C# 从wcf服务返回的json数据不完整

我从我的WCF服务返回一个具有4个属性的NET类的JSON。问题是当它被发送到浏览器（即，Chrome，FF）时。它只返回类中的一个属性

.NET类：

[DataContract]
    public class MASInspections
    {
        [DataMember]
        public int MaintID { get; set; }
        public string MHID { get; set; }
        public DateTime MaintDate { get; set; }
        public string pdfReport { get; set; }

    }

.NET接口：

[OperationContract]
    [WebInvoke(Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Wrapped,
        UriTemplate = "GetInspectionByReach/{Reach}")]
    List<MASInspections> GetInspectionByReach(string Reach);

你知道为什么会这样吗

谢谢

这是你的问题：

[DataContract]
    public class MASInspections
    {
        [DataMember]
        public int MaintID { get; set; }
        public string MHID { get; set; }
        public DateTime MaintDate { get; set; }
        public string pdfReport { get; set; }

    }

你需要：

[DataContract]
    public class MASInspections
    {
        [DataMember]
        public int MaintID { get; set; }
        [DataMember]
        public string MHID { get; set; }
        [DataMember]
        public DateTime MaintDate { get; set; }
        [DataMember]
        public string pdfReport { get; set; }

    }

[DataContract]
    public class MASInspections
    {
        [DataMember]
        public int MaintID { get; set; }
        public string MHID { get; set; }
        public DateTime MaintDate { get; set; }
        public string pdfReport { get; set; }

    }

[DataContract]
    public class MASInspections
    {
        [DataMember]
        public int MaintID { get; set; }
        [DataMember]
        public string MHID { get; set; }
        [DataMember]
        public DateTime MaintDate { get; set; }
        [DataMember]
        public string pdfReport { get; set; }

    }
