MVC4制作网站中怎样实现用户注册

MVC4制作网站中怎样进行用户注册，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

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

/// 
 /// 用户注册模型 /// 
 public class UserRegister : User { /// 
 /// 密码 /// 
 [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; } /// 
 /// 确认密码 /// 
 [Display(Name = "确认密码", Description = "再次输入密码。")] [Compare("Password", ErrorMessage = "×")] [DataType(DataType.Password)] public string RePassword { get; set; } /// 
 /// 验证码 /// 
 [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";}
 
@using (Html.BeginForm()){ @Html.ValidationSummary(true) 
 
  
用户注册
  
  
@Html.LabelFor(model => model.UserName)：
  
@Html.EditorFor(model => model.UserName)   @Html.ValidationMessageFor(model => model.UserName)   @Html.DisplayDescriptionFor(model => model.UserName)  
  
  
  
@Html.LabelFor(model => model.Gender)：
  
@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)  
  
  
  
@Html.LabelFor(model => model.Password)：
  
@Html.PasswordFor(model => model.Password)   @Html.ValidationMessageFor(model => model.Password)   @Html.DisplayDescriptionFor(model => model.Password)  
  
  
  
@Html.LabelFor(model => model.RePassword)：
  
@Html.PasswordFor(model => model.RePassword)   @Html.ValidationMessageFor(model => model.RePassword)   @Html.DisplayDescriptionFor(model => model.RePassword)  
  
  
  
@Html.LabelFor(model => model.SecurityQuestion)：
  
@Html.EditorFor(model => model.SecurityQuestion)   @Html.ValidationMessageFor(model => model.SecurityQuestion)   @Html.DisplayDescriptionFor(model => model.SecurityQuestion)  
  
  
  
@Html.LabelFor(model => model.SecurityAnswer)：
  
@Html.EditorFor(model => model.SecurityAnswer)   @Html.ValidationMessageFor(model => model.SecurityAnswer)   @Html.DisplayDescriptionFor(model => model.SecurityAnswer)  
  
  
  
@Html.LabelFor(model => model.Email)：
  
@Html.EditorFor(model => model.Email)   @Html.ValidationMessageFor(model => model.Email)   @Html.DisplayDescriptionFor(model => model.Email)  
  
  
  
验证码：
  
   @Html.TextBoxFor(model => model.VerificationCode)   @Html.ValidationMessageFor(model => model.VerificationCode)      换一张  
  
  
  
注册条款：
  
   @Html.CheckBox("Agreement",new {@class="required"})   我已阅读并同意注册条款  
  
  
  
  
     
  
 
 
 
}@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 = "
你注册时在注册页面停留的时间过久页已经超时
您绕开客户端验证向服务器提交数据
", Solution = "返回注册页面，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 = "
返回注册页面，输入正确的信息后重新注册
联系网站管理员
" };  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。
