datacontractjsonserializer

OK, I am using the System.Runtime.Serialization and the DataContractJsonSerialization . The problem is that in the request I send a value of a property with the & character. Say, AT&T , and I get a response with error: Invalid JSON Data . I thought that the escaping would be done inside the library but now I see that the serialization is left untouched the ampersand & character. Yes, for a JSON format this is valid. But it will be a problem to my POST request since I need to send this to a server that if contains an ampersand will response with error, hence here I am. HttpUtility.HtmlEncode is

I grabbed an example off of this SO question , and built my own custom Google Maps object used for deserializing the json object. Now the code works like a champ, but I just need an explanation on why/how it works. Does the serializer "try" to match up names, or is something else going on. What exactly is this doing? Here's the working code. Imports System.Net Imports System.Web Imports System.Runtime.Serialization Imports System.Runtime.Serialization.Json Imports System.Web.Script.Serialization Namespace Utilities.Apis Public NotInheritable Class GoogleGeolocate Private Const googleUrl As

I use the following class to exchange JSON data over two ASP.NET services : [DataContract] public class Filter { [DataMember] public string Name {get; set;} [DataMember] public FilterOperator Operator {get; set;} [DataMember] public object Value {get; set;} } Here is the problem : if I set a DateTime inside Value , it will be deserialized as string : Value = "/Date(1476174483233+0200)/" This is probably because deserializer has no clue to know what was the type of the value when serialized initially : JSON = {"Value":"\/Date(1476174483233+0200)\/"} As explained here ,

I'm developing a Windows 10 UWP app and can't seem to get rid of this error: "An exception of type 'System.Runtime.Serialization.SerializationException' occurred in mscorlib.ni.dll but was not handled in user code" I'm using the Rest API to retrieve values from a Data Store on Parse and instantiate objects. Here's what my Class looks like public class ImageTest { public class Image { public string __type { get; set; } public string name { get; set; } public string url { get; set; } } public class Result { public string createdAt { get; set; } public Image image { get; set; } public string name

I am using DataContractJsonSerializer to serialize my custom object to JSON. But i want to skip the data members whose values are null . If DataMember is null that node should not come in JSON string. How can I achieve this? Give me a simple code snippet to work with. You can use the EmitDefaultValue = false property in the [DataMember] attribute. For members marked with that attribute, their values will not be output. [DataContract] public class MyType { [DataMember(EmitDefaultValue = false)] public string Prop1 { get; set; } [DataMember(EmitDefaultValue = false)] public string Prop2 { get;

I'm using the HL7.Fhir nuget package 0.9.3 created by Ewout Kramer. I am tying it up with ASP.NET Web API, but unfortunately the built in JSON serialization isn't generating the JSON correctly. It contains lots of this: "<IdentifierElement>k__BackingField" As suggested by the framework, this code works... public HttpResponseMessage GetConformance() { var conformance = new Conformance(); var json = FhirSerializer.SerializeResourceToJson(conformance); return new HttpResponseMessage{Content = new StringContent(json)}; } but this will become quite repetitive and isn't following the "by convention"
