Bind EditorFor to Array of string

Question

After trying with a more sophisticated viewmodel with no success I came to use a viewmodel which is like this:

public class CarteExpressViewModel
{
    public string[] LesEntrees;      
    public string[] LesPlats; 

    public CarteExpressViewModel()
    {
        LesEntrees = new string[]{ "", "", "", "", "", "" };
        LesPlats = new string[]{ "", "", "", "", "", "" };
    }
}

I pass the viewModel in my create method of my controller

public ActionResult Create()
{
    CarteExpressViewModel carteExpressViewModel = new CarteExpressViewModel();
    return View(carteExpressViewModel);
}

Problem is I can see the input value if I use a FormCollection as parameter of my Post create method but everything is null if i use the viewmodel My view is line this:

@for (int i = 0; i < Model.LesEntrees.Length; i++)
{

    <div class="editor-label ">
        @Html.LabelFor(model => model.LesEntrees[i], "Entrée n°" + (i + 1).ToString(), new { @class = " express_input_label" })
    </div>
    <div class="editor-field  ">
        @Html.EditorFor(model => model.LesEntrees[i], new { @class = " express-input" })
    </div>
}

I can't see what's wrong but sure something should.

You set up the variables as fields, not properties. Change them to:

public string[] LesEntrees { get; set; }
public string[] LesPlats { get; set; }

Further to Chris Pratt answer, yes I should use properties but it's not enough since there is a problem with array (see http://forums.asp.net/t/1597890.aspx?Collection+is+read+only+Arrays+in+models) So I came back to my less simple viewmodel which use Lists and this one works.....
