ASP.NET 验证属性

Question

在我的模型 RegisterViewModel on Password 属性中，我做了两个验证属性。在这种情况下，我使用通常的 MVC 和 jQuery 验证。问题是验证消息显示唯一的

[RegularExpression(@"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[#$^+=!*()@%&]).{0,}$", ErrorMessage = CommonConstants.CREATE_USER_PASSWORD_ERROR)]

如果密码不在 6-15 个字符之间，我希望显示来自该属性的消息

[StringLength(15, ErrorMessage = "The password must be at least {2} and at max {1} characters long.", MinimumLength = 6)]

密码属性：

    [Required(ErrorMessage = "Password field is required")]
            [StringLength(15, ErrorMessage = "The password must be at least {2} and at max {1} characters long.", MinimumLength = 6)]
[RegularExpression(@"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[#$^+=!*()@%&]).{6,15}$",ErrorMessage = CommonConstants.CREATE_USER_PASSWORD_ERROR)]
            [DataType(DataType.Password)]
            [Display(Name = "Password")]
            public string Password { get; set; }

这是视图：

@using (Html.BeginForm("Create", "Users", FormMethod.Post))
{
    @Html.AntiForgeryToken();
<div class="form-horizontal">
    <h4>Contacts</h4>
    <hr />

    @Html.HiddenFor(x => Model.RegisterViewModel.OrganizationId)
