The RelatedExceptions property is 'readonly' for the (de)serializer.
Add a set to the property as well.
The same goes for the other private setters.
They need to be public for the serializer to set them.

I am working with ASP.NET MVC 5 Web Api.
I am having existing application with many api's.
Recently I have implemented custom JsonConverter which will convert Date as per timezone.
public class CustomInfoConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return objectType == typeof(CustomType);
}
public override bool CanRead
{
get
{
return false;
}
}
public override bool CanWrite
{
get
{
return true;
}
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var customType = (CustomType)value;
if (customType == null || null== customType.TimeZone) return;
//DateTime currentDateTime = customType.Date??DateTime.Now;
DateTime currentDateTime = DateTime.SpecifyKind(customType.Date ?? DateTime.Now, DateTimeKind.Unspecified);
DateTime userDateTime = TimeZoneInfo.ConvertTimeFromUtc(currentDateTime, customType.TimeZone);
customType.Date = userDateTime;
JsonSerializer innerSerializer = new JsonSerializer();
foreach (var converter in serializer.Converters.Where(c => !(c is CustomInfoConverter)))
{
innerSerializer.Converters.Add(converter);
}
innerSerializer.Serialize(writer, customType);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
After implementing this custom JsonConverter all api are working except one api, which is throwing below exception
{"Message":"An error has occurred.","ExceptionMessage":"The
'ObjectContent`1' type failed to serialize the response body for

You can refer to this link for more details.
The problem looks to be that, in certain situations, you are returning from WriteJson() without writing anything, specifically when customType.TimeZone == null:
var customType = (CustomType)value;
if (customType == null || null== customType.TimeZone) return;
Doing so will result in an invalid JSON object, because the property name will already have been written by the caller, resulting in:
{
"customType":
}
Trying to do this results in the exception you are seeing.
Instead, you need to prevent the property itself from being serialized. That's not possible in the converter however, it needs to be done in the containing type.
To avoid serializing a property with a null value, you should set NullValueHandling = NullValueHandling.Ignore in serializer settings, or on the property itself:
public class ContainerClass
{
[JsonProperty(NullValueHandling = NullValueHandling.Ignore)]
public CustomType CustomType { get; set; }
}
To prevent serializing your property when its TimeZone property is null, you should use conditional property serialization by adding a ShouldSerializeXXX() method to the containing type, where XXX exactly matches your property name:
public class ContainerClass
{
public CustomType CustomType { get; set; }
public bool ShouldSerializeCustomType()
{
return CustomType != null && CustomType.TimeZone != null;
}
}
The JsonConvert.DeserializeObject statement of the following code generates the exception:
try
{
string sJOutput = JsonConvert.SerializeObject(dict,
new JsonSerializerSettings()
{
ReferenceLoopHandling = ReferenceLoopHandling.Ignore
});
Debug.WriteLine(sJOutput);
dict = JsonConvert.DeserializeObject<Dictionary<Guid, MyClass>>(sJOutput);
}
catch (Exception ex)
{
Debug.WriteLine(ex.Message);
}
The exception is the following:
System.MethodAccessException was caught
HResult=-2146233072

Could anyone offer a tip on the cause of this?
I'm trying to create a simple application through Lesson 6 in N+1 Days of MvvmCross application sample. But its failed in SimpleRestService while converting json Data serialization.
private T Deserialize<T>(string responseBody)
{ // Error is here for deserilizing
var toReturn = _jsonConverter.DeserializeObject<T>(responseBody);
return toReturn;
}
My Json data through Browser:
[{"Desc":"All","Id":"0"},{"Desc":"Assigned","Id":"2"},{"Desc":"In Progress","Id":"3"},{"Desc":"Resolved","Id":"4"},{"Desc":"Closed","Id":"5"},{"Desc":"Hold","Id":"6"},{"Desc":"低","Id":"8"},{"Desc":"Waiting Approval","Id":"9"},{"Desc":"Cancelled","Id":"10"},{"Desc":"Not Resolved","Id":"8"}]
My Json data in application at responsebody:
[{\"Desc\":\"All\",\"Id\":\"0\"},{\"Desc\":\"Assigned\",\"Id\":\"2\"},{\"Desc\":\"In Progress\",\"Id\":\"3\"},{\"Desc\":\"Resolved\",\"Id\":\"4\"},{\"Desc\":\"Closed\",\"Id\":\"5\"},{\"Desc\":\"Hold\",\"Id\":\"6\"},{\"Desc\":\"低\",\"Id\":\"8\"},{\"Desc\":\"Waiting Approval\",\"Id\":\"9\"},{\"Desc\":\"Cancelled\",\"Id\":\"10\"},{\"Desc\":\"Not Resolved\",\"Id\":\"8\"}]
Error Message shows as :

You have to use the correct T for your Json call - you can't simply use BookSearchResult for all Json calls.
You can use tools like http://json2csharp.com/ to generate the CSharp classes for you - e.g.
public class RootObject
{
public string Desc { get; set; }
public string Id { get; set; }
}
which you can then use as:
var myItems = service.Deserialize<List<RootObject>>(jsonText);
I want to deserialize the body into .net classes (dictionary and list).
(so my code is transparent for xml and json)
public HttpResponseMessage Post([FromBody]IDictionary<string, object> body)
{
}
Currently I use a converter to handle nested dictionary deserialization.
class IDictionaryConverter : CustomCreationConverter<IDictionary<string, object>>
{
public override IDictionary<string, object> Create(Type objectType)
{
return new Dictionary<string, object>();
}
public override bool CanConvert(Type objectType)
{
// in addition to handling IDictionary<string, object>
// we want to handle the deserialization of dict value
// which is of type object
return objectType == typeof(object) || base.CanConvert(objectType);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.StartObject || reader.TokenType == JsonToken.Null)
return base.ReadJson(reader, objectType, existingValue, serializer);
// if the next token is not an object
// then fall back on standard deserializer (strings, numbers etc.)
return serializer.Deserialize(reader);
}
}
But nested JLists are not converted to List.
Maybe I can create a IListConverter, but is there an better way to do this?
I want in my web api only one code. not: if json do that, if xml do that...
This solves my problem:
class IDictionaryConverter : CustomCreationConverter<IDictionary<string, object>>
{
public override IDictionary<string, object> Create(Type objectType)
{
return new Dictionary<string, object>();
}
public override bool CanConvert(Type objectType)
{
// in addition to handling IDictionary<string, object>
// we want to handle the deserialization of dict value
// which is of type object
return objectType == typeof(object) || base.CanConvert(objectType);
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
if (reader.TokenType == JsonToken.StartObject || reader.TokenType == JsonToken.Null)
return base.ReadJson(reader, objectType, existingValue, serializer);
if (reader.TokenType == JsonToken.StartArray)
return serializer.Deserialize<IList<object>>(reader);
// if the next token is not an object
// then fall back on standard deserializer (strings, numbers etc.)
return serializer.Deserialize(reader);
}
}
Given the following class structure, which includes a dictionary of derived objects, how can I serialize and deserialize using NewtonSoft’s Json library? When I deserialize, I am getting an exception. It looks like it is having issues reconstituting the dictionary.
[JsonObject(MemberSerialization.OptIn)]
public class GameObject
{
[JsonProperty]
public string Id { get; set; }
[JsonProperty]
public string Name { get; set; }
[JsonProperty]
public ConcurrentDictionary<string, Component> Components;
public GameObject()
{
Components = new ConcurrentDictionary<string, Component>();
}
}
[JsonObject(MemberSerialization.OptIn)]
public class Component
{
[JsonIgnore] // Ignore circular reference
public GameObject GameObject { get; set; }
public Component()
{
}
}
[JsonObject(MemberSerialization.OptIn)]
public class TestComponent : Component
{
[JsonProperty]
public int MyProperty { get; set; }
public TestComponent()
{
}
}
var originalJson = JsonConvert.SerializeObject(srcObject, Formatting.None,
new JsonSerializerSettings
{
TypeNameHandling = TypeNameHandling.All,
TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple
});
var newObject = JsonConvert.DeserializeObject<GameObject>(originalJson,
new JsonSerializerSettings()
{
TypeNameHandling = TypeNameHandling.All,
TypeNameAssemblyFormat = FormatterAssemblyStyle.Simple
});
Exception on the DeserializeObject call:
