使用 RedirectToAction 传递模型和参数 [英] passing model and parameter with RedirectToAction

问题描述

我想向另一个动作发送一个字符串和一个模型(对象).

I want to send a string and a model (object) to another action.

var hSM = new HotelSearchModel();
hSM.CityID = CityID;
hSM.StartAt = StartAt;
hSM.EndAt = EndAt;
hSM.AdultCount = AdultCount;
hSM.ChildCount = ChildCount;

return RedirectToAction("Search", new { culture = culture, hotelSearchModel = hSM });

当我使用 new 关键字时，它会发送 null 对象，尽管我设置了对象的 hSm 属性.

When I use the new keyword it sends null object, although I set the objects hSm property.

这是我的搜索操作:

public ActionResult Search(string culture, HotelSearchModel hotelSearchModel)
{ 
    // ...
}

推荐答案

您不能使用 RedirectAction 发送数据.那是因为您正在执行 301 重定向，然后返回到客户端.

You can't send data with a RedirectAction. That's because you're doing a 301 redirection and that goes back to the client.

您需要将其保存在 TempData 中:

What you need to is save it in TempData:

var hSM = new HotelSearchModel();
hSM.CityID = CityID;
hSM.StartAt = StartAt;
hSM.EndAt = EndAt;
hSM.AdultCount = AdultCount;
hSM.ChildCount=ChildCount;
TempData["myObj"] = new { culture = culture,hotelSearchModel = hSM };

return RedirectToAction("Search");

之后，您可以再次从 TempData 中检索:

After that you can retrieve again from the TempData:

public ActionResult Search(string culture, HotelSearchModel hotelSearchModel)
{
    var obj = TempData["myObj"];
    hotelSearchModel = obj.hotelSearchModel;
    culture = obj.culture;
}
