WCF Rest receiving object as null

Question

I have a WCF service that expects an object as input.

[WebInvoke(Method = "POST", UriTemplate = "SaveItem", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)] [OperationContract] public string SaveItem(Item item) { string retValue; using (var business = new ItemBusiness()) { retValue = business.SaveItem(item).ToString(); } return retValue; } 

The class of the element is as follows.

  [DataContract] public class Item { [DataMember] public string UserId { get; set; } [DataMember] public string Name { get; set; } [DataMember] public string Description { get; set; } [DataMember] public string Cost { get; set; } //[DataMember] //public string AvailableQunatity { get; set; } [DataMember] public string IsNegotiable { get; set; } [DataMember] public string LocationLat { get; set; } [DataMember] public string LocationLong { get; set; } [DataMember] public string Condition { get; set; } [DataMember] public string DeliveryType { get; set; } [DataMember] public string PostalCode { get; set; } [DataMember] public string Category { get; set; } } 

I am passing json from an android app.

{"UserId": "1", "Name": "1", "Description": "1", "Cost": "1", "IsNegotiable": "1", "LocationLat": "1", " LocationLong ":" 1 "," Status ":" 1 "," DeliveryType ":" 1 "," PostalCode ":" 1 "," Category ":" 13 "}

but the WCF method gets the element as null, but not sure why.

Any help would be appreciated.

thanks.

EDIT

finally working ... changed WebMessageBodyStyle.Wrapped to WebMessageBodyStyle.Bare

Thank you for sharing your decision. I need the WebMessageBodyStyle.Bare bit, but my other problem was that my JSON was wrapped in the parent "node" on sentences on other sites, for example:

 Not Working --> {"MethodParamName":[{"prop1":"value1","prop2":"value2"}]} 

But my JSON was always null. However, as soon as I reset the “parent node” of my JSON, my WCF was finally able to read the object:

 Working --> {"prop1":"value1","prop2":"value2"}
