从本章开始，将介绍Asp.NetMVC4中的model部分

model binding

从sample开始

1. 准备Model

 public class Person
    {
       public int PersonId { get; set; }
       public string FirstName { get; set; }
       public string LastName { get; set; }
       public DateTime BirthDate { get; set; }
       public Address HomeAddress { get; set; }
       public bool IsApproved { get; set; }
       public Role Role { get; set; }
    }
   public class Address
    {
       public string Line1 { get; set; }
       public string Line2 { get; set; }
       public string City { get; set; }
       public string PostalCode { get; set; }
       public string Country { get; set; }
    }
   public enum Role
    {
       Admin,
       User,
       Guest
}

2. 准备Controller

   public class PersonController : Controller
    {
       //
       // GET: /Person/
       private readonly Person[] _personData = {
new Person {FirstName = "Iori",LastName = "Lan", Role = Role.Admin,PersonId = 1},
new Person {FirstName = "Edwin",LastName = "Sanderson", Role = Role.Admin,PersonId = 2},
new Person {FirstName = "John",LastName = "Griffyth", Role = Role.User,PersonId = 3},
new Person {FirstName = "Tik",LastName = "Smith", Role = Role.User,PersonId = 4},
new Person {FirstName = "Anne",LastName = "Jones", Role = Role.Guest,PersonId = 5}
};
       public ActionResult PersonInfo(int id)
       {
           Person dataItem = _personData.Where(p => p.PersonId == id).First();
           return View("PersonInfo", dataItem);
       }
 
}

3. View(PersonInfo.cshtml)

@model MVCModel.Models.Person
@{
ViewBag.Title = "Index";
}
<h2>Person</h2>
<div><label>ID:</label>@Html.DisplayFor(m=> m.PersonId)</div>
<div><label>FirstName:</label>@Html.DisplayFor(m => m.FirstName)</div>
<div><label>LastName:</label>@Html.DisplayFor(m => m.LastName)</div>
<div><label>Role:</label>@Html.DisplayFor(m=> m.Role)</div>

4. 运行

Scenario 1 : 不传递id
