我正在开发一个带有客户购买模型的REST API。我已经应用了一些验证,但是我发现对十进制类型的属性的验证不起作用,而对类型为字符串的属性的验证成功。
我的行为是,如果不添加属性(例如total),则不应用验证,并且此属性采用十进制类型的默认值,即0.0
也就是说,我有以下模型:
public class CustomerPurchase : BaseEntity
{
[Required(ErrorMessage = "PurchaseFolioRequired")]
public string Folio { get; set; }
[Required(ErrorMessage = "PurchaseIvaRequired")]
[Range(typeof(Decimal), "0", "1000000000000000000", ErrorMessage = "PurchaseInvalidVat")]
public decimal Iva { get; set; }
[Required(ErrorMessage = "PurchaseSubtotalRequired")]
[Range(typeof(Decimal), "0", "1000000000000000000", ErrorMessage = "PurchaseInvalidSubtotal")]
public decimal Subtotal { get; set; }
[Required(ErrorMessage = "PurchaseTotalRequired")]
[Range(typeof(Decimal), "0", "1000000000000000000", ErrorMessage = "PurchaseInvalidTotal")]
public decimal Total { get; set; }
[Required(ErrorMessage = "PurchaseTotalLettersRequired")]
public string TotalLetters { get; set; }
[Required(ErrorMessage = "PurchaseEmployeeRequired")]
[BsonRepresentation(BsonType.ObjectId)]
public string UserId { get; set; }
[Required(ErrorMessage = "PurchaseProductRequired")]
[MinLength(1, ErrorMessage = "PurchaseProductRequired")]
public ProductSold[] Products { get; set; }
[Required(ErrorMessage = "PurchasePaymentRequired")]
[MinLength(1, ErrorMessage = "PurchasePaymentRequired")]
public Payment[] Payments { get; set; }
[Required(ErrorMessage = "PurchaseClientRequired")]
public Client Client { get; set; }
}
这个应用程序是错误的?,或者有一个方法来严格应用这个验证。

decimal
是一个value type,所以它总是有一个默认值-0
,所以它总是通过你的验证。RequiredAttribute
的文档对此也非常清楚:RequiredAttribute
属性指定在验证表单上的字段时,该字段必须包含值。如果属性为null
、包含空字符串(“”)或仅包含空白字符,则会引发验证异常。UPD
在C# 11中添加了
required
关键字后,您可以尝试使用它来修复此问题:nwlqm0z12#
您可以编写如下代码:
