即使验证失败，服务器代码也会继续执行

如果注册帐户时提供的2个密码不匹配，则验证会捕获此密码，并通知用户它们不匹配。但用户仍在创建。如果他们提供的密码少于6个字符，情况也是如此。如果验证失败，是否必须手动告诉系统不要继续？如果是这样，怎么样？即使验证失败，服务器代码也会继续执行

我的模型看起来是这样的：

[Display(Name ="Your Email")] 
    [Required(ErrorMessage="You must provide a valid Email")] 
    [EmailAddress] 
    public string email { get; set; } 

    [Required(ErrorMessage="Select a user name", AllowEmptyStrings = false)] 
    [Display(Name="User name")] 
    public string nickName { get; set; } 

    [Required(ErrorMessage="Select a password", AllowEmptyStrings = false)] 
    [Display(Name="Password")] 
    [MinLength(6, ErrorMessage="The password must be at least 6 characters long")] 
    [DataType(DataType.Password)] 
    public string password { get; set; } 

    [Required(ErrorMessage="Type your password again")] 
    [Display(Name="Confirm password")] 
    [DataType(DataType.Password)] 
    [Compare("password", ErrorMessage="The two passwords do not match")] 
    public string confirmPassword { get; set; }

的看法是这样的：

@using (Ajax.BeginForm("RegisterNewUser", "RegisterUser", new AjaxOptions { UpdateTargetId = "updaterDiv" })) 
    { 
     @Html.LabelFor(model => model.nickName) 
     @Html.TextBoxFor(model => model.nickName, new { @class = "RegisterControls" }) 
     <br /> 
     @Html.ValidationMessageFor(model => model.nickName) 
     <br /><br /> 

     @Html.LabelFor(model => model.email) 
     @Html.TextBoxFor(model => model.email, new { @class = "RegisterControls" }) 
     <br /> 
     @Html.ValidationMessageFor(model => model.email) 
     <br /><br /> 

     @Html.LabelFor(model => model.password) 
     @Html.PasswordFor(model => model.password, new { @class = "RegisterControls", id = "firstPassword" }) 
     <br /> 
     @Html.ValidationMessageFor(model => model.password) 
     <br /><br /> 

     @Html.LabelFor(model => model.confirmPassword) 
     @Html.PasswordFor(model => model.confirmPassword, new { @class = "RegisterControls" }) 
     <br /> 
     @Html.ValidationMessageFor(model => model.confirmPassword) 
     <br /><br /><br /> 
     <hr style="color: #D5E0EE; border: solid; border-style: double;" /> 

     <input type="submit" value="Create account" class="actionButtons" /> 
     <br /><br /> 
     <p style="color: red">@ViewBag.DeniedMsg</p>

和控制器：

[HttpPost] 
    public ActionResult RegisterNewUser(RegisteredUsersModel registerUserModel) 
    { 
     ViewBag.Header = "Register"; 
     string msg = ""; 

     if (!users.RegisterUser(registerUserModel.nickName, registerUserModel.email, registerUserModel.password)) 
     { 
      msg = "The provided email already exists"; 
     } 

     ViewBag.DeniedMsg = msg; 
     return PartialView("_Register");    
    }

还有一个问题我有，是该用户创建两次，所以他有两个在数据库中。任何人都可以在我的代码中看到这个问题吗？或者，也许我可能必须为此问题开一张单独的票据

即使您使用验证，控制器也不会自动执行验证。您需要使用ModelState.IsValid检查以确定您的验证是否通过：

[HttpPost] 
public ActionResult RegisterNewUser(RegisteredUsersModel registerUserModel) 
{ 
    if(ModelState.IsValid) 
    { 
     // this block is executed only when validation succeeds 
     ViewBag.Header = "Register"; 
     string msg = ""; 

     if (!users.RegisterUser(registerUserModel.nickName, registerUserModel.email, registerUserModel.password)) 
     { 
      msg = "The provided email already exists"; 
     } 

     ViewBag.DeniedMsg = msg; 
     return PartialView("_Register");    
    } 

    // this code is executed only when validation fails 
    return View(RegisteredUsersModel); // or do something else, depending on your logic 
}
