创建Model

public class Order
{
public int id { get; set; }
public DateTime Time { get; set; }
public decimal Price { get; set; }

public virtual Login Logins { get; set; }
}

创建用户登录Model

public class Login
{
public int id { get; set; }
public string name { get; set; }
public string password { get; set; }

public virtual ICollection<Order> Orders { get; set; }
}

创建上下文类

public class Dbcontext:DbContext
{
public DbSet<Login> Logins { get; set; }
public DbSet<Order> Orders { get; set; }
}

同志！！！！！！！记得修改web.config里面的数据库链接

创建Home控制器，选择读写，删除不需要的部分，模板选择Order，上下文类选择

private Dbcontext db = new Dbcontext();

public ActionResult Index()
{
return View(db.Orders.ToList());
}

public ActionResult Details(int id = 0)
{
Order order = db.Orders.Find(id);
if (order == null)
{
return HttpNotFound();
}
return View(order);
}

创建一个Account控制器

public class AccountController : Controller
{
//
// GET: /Account/
Dbcontext db = new Dbcontext();

[HttpGet]
public ActionResult Login()
{

return View();
}

[HttpPost]
public ActionResult Login(Login User)
{
var user = db.Logins.Where(a => a.name == User.name && a.password == User.password).FirstOrDefault();
if (user != null)
return RedirectToAction("Index", "Home");
return View();
}

}

protected override void Dispose(bool disposing)
{
db.Dispose();
base.Dispose(disposing);
}
}

创建Login视图，选择Create

@model _3.Models.Login

@{
ViewBag.Title = "Login";
}

<h2>Login</h2>

@using (Html.BeginForm()) {
@Html.ValidationSummary(true)

<fieldset>
<legend>Login</legend>

<div class="editor-label">
@Html.LabelFor(model => model.name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.name)
@Html.ValidationMessageFor(model => model.name)
</div>

<div class="editor-label">
@Html.LabelFor(model => model.password)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.password)
@Html.ValidationMessageFor(model => model.password)
</div>

<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}

<div>
@Html.ActionLink("Back to List", "Index")
</div>

@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}

创建Index视图，将布局改成考题所需

@model IEnumerable<_3.Models.Order>

@{
ViewBag.Title = "Index";
}

<h2>Index</h2>
你的订单如下：
@foreach (var item in Model)
{
<p>bianhao: @(item.id)</p>
@Html.ActionLink("xxxx", "details", new {id=@item.id })
<hr/>
}
