET MVC 将对象从自定义操作过滤器传递到操作 [英] ASP.NET MVC Pass object from Custom Action Filter to Action

问题描述

如果我在 ASP.NET MVC 的自定义操作过滤器中创建一个对象

If I create an object in a Custom Action Filter in ASP.NET MVC in

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

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

}

有什么方法可以从当前正在执行的 Action 中访问该对象.

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

推荐答案

我建议把它放在 Route 数据中.

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();
    }
