DataContractJsonSerializerOperationFormatter does not deserialize using JSON.NET

Question

I am using WCF RESTful webservice and I am getting this error:

There was an error while trying to deserialize parameter http://tempuri.org/:aa. The InnerException message was 'There was an error deserializing the object of type WcfService1.Test. DateTime content '2014-05-31T18:30:00.000Z' does not start with '/Date(' and end with ')/' as required for JSON.'. Please see InnerException for more details.'. See server logs for more details. The exception stack trace is:`

at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeParameterPart(XmlDictionaryReader reader, PartInfo part) at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeParameter(XmlDictionaryReader reader, PartInfo part) at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeParameters(XmlDictionaryReader reader, PartInfo[] parts, Object[] parameters, PartInfo returnInfo, Object& returnValue) at System.ServiceModel.Dispatcher.DataContractJsonSerializerOperationFormatter.DeserializeBodyCore(XmlDictionaryReader reader, Object[] parameters, Boolean isRequest) at

Input from jQuery:

 $.ajax({ url: "Restful.svc/new/one", type: "POST", contentType: "application/json; charset=utf-8", headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' }, data: JSON.stringify({ aa: { xaaaaaa: "2014-05-31T18:30:00.000Z" } }), dataType: 'json', processData: true, success: function (msg) { alert(msg.helloWorldResult); }, error: function (msg) { var y = 0; } });

WCF Service:

 [OperationContract] [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "new/one")] String helloWorld(Test aa);

Test class:

 public class Test { [JsonProperty(ItemConverterType=typeof(IsoDateTimeConverter))] public DateTime xaaaaaa { get; set; } }

If I pass the input xaaaaaa as : /Date(new Date.valueOf().toString())/ it takes in. How do I change the default date formatter in the WCF Service to use IsoDateFormat for serialize and deserializing.

I have tried modifying the route table settings but I was not able to find most of the libraries. If I use JSON.NET it says it uses ISO format by default. How do I set it to take it in the WCF web service?

I did the exact same thing and I had to do trim off the quotes (") once the serializing was done. This was because the DataContract serializer (which is a default serializer in WCF service) serializes the final result and adds quotes around it ( Example: "\"0001-01-01T00:00:00"\", when received on client side ). Thank you @Irb it works now. — thanmai

I am using Newtonsoft to serialize the date format to hold ISODate format. I was able to solve my problem doing this:

Test.cs:

[DataContract] public class Test { public DateTime xaaaaaa { get; set; } [DataMember(Name = "xaaaaaa")] private string HiredForSerialization { get; set; } [OnSerializing] void OnSerializing(StreamingContext ctx) { this.HiredForSerialization = JsonConvert.SerializeObject(this.xaaaaaa).Replace('"',' ').Trim(); } [OnDeserialized] void OnDeserialized(StreamingContext ctx) { this.xaaaaaa = DateTime.Parse(this.HiredForSerialization); } }

jQuery:

$.ajax({ url: "Transfer.svc/new/one", type: "POST", contentType: "application/json; charset=utf-8", headers: { 'Accept': 'application/json', 'Content-Type': 'application/json' }, data: JSON.stringify({ aa: { xaaaaaa: "2014-05-31T18:30:00.000Z" } }), dataType: 'json', processData: true, success: function (msg) { tester = msg.helloWorldResult; //"2014-06-01T00:00:00+05:30" }, error: function (msg) { var y = 0; } });

Date I selected from the date picker (jQuery):

Selected date : 1st-Jun-2014

WCF Service Looks like this:

 [OperationContract] [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped, UriTemplate = "new/one")] public Test helloWorld(Test aa) { return aa; }

This works great!
