一用戶 
1.1用戶注冊 
1.2用戶登陸 

首先在Models里添加用戶登陸模型類UserLogin，該類只要用用戶名，密碼和驗證碼三個字段。 

/// <summary> /// 用戶登陸模型 /// </summary> public class UserLogin { /// <summary> /// 用戶名 /// </summary> [Display(Name = "用戶名", Description = "4-20個字符。")] [Required(ErrorMessage = "×")] [StringLength(20, MinimumLength = 4, ErrorMessage = "×")] public string UserName { get; set; } /// <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 string Password { 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; } }

在UserController里添加Login action； 代碼看如下：

public ActionResult Login() {  return View(); } [HttpPost] public ActionResult Login(UserLogin login) {  return View(); }

使用Cookie保存登陸賬號，密碼等信息，修改public ActionResult Login(UserLogin login)。修改完成代碼如下：

[HttpPost] public ActionResult Login(UserLogin login) {  //驗證驗證碼  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，服務器端的驗證碼為空，或向服務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超時</li><li>您繞開客戶端驗證向服務器提交數據</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() != login.VerificationCode.ToUpper())  {  ModelState.AddModelError("VerificationCode", "×");  return View();  }  //驗證賬號密碼  userRsy = new UserRepository();  if (userRsy.Authentication(login.UserName, Common.Text.Sha256(login.Password)) == 0)  {  HttpCookie _cookie = new HttpCookie("User");  _cookie.Values.Add("UserName", login.UserName);  _cookie.Values.Add("Password", Common.Text.Sha256(login.Password));  Response.Cookies.Add(_cookie);  return RedirectToAction("Default","User");  }  else  {  ModelState.AddModelError("Message", "登陸失敗！");  return View();  } }

在public ActionResult Login() 上右鍵添加強類型視圖
