POJSON.Net not serializing when JsonProperty set?
text
Body
copied!<p>I'm using the latest (4.5) version of Newtonsoft Json.Net to serialize a complex type returned by my WCF web service. For some reason, if I apply the <code>[JsonProperty]</code> attribute, the fields simply don't serialize:</p> <pre><code> [DataContract] [JsonObject(MemberSerialization = Newtonsoft.Json.MemberSerialization.OptIn)] public class ScalarResult { [JsonProperty(Order = 0)] public string QueryId { get; set; } [JsonProperty(Order = 1)] public float CurrentPeriodValue { get; set; } [JsonProperty(Order = 2)] public bool HasPriorValue { get; set; } [JsonProperty(Order = 3)] public float PriorPeriodValue { get; set; } [JsonProperty(Order = 4)] public float ChangeOverPrior { get; set; } [JsonProperty(Order = 5)] public float ChangeOverPriorPercent { get; set; } </code></pre> <p>This results in a skimpy return object:</p> <pre><code>{ "SomethingElse": "why am I the only thing visible?" } </code></pre> <p>If I add <code>[DataMember]</code> to each field (which <a href="http://james.newtonking.com/json/help/index.html?topic=html/SerializationAttributes.htm" rel="nofollow">I'm not supposed to have to do</a>, according to the the Json.NET docs), then the fields show up, but the <code>(Order = x)</code> attribute is ignored, leading me to believe Json.NET might not actually be doing the serialization:</p> <pre><code>[DataContract] [JsonObject(MemberSerialization = Newtonsoft.Json.MemberSerialization.OptIn)] public class ScalarResult { [DataMember] [JsonProperty(Order = 0)] public string QueryId { get; set; } [DataMember] public string SomethingElse { get; set; } [DataMember] [JsonProperty(Order = 1)] public float CurrentPeriodValue { get; set; } [DataMember] [JsonProperty(Order = 2)] public bool HasPriorValue { get; set; } [DataMember] [JsonProperty(Order = 3)] public float PriorPeriodValue { get; set; } [DataMember] [JsonProperty(Order = 4)] public float ChangeOverPrior { get; set; } [DataMember] [JsonProperty(Order = 5)] public float ChangeOverPriorPercent { get; set; } </code></pre> <p>Which results in (<em>the wrong order</em>):</p> <pre><code>{ "ChangeOverPrior": 8, "ChangeOverPriorPercent": 0.25, "CurrentPeriodValue": 40, "HasPriorValue": true, "PriorPeriodValue": 32, "QueryId": "CitiesMonitored_count", "SomethingElse": "why am I the only thing visible?" } </code></pre> <p>Any ideas on how I can verify that Json.Net is doing the serialization and, if so, why the <code>(Order =)</code> property is being ignored?</p>
