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。
