自定义密码ValidationMessageFor

Question

您好我正在尝试为身份验证系统创建自定义密码验证，具体取决于使用MVC设置的密码设置。

在系统的管理区域中，用户可以选择密码必须遵守的设置。我希望验证消息能够反映出来并且仅在密码输入错误时显示，但目前它始终显示。

这是我的观点：

@model Domain.Authentication.Users.RegisterDTO

@helper passwordPolicySpecs()
{
    Services.Settings.Interfaces.ISettingsService _service = Core.Context.Engine.Resolve<Services.Settings.Interfaces.ISettingsService>();
    string passwordWarning = "Password invalid. Password must contain: ";
    passwordWarning = (_service.GetSettingValue<Services.Authentication.Policies.PasswordPolicySettings, bool>(x => x.PasswordMustBeMinimumLength)) ? passwordWarning + ("At least " + _service.GetSettingValue<Services.Authentication.Policies.PasswordPolicySettings, int>(x => x.PasswordLength).ToString() + " letters. ") : passwordWarning + "";
    passwordWarning = (_service.GetSettingValue<Services.Authentication.Policies.PasswordPolicySettings, bool>(x => x.PasswordMustContainANumber)) ? passwordWarning + "A number. " : passwordWarning + "";
    passwordWarning = (_service.GetSettingValue<Services.Authentication.Policies.PasswordPolicySettings, bool>(x => x.PasswordMustContainASpecialCharacter)) ? passwordWarning + "A special character. " : passwordWarning + "";
    passwordWarning = (_service.GetSettingValue<Services.Authentication.Policies.PasswordPolicySettings, bool>(x => x.PasswordMustContainLowerCase)) ? passwordWarning + "A lower case letter. " : passwordWarning + "";
    passwordWarning = (_service.GetSettingValue<Services.Authentication.Policies.PasswordPolicySettings, bool>(x => x.PasswordMustContainUpperCase)) ? passwordWarning + "An upper case letter. " : passwordWarning + "";
    @Html.ValidationMessageFor(model => model.Password, passwordWarning, new { @class = "text-danger" })
}

<div class="reset-password-page">

                @Html.ValidationSummary(true)
