Binding values in a @Html.ListBoxFor

Question

I'm newbies with the language asp.net and I have some difficulties to understand how works the @Html.ListBoxFor ( even if I read the doc ).

In my case I have this:

 @Html.ListBoxFor(model => model.groupe.Permissions, new SelectList(Model.permissionList,"Name"))

model.groupe.Permissions is an empty list of permission and Model.permissionList a list of permission.

I want to create a multiple select list and foreach option have Id = permission.id and value = permission.Name

How can I do something like that:

@Html.ListBoxFor(model => model.groupe.Permissions, new SelectList(Model.permissionList, id ="Id", value = "Name"))

here permissionList :

 public List<Permission> permissionList { get; set; }

and Permission :

public class Permission
    {
        public long Id { get; set; }
        public string Description { get; set; }
        public string Name { get; set; }
}
