如何在 controller 中使用来自 razor 视图的变量

Question

I have variable in my layout.cshtml and I would like to use it in my controller. Is this possible and how to accomplish this?

Answer 1

Although Model Binding is one way in Razor Views but using the hack on TempData , you accomplish this.

public ActionResult Foo()
{
    SomeModel model = ...
    TempData["foo"] = model;
    return RedirectToAction("Bar");
}

public ActionResult Bar()
{
    var model = TempData["foo"] as SomeModel;
    ...
}
