這篇文章主要為大家詳細介紹了MVC4制作網(wǎng)站教程，用戶注冊功能的實現(xiàn)代碼，具有一定的參考價值，感興趣的小伙伴們可以參考一下

終于開始做用戶部分了，先做注冊
一用戶
1.1用戶注冊
首先在Models里添加用戶注冊模型類UserRegister 繼承自User，在類中new一下密碼字段，并添加重復(fù)密碼和驗證碼字段。完成后的代碼

/// <summary>
 /// 用戶注冊模型
 /// </summary>
 public class UserRegister : User
 {
 /// <summary>
 /// 密碼
 /// </summary>
 [Display(Name="密碼",Description="6-20個字符。")]
 [Required(ErrorMessage = "×")]
 [StringLength(20,MinimumLength=6,ErrorMessage = "×")]
 [DataType(DataType.Password)]
 public new string Password { get; set; }
 /// <summary>
 /// 確認密碼
 /// </summary>
 [Display(Name = "確認密碼", Description = "再次輸入密碼。")]
 [Compare("Password", ErrorMessage = "×")]
 [DataType(DataType.Password)]
 public string RePassword { get; set; }
 /// <summary>
 /// 驗證碼
 /// </summary>
 [Display(Name = "驗證碼", Description = "請輸入圖片中的驗證碼。")]
 [Required(ErrorMessage = "×")]
 [StringLength(6,MinimumLength=6,ErrorMessage = "×")]
 public string VerificationCode { get; set; }
 }

打開Controllers，在public ActionResult Register()上點右鍵添加視圖，選強類型視圖，模型類選擇UserRegister

添加完成后轉(zhuǎn)到Register.cshtml編輯視圖，刪除掉自動生成的內(nèi)容，手動輸入想要的代碼，完成后代碼如下：

@model CMS.Models.UserRegister

@{
 ViewBag.Title = "用戶注冊";
 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>用戶注冊</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">驗證碼：</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" style="cursor:pointer">換一張</a>
  </div>
  </dd>
  <dd>
  <div class="label">注冊條款：</div>
  <div class="ctrl">
   @Html.CheckBox("Agreement",new {@class="required"})
   我已閱讀并同意注冊條款
  </div>
  </dd>
  <dd>
  <div class="label"></div>
  <div class="ctrl">
   <input type="submit" value="注冊" />
  </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")
}

下面開始寫注冊處理的代碼。
在Controllers，在public ActionResult Register(){return View();}下面添加一個[HttpPost]方式的Register() Action，代碼如下：

[HttpPost]
 public ActionResult Register(UserRegister userReg)
 {
  if (Session["VerificationCode"] == null || Session["VerificationCode"].ToString() == "")
  {
  Error _e = new Error { Title = "驗證碼不存在", Details = "在用戶注冊時，服務(wù)器端的驗證碼為空，或向服務(wù)器提交的驗證碼為空", Cause = "<li>你注冊時在注冊頁面停留的時間過久頁已經(jīng)超時</li><li>您繞開客戶端驗證向服務(wù)器提交數(shù)據(jù)</li>", Solution = "返回<a href='" + Url.Action("Register", "User") + "'>注冊</a>頁面，刷新后重新注冊" };
  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", "用戶名已存在");
  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 = "注冊成功", Details = "您已經(jīng)成功注冊，用戶為：" + _user.UserName + " ，請牢記您的密碼！", DwellTime = 5, Navigation = Url.Action("Login", "User") };
  return RedirectToAction("Notice", "Prompt", _n);
  }
  else
  {
  Error _e = new Error { Title = "注冊失敗", Details = "在用戶注冊時，發(fā)生了未知錯誤", Cause = "系統(tǒng)錯誤", Solution = "<li>返回<a href='" + Url.Action("Register", "User") + "'>注冊</a>頁面，輸入正確的信息后重新注冊</li><li>聯(lián)系網(wǎng)站管理員</li>" };
  return RedirectToAction("Error", "Prompt", _e);
  }
 }

OK，運行一下看看效果
