在 Dotnet Core 3.1 中将数据从一个 controller 传递到另一个

Question

I am a newbie to the whole MVC pattern, stuck with the following issue:

I have 2 controllers, PayReqController and PayResController . I am trying to access data from one action of PayReqController to another action of PayResController . I have tried using TempData :

TempData["tsnpac"] = tsnpac; 

But it doesn't work because we need to redirect to another controller after setting the TempData . Also tried using session Session["TSNPAC"] = "TSNPAC"; to access it to another controller, but it is giving the value as null .

My scenario is that in PayReqController , inside an action I have a value which I need to get that in another controller without redirecting to that controller, because my use case is to redirect to some other URL which I get as a response from other service.

I tried TempData but different than this approach and it worked.

I serialized my list when storing it in TempData

AccountController:

TempData["BiUsers"] = JsonConvert.SerializeObject(users);

(users is an IEnumerable of UserModel)

And deserialized it in another controller in which I wanted to use that IEnumerable.

HomeController:

var users = JsonConvert.DeserializeObject<IEnumerable<UserModel>>(TempData["BiUsers"].ToString());
