ASP.NET Core 3.x RESTful API学习记录--输入验证:IValidatableObject

作者:互联网

需要验证的Dto模型 继承于IValidatableObject

public class ValidatableMovie : IValidatableObject
{
    private const int _classicYear = 1960;

    public int Id { get; set; }

    [Required]
    [StringLength(100)]
    public string Title { get; set; }

    [DataType(DataType.Date)]
    [Display(Name = "Release Date")]
    public DateTime ReleaseDate { get; set; }

    [Required]
    [StringLength(1000)]
    public string Description { get; set; }

    [Range(0, 999.99)]
    public decimal Price { get; set; }

    public Genre Genre { get; set; }

    public bool Preorder { get; set; }

    public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
    {
        if (Genre == Genre.Classic && ReleaseDate.Year > _classicYear)
        {
            yield return new ValidationResult(
                $"Classic movies must have a release year no later than {_classicYear}.",
                new[] { nameof(ReleaseDate) });
        }
    }
}
