首先它可以工作,但今天它失败了!
这就是我定义日期属性的方式:
[Display(Name = "Date")]
[Required(ErrorMessage = "Date of Submission is required.")]
[DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
[DataType(DataType.Date)]
public DateTime TripDate { get; set; }
它过去一直在工作。但是今天,当我调用相同的 ApiController 操作时:
[HttpPost]
public HttpResponseMessage SaveNewReport(TripLeaderReportInputModel model)
萤火虫报告:
ExceptionMessage:
"Property 'TripDate' on type 'Whitewater.ViewModels.Report.TripLeaderReportInputModel'
is invalid. Value-typed properties marked as [Required] must also be marked with
[DataMember(IsRequired=true)] to be recognized as required. Consider attributing the
declaring type with [DataContract] and the property with [DataMember(IsRequired=true)]."
ExceptionType
"System.InvalidOperationException"
发生了什么?那些不是[DataContract]
为了WCF
?我正在使用REST WebAPI
in MVC4
!
任何人都可以帮忙吗?请?
