终于开始做用户部分了，先做注册
一用户 
1.1用户注册 
首先在Models里添加用户注册模型类UserRegister 继承自User，在类中new一下密码字段，并添加重复密码和验证码字段。完成后的代码 

/// <summary>
 /// 用户注册模型
 /// </summary>
 public class UserRegister : User
 {
 /// <summary>
 /// 密码
 /// </summary>
 [Display(Name="密码",Description="6-20个字符。")]
 [Required(ErrorMessage = "×")]
 [StringLength(20,MinimumLength=6,ErrorMessage = "×")]
 [DataType(DataType.Password)]
 public new string Password { get; set; }
 /// <summary>
 /// 确认密码
 /// </summary>
 [Display(Name = "确认密码", Description = "再次输入密码。")]
 [Compare("Password", ErrorMessage = "×")]
 [DataType(DataType.Password)]
 public string RePassword { get; set; }
 /// <summary>
 /// 验证码
 /// </summary>
 [Display(Name = "验证码", Description = "请输入图片中的验证码。")]
 [Required(ErrorMessage = "×")]
 [StringLength(6,MinimumLength=6,ErrorMessage = "×")]
 public string VerificationCode { get; set; }
 }

打开Controllers，在public ActionResult Register()上点右键添加视图，选强类型视图，模型类选择UserRegister 

添加完成后转到Register.cshtml编辑视图，删除掉自动生成的内容，手动输入想要的代码，完成后代码如下： 

@model CMS.Models.UserRegister

@{
 ViewBag.Title = "用户注册";
 Layout = "~/Views/Shared/_Layout.cshtml";
}
<div class="banner">
 <img src="~/Skins/Default/Images/banner.jpg" />
</div>

@using (Html.BeginForm())
{
 @Html.ValidationSummary(true)
 <div class="form">
 <dl>
  <dt>用户注册</dt>
  <dd>
  <div class="label">@Html.LabelFor(model => model.UserName)：</div>
  <div class="ctrl">@Html.EditorFor(model => model.UserName)
   @Html.ValidationMessageFor(model => model.UserName)
   @Html.DisplayDescriptionFor(model => model.UserName)
  </div>
  </dd>
  <dd>
  <div class="label">@Html.LabelFor(model => model.Gender)：</div>
  <div class="ctrl">@Html.RadioButton("Gender", 0) 男 @Html.RadioButton("Gender", 1) 女 @Html.RadioButton("Gender", 2, true) 保密
   @Html.ValidationMessageFor(model => model)
   @Html.DisplayDescriptionFor(model => model)
  </div>
  </dd>
  <dd>
  <div class="label">@Html.LabelFor(model => model.Password)：</div>
  <div class="ctrl">@Html.PasswordFor(model => model.Password)
   @Html.ValidationMessageFor(model => model.Password)
   @Html.DisplayDescriptionFor(model => model.Password)
  </div>
  </dd>
  <dd>
  <div class="label">@Html.LabelFor(model => model.RePassword)：</div>
  <div class="ctrl">@Html.PasswordFor(model => model.RePassword)
   @Html.ValidationMessageFor(model => model.RePassword)
   @Html.DisplayDescriptionFor(model => model.RePassword)
  </div>
  </dd>
  <dd>
  <div class="label">@Html.LabelFor(model => model.SecurityQuestion)：</div>
  <div class="ctrl">@Html.EditorFor(model => model.SecurityQuestion)
   @Html.ValidationMessageFor(model => model.SecurityQuestion)
   @Html.DisplayDescriptionFor(model => model.SecurityQuestion)
  </div>
  </dd>
  <dd>
  <div class="label">@Html.LabelFor(model => model.SecurityAnswer)：</div>
  <div class="ctrl">@Html.EditorFor(model => model.SecurityAnswer)
   @Html.ValidationMessageFor(model => model.SecurityAnswer)
   @Html.DisplayDescriptionFor(model => model.SecurityAnswer)
  </div>
  </dd>
  <dd>
  <div class="label">@Html.LabelFor(model => model.Email)：</div>
  <div class="ctrl">@Html.EditorFor(model => model.Email)
   @Html.ValidationMessageFor(model => model.Email)
   @Html.DisplayDescriptionFor(model => model.Email)
  </div>
  </dd>
  <dd>
  <div class="label">验证码：</div>
  <div class="ctrl">
   @Html.TextBoxFor(model => model.VerificationCode)
   @Html.ValidationMessageFor(model => model.VerificationCode)
   <img id="verificationcode" alt="" src="@Url.Action("VerificationCode", "User")" />
   <a id="trydifferent" s【文章出处:防ddos攻击】tyle="cursor:pointer">换一张</a>
  </div>
  </dd>
  <dd>
  <div class="label">注册条款：</div>
  <div class="ctrl">
   @Html.CheckBox("Agreement",new {@class="required"})
   我已阅读并同意注册条款
  </div>
  </dd>
  <dd>
  <div class="label"></div>
  <div class="ctrl">
   <input type="submit" value="注册" />
  </div>
  </dd>
 </dl>
 <div class="clear"></div>
 </div>
}
<script type="text/javascript" >
 $("#trydifferent").click(function () {
 $("#verificationcode").attr("src", "/User/VerificationCode?"+new Date());
 })
 
</script>
@section Scripts {
 @Scripts.Render("~/bundles/jqueryval")
}

下面开始写注册处理的代码。 
在Controllers，在public ActionResult Register(){return View();}下面添加一个[HttpPost]方式的Register() Action，代码如下： 

[HttpPost]
 public ActionResult Register(UserRegister userReg)
 {
  if (Session["VerificationCode"] == null || Session["VerificationCode"].ToString() == "")
  {
  Error _e = new Error { Title = "验证码不存在", Details = "在用户注册时，服务器端的验证码为空，或向服务器提交的验证码为空", Cause = "<li>你注册时在注册页面停留的时间过久页已经超时</li><li>您绕开客户端验证向服务器提交数据</li>", Solution = "返回<a href='" + Url.Action("Register", "User") + "'>注册</a>页面，刷新后重新注册" };
  return RedirectToAction("Error", "Prompt", _e);
  }
  else if (Session["VerificationCode"].ToString() != userReg.VerificationCode.ToUpper())
  {
  ModelState.AddModelError("VerificationCode", "×");
  return View();
  }
  userRsy = new UserRepository();
  if (userRsy.Exists(userReg.UserName))
  {
  ModelState.AddModelError("UserName", "用户名已存在");
  return View();
  }
  User _user = userReg;
  _user.Password = Common.Text.Sha256(userReg.Password);
  _user.RegTime = System.DateTime.Now;
  if (userRsy.Add(_user))
  {
  Notice _n = new Notice { Title = "注册成功", Details = "您已经成功注册，用户为：" + _user.UserName + " ，请牢记您的密码！", DwellTime = 5, Navigation = Url.Action("Login", "User") };
  return RedirectToAction("Notice", "Prompt", _n);
  }
  else
  {
  Error _e = new Error { Title = "注册失败", Details = "在用户注册时，发生了未知错误", Cause = "系统错误", Solution = "<li>返回<a href='" + Url.Action("Register", "User") + "'>注册</a>页面，输入正确的信息后重新注册</li><li>联系网站管理员</li>" };
  return RedirectToAction("Error", "Prompt", _e);
  }
 }

OK，运行一下看看效果 

输入完数据点注册。OK 看到注册成功的页面了

看一下数据库中也有相应记录了

注册功能就完成了。
