如何在 Redirecttoaction 中传递 List [英] How to pass List in Redirecttoaction

问题描述

我想从 RedirectToAction 方法传递一个以上的参数

I want to pass more then one parameter from RedirectToAction method

我怎样才能通过?

我的一个行动方法

 [HttpPost, ActionName("SelectQuestion")]
    public ActionResult SelectQuestion(string email,List<QuestionClass.Tabelfields> model)
    {

        List<QuestionClass.Tabelfields> fadd = new List<QuestionClass.Tabelfields>();
        for (int i = 0; i < model.Count; i++)
        {
            if (model[i].SelectedCheckbox == true)
            {
                List<QuestionClass.Tabelfields> f = new List<QuestionClass.Tabelfields>();
                fadd.Add(model[i]);
            }
        }

        return RedirectToAction("Question", new { email = email, model = fadd.ToList() });
    }

我的另一个动作方法

    [HttpGet]
    public ActionResult Question(string email,List<QuestionClass.Tabelfields> model)
    {
    }

我没有在模型中获得值.

推荐答案

重定向时不能在 url 中传递复杂对象的集合.

You cannot pass a collection of complex objects in urls when redirecting.

一种可能性是使用 TempData:

One possibility would be to use TempData:

TempData["list"] = fadd.ToList();
return RedirectToAction("Question", new { email = email});

然后在问题操作中:

var model = TempData["list"] as List<QuestionClass.Tablefields>;
