MVC2 FormCollection options

Question

I'm just getting started with MVC2 and going through the NerdDinner examples. I noticed that there seems to be multiple ways to pass in the form values for example:

FormColelction formvalues
FormCollection collection
FormCollection form

Why would you use one over the other and why? Does it also relate to whether you are using Entity Framework?

Answer 1

Each of the above examples is passing in the same type (FormCollection) but with just a different variable name.

It would have been nice to see some consistency in NerdDinner.

You can also have MVC automagically populate a custom object from your form instead of using the generic FormCollection.

EG If your form being posted has fields for FirstName, LastName and Age (representing a person) you could have a method like

[HttpPost]
public ActionResult Create(Person person)
{
    //person is already populated    
}

Answer 2

[HttpPost]
public ActionResult Create([Bind(Exclude = "id")]Person post_person)
{
      // post_person => auto populate formpost values 
      // [Bind(Exclude = "id")] => excluding auto populate identity field 
}
