How do return Page with a model in ASP.Net Core Razor Page

问题

How to I Redirect to a Page and Passing its model? Just like what we have in MVC return View(model: MyModel);

What i have tried: return RedirectToPage("/Notify", new { Model = notifierVM });

Note: the Page I want to return has no PageModel behind

回答1:

MVC has built in dictionary object TempData. You can serialize your model, put JSON string into TempData and then on the redirected action you can get and deserialize JSON string into object.

public ActionResult Create(Booking item)
{
    TempData["data"] = JsonConvert.SerializeObject(MyModel);
    return RedirectToAction("Details", new { id = 1 });
}

On other action

public ActionResult Details(int id)
{
    object o;
    TempData.TryGetValue("data", out o);
    var MyModel = JsonConvert.DeserializeObject<T>((string)o);
    ...
    ...
}
