c# - ASP.NET MVC CheckBoxList from model with List Property

Question

Apologies if the title is unclear.

I'm trying to return my model from a form submit in ASP.NET MVC.

My question is nearly the same as this question, only differing in that I don't have a List<Model> but a model like:

public Model
{
     string UserName {get; set;}
     string Password {get; set;}
     List<Roles> UserRoles {get; set;}
}

where I need the UserRoles as checkboxes that the admin can select from when creating a new user. My question is, I'm unsure how to use a '@Html.CheckBoxFor' against a list. I tried this:

 @for (var i = 0; i < Model.UserRoles.Count();i++ )
 {
   @Html.HiddenFor(model => model.UserRoles[i].RoleID)
   @Html.CheckBoxFor(model => model.UserRoles[i].Selected)
   @Html.LabelFor(model => model.UserRoles[i].Name)
 }

which in no way worked - every label on the page is "Name", and my List was empty in the POST. Can anyone offer me any guidance on this?

No need to go away from Razor at all.

This works for me:

for (var i = 0; i < Model.UserRoles.Count(); i++)
{
    var role = Model.UserRoles[i];
    @Html.HiddenFor(model => model.UserRoles[i].RoleId)
    @Html.CheckBoxFor(model => model.UserRoles[i].Selected)
    @Html.LabelFor(model=> model.UserRoles[i].Name, role.Name)
}
