在一个 MVC 项目中,我有一个具有(比方说)10 个属性的类,都是必需的。在用户选择的情况下,我必须验证一次只有 3 个属性,其他时间验证所有属性。

这些是我的 Patient 类的属性:

    [Required(ErrorMessage = "Last Name is required")]
    [StringLength(50)]
    public string responsibleLastName;

    [Required(ErrorMessage = "First Name is required")]
    [StringLength(50)]
    public string responsibleFirstName;

    [Required(ErrorMessage = "Address is required")]
    [StringLength(50)]
    public string responsibleAddressLine1;

    [Required(ErrorMessage = "City is required")]
    [StringLength(50)]
    public string responsibleCityName;

    [Required(ErrorMessage = "State is required")]
    [StringLength(2)]
    public string responsibleStateCode;

    [Required(ErrorMessage = "Zip Code is required")]
    [StringLength(10)]
    public string responsiblePostalZoneOrZIPCode;

    [Required(ErrorMessage = "Birth Date is required")]
    public DateTime responsibleBirthDate;

    [Required(ErrorMessage = "Gender is required")]
    public string responsibleGenderCode;

    [Required(ErrorMessage = "Home Phone is required")]
    [StringLength(10)]
    public string responsibleHomePhone;

在保存之前,在控制器中我正在进行验证:

 if (firstCondition)  //partial validation
        {      if (!ModelState.IsValidField("responsibleLastName"))
            {
                ModelState.AddModelError("responsibleLastName", "Last Name is required");
            isOK = false;
             }
              //... and 2 more validation

              //finally I check the isOK value

               if (!isOK)
                  return PartialView("firstCondition", model);
               else
                  // do something

        }
else {   //validate all the properties from the model
    if (!ModelState.IsValid)
            return PartialView("secondCondition", model);   
    else
           //do something
}

在第一种情况下,我的消息对于这 3 个属性 + 类的所有错误消息都是重复的。

ModelState.IsValidField 正在调用 Model.IsValid 并获取每个属性的 ModelValidationResult 列表,然后检查我想要的字段的结果?为什么消息重复?

我想使用模型验证工具,所以我不想手动验证值

//NOT
 if (!model.responsibleLastName == "")
            {
                ModelState.AddModelError("responsibleLastName", "Last Name is required");
            isOK = false;
             }

先感谢您。
