Question

不确定这是否是预期的，但这对我来说是一个惊喜..

我正在使用RegistrationViewModel强力键入视图，但是当我尝试提交表单时，验证错误地在2个位置验证。

当我输入“Test”时，电子邮件字段不会引发验证错误。
密码验证器表示密码不匹配。

任何人都知道为什么会这样吗？

ViewModel类：

 public class RegistrationViewModel
{
    public RegisterModel RegistrationData { get; set; }
    ...     
}

验证属性位于RegistrationData类的属性中：

public class RegisterModel
{
    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

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

    [Required]
    [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 6)]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm password")]
    [Compare("Password", ErrorMessage = "The Password and Confirmation password do not match.")]
    public string ConfirmPassword { get; set; }

    [Required]
    [Display(Name = "First name")]
    [StringLength(20, ErrorMessage = "First name must be between 2 and 20 characters.", MinimumLength = 2)]
    public string FirstName { get; set; }

    [Required]
    [Display(Name = "Last name")]
    [StringLength(20, ErrorMessage = "Last name must be between 2 and 20 characters.", MinimumLength = 2)]
    public string LastName { get; set; }
}

查看：

@model PropertyManager_MVC.Areas.Account.ViewModels.RegistrationViewModel
<div class="editor-field">
            @Html.TextBoxFor(m => m.RegistrationData.Email)
            @Html.ValidationMessageFor(m => m.RegistrationData.Email)
        </div>
<div class="editor-label">
            @Html.LabelFor(m => m.RegistrationData.Password)
        </div>
        <div class="editor-field">
            @Html.PasswordFor(m => m.RegistrationData.Password)
            @Html.ValidationMessageFor(m => m.RegistrationData.Password)
        </div>
        <div class="editor-label">
            @Html.LabelFor(m => m.RegistrationData.ConfirmPassword)
        </div>
        <div class="editor-field">
            @Html.PasswordFor(m => m.RegistrationData.ConfirmPassword)
            @Html.ValidationMessageFor(m => m.RegistrationData.ConfirmPassword)
        </div>

将此正则表达式添加到电子邮件属性，它将负责处理它。

  [Required]
  [DataType(DataType.EmailAddress)]
  [Display(Name = "Email address")]
  [RegularExpression("^[a-z0-9_\\+-]+(\\.[a-z0-9_\\+-]+)*@[a-z0-9]+(\\.[a-z]{2,4})$", ErrorMessage = "Not a valid email")]
  public string Email { get; set; }

在“确认密码”字段前添加必需属性。

  [Required]
  [DataType(DataType.Password)]
  [Display(Name = "Confirm password")]
  [Compare("Password", ErrorMessage = "The password and confirmation password do not match.")]
  public string ConfirmPassword { get; set; }
