Question

我有一个具有两种模型的视图：通用帐户e个人资料用户。

public class AccountModel
{
    [Display(Name = "UserId", Prompt = "UserId", ResourceType = typeof(Strings))]
    public string UserId { get; set; }

    [Required(ErrorMessageResourceName = "FieldRequired", ErrorMessageResourceType = typeof(Validation))]
    [EmailAddress(ErrorMessage = null, ErrorMessageResourceName = "InvalidEmail", ErrorMessageResourceType = typeof(Validation))]
    [Display(Name = "Email", Prompt = "Email", ResourceType = typeof(Strings))]
    public string Email { get; set; }

    [Required(ErrorMessageResourceName = "FieldRequired", ErrorMessageResourceType = typeof(Validation))]
    [StringLength(100, ErrorMessageResourceName = "FieldMaximumLength", ErrorMessageResourceType = typeof(Validation))]
    [Display(Name = "DisplayName", Prompt = "DisplayName", ResourceType = typeof(Strings))]
    public string DisplayName { get; set; }

    [Display(Name = "PhoneNumber", Prompt = "PhoneNumber", ResourceType = typeof(Strings))]
    public string PhoneNumber { get; set; }

    [Display(Name = "Country", Prompt = "Country", ResourceType = typeof(Strings))]
    public int CountryId { get; set; }

    public SelectList CountryList { get; set; }

}

public class UserProfileModel
{
    [Display(Name = "ID User", Prompt = "ID User")]
    public string IDUser { get; set; }

    [Required(ErrorMessageResourceName = "FieldRequired", ErrorMessageResourceType = typeof(Validation))]
    [StringLength(100, ErrorMessageResourceName = "FieldMaximumLength", ErrorMessageResourceType = typeof(Validation))]
    [Display(Name = "UserFullName", Prompt = "UserFullName")]
    public string UserFullName { get; set; }

    [Required(ErrorMessageResourceName = "FieldRequired", ErrorMessageResourceType = typeof(Validation))]
    [StringLength(16, ErrorMessageResourceName = "FieldMaximumLength", ErrorMessageResourceType = typeof(Validation))]
    [Display(Name = "Code", Prompt = "Code")]
    public string Code { get; set; }

    [Required(ErrorMessageResourceName = "FieldRequired", ErrorMessageResourceType = typeof(Validation))]
    [StringLength(250, ErrorMessageResourceName = "FieldMaximumLength", ErrorMessageResourceType = typeof(Validation))]
    [Display(Name = "Birth Place", Prompt = "BirthPlace")]
    public string BirthPlace { get; set; }

    [Display(Name = "Newsletter")]
    public bool? Newsletter { get; set; }

    [Display(Name = "Avatar", Prompt = "Avatar")]
    public string Avatar { get; set; }

}

仅当至少一个与他相关的领域被填写时，我才应验证第二个模型。
例如，如果输入BirthPlace，则还要验证第二个模型，否则仅验证第一个模型。
希望我的要求明确

如果我理解您的问题，可能您想知道如何手动验证模型。

您可以使用TryValidateModel(modelInstance);调用来手动验证所需的模型。

对于问题中提到的其他条件，可以添加if语句。

例如如果userProfileModelObject的所有字符串属性均为NULL，则验证accountModelInstance

bool isSecondObjectValid = userProfileModelObject.GetType().GetProperties()
    .Where(pi => pi.PropertyType == typeof(string))
    .Select(pi => (string)pi.GetValue(myObject))
    .Any(value => string.IsNullOrEmpty(value));


bool validationResult = false;
validationResult = !isSecondObjectValid ? 
                          TryValidateModel(accountModelInstance) :
                          TryValidateModel(userProfileModelObject);

我希望这会有所帮助。
