Get the "key" for a strongly typed model in the controller

So, I'm trying to get the key for the model object in the controller to add AddModelErrorto it.

In my opinion, I use

@Html.ValidationMessageFor(model => model.Email)

What is the equivalent code to get a name Keyto add to the controller so that it connects to this ValidationMessage.
