数据验证无法通过数据注释进行

Question

I am trying to validate the length through data annotations like this

 [DataMember]
 [StringLength(7, ErrorMessage = "ClaimNumber cannot exceed length higher than 7")]
 public string claimNumber

Still error is not thrown if string of more lenght is passed. Can any one please help with this? its with Entity framework.

Answer 1

您已经显示了一个字段，数据验证仅适用于属性。

Wcf has not data annotations validation out of the box. To add this you can use this nuget package: Wcf.AttributeValidation
