如何有条件地要求 OWNED 类的属性

Question

如何使类的属性仅在某些时候需要。使用 ADDRESS 类，我的模型将需要公司办公室的属性。对于场外设施（可能不存在），我需要将属性设置为可选。

我想将 CorpOffice 街道、城市、州和邮政编码设为必填。当使用 Validator.TryValidateObject(...) 验证整个应用程序时，我试图让验证结果集合具有缺少的属性。

[Owned]
public class Address : BaseModel
{
    public string? Street { get => _Street; set { _Street = value; NotifyPropertyChanged(nameof(Street)); } }

    private string? _Street;
    

    public string? Mailing { get => _Mailing; set { _Mailing = value; NotifyPropertyChanged(nameof(Mailing)); } }

    private string? _Mailing;


    public string? City { get => _City; set { _City = value; NotifyPropertyChanged(nameof(City)); } }

    private string? _City;


    public virtual State? State { get => _State; set { _State = value; NotifyPropertyChanged(nameof(State)); } }

    private State? _State;


    public int? Zip { get => _Zip; set { _Zip = value; NotifyPropertyChanged(nameof(Zip)); } }

    private int? _Zip;


    public int? Zip4 { get => _Zip4; set { _Zip4 = value; NotifyPropertyChanged(nameof(Zip4)); } }

    private int? _Zip4;
}


public class Application
{
    [Required]
    public Address CorpOffice { get; set; }

    public Address Offsite_Facility { get; set; }
}

所以根据pjs对我的问题的评论，这就是我想出的。

public class Application : IValidatableObject
{

    // Other properties that require validation decorated with the [Required] attribute 

    public Address CorpOffice { get; set; }

    public Address Offsite_Facility { get; set; }



    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        var results = new List<ValidationResult>();

        if (string.IsNullOrEmpty(CorpOffice.Street))
    results.Add(new ValidationResult("Street address is required", ["CorpOffice.Street"]));

        if (string.IsNullOrEmpty(CorpOffice.City))
    results.Add(new ValidationResult("City is required", ["CorpOffice.City"]));

        if (CorpOffice.State == null || CorpOffice.State.StateId == 0)
    results.Add(new ValidationResult("State is required", ["CorpOffice.State"]));

        if (CorpOffice.Zip == null || CorpOffice.Zip == 0)
    results.Add(new ValidationResult("Zip Code is required", ["CorpOffice.Zip"]));

        if (CorpOffice.Zip > 99999)
    results.Add(new ValidationResult("Zip Code cannot be more than 5 numbers", ["CorpOffice.Zip"]));

        if(CorpOffice.Zip4 > 9999)
    results.Add(new ValidationResult("Zip + 4 cannot be more than 4 numbers", ["CorpOffice.Zip4"]));


        if (string.IsNullOrEmpty(Offsite_Facility.Street))
    results.Add(new ValidationResult("Street address is required", ["Offsite_Facility.Street"]));

        if (string.IsNullOrEmpty(Offsite_Facility.City))
    results.Add(new ValidationResult("City is required", ["Offsite_Facility.City"]));

        if (Offsite_Facility.State == null || Offsite_Facility.State.StateId == 0)
    results.Add(new ValidationResult("State is required", ["Offsite_Facility.State"]));

        if (Offsite_Facility.Zip == null || Offsite_Facility.Zip == 0)
    results.Add(new ValidationResult("Zip Code is required", ["Offsite_Facility.Zip"]));

        if (Offsite_Facility.Zip > 99999)
    results.Add(new ValidationResult("Zip Code cannot be more than 5 numbers", ["Offsite_Facility.Zip"]));

        if (Offsite_Facility.Zip4 > 9999)
    results.Add(new ValidationResult("Zip + 4 cannot be more than 4 numbers", ["Offsite_Facility.Zip4"]));

        return results;
    }
}

然后我按照我的逻辑运行检查

...
ValidationResults = [];

// If there are validation errors, fill the results collection
Validator.TryValidateObject(NewApplication, new ValidationContext(NewApplication), ValidationResults, validateAllProperties: true);

 // Run the custom validation
 foreach(var val in NewApplication.Validate(new ValidationContext(NewApplication)))
     ValidationResults.Add(val);
...
