c# - MVC 比较属性在服务器端不起作用

Question

我有以下代码

[Required]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)]
[Display(Name = "Password")]
[DataType(DataType.Password)]
public string Password { get; set; }

[Required]
[DataType(DataType.Password)]
[Display(Name = "Confirm password")]
[StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)]
[Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
public string ConfirmPassword { get; set; }

当我显示表单时，客户端验证有效，但当我在服务器端测试时，它始终有效(尝试使用 Password=pass1234 和 ConfirmPassword=nonmatchingpassword)

我还尝试了一些其他属性，例如 http://foolproof.codeplex.com/ 中的 EqualTo但同样的问题。

我已经包含了方法

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Register(RegisterViewModel model) 
{
    if (WebSecurity.IsAuthenticated)
    {
        return RedirectToAction("Index", "Home");
    }

    if (ModelState.IsValid) 
    {
        // register user...
    }

    model.Countries = this.Countries.FindAll().OrderBy(c => c.Name);
    return View(model);
}

这就是我渲染它的方式

@using (Html.BeginForm(null, null, FormMethod.Post, new { @class = "form", @id = "register-form" }))
{
@Html.AntiForgeryToken()
<ul class="form-fields">
    ...
    <li class="form-field">
        @Html.LabelFor(m => m.Password)
        @Html.ValidationMessageFor(m => m.Password)
        @Html.EditorFor(m => m.Password)
    </li>
    <li class="form-field">
        @Html.LabelFor(m => m.ConfirmPassword)
        @Html.ValidationMessageFor(m => m.ConfirmPassword)
        @Html.EditorFor(m => m.ConfirmPassword)
    </li>
    ...     
    <li class="form-actions"> 
        <button class="submit">register</button>
    </li>
</ul>
}

任何想法可能是错误的？我正在使用 MVC4 RC。

Microsoft 在其默认的 MVC 项目模板中是这样做的:

    [PropertiesMustMatch( "Password", "ConfirmPassword", ErrorMessage = "The                    password and confirmation password do not match." )]
    public class RegisterModel
    {
        [Required]
        [DisplayName( "User name" )]
        public string UserName { get; set; }

        [Required]
        [DataType( DataType.EmailAddress )]
        [DisplayName( "Email address" )]
        public string Email { get; set; }

        [Required]
        [ValidatePasswordLength]
        [DataType( DataType.Password )]
        [DisplayName( "Password" )]
        public string Password { get; set; }

        [Required]
        [DataType( DataType.Password )]
        [DisplayName( "Confirm password" )]
        public string ConfirmPassword { get; set; }
}

我不确定您是如何进行服务器端测试的。如果这对您不起作用，也许您可​​以发布失败的测试？
