Deserializing JSON data to C# using JSON.NET

Use

var rootObject =  JsonConvert.DeserializeObject<RootObject>(string json);

Create your classes on JSON 2 C#

Json.NET documentation: Serializing and Deserializing JSON with Json.NET

Have you tried using the generic DeserializeObject method?

JsonConvert.DeserializeObject<MyAccount>(myjsondata);

Any missing fields in the JSON data should simply be left NULL.

UPDATE:

If the JSON string is an array, try this:

var jarray = JsonConvert.DeserializeObject<List<MyAccount>>(myjsondata);

jarray should then be a List<MyAccount>.

ANOTHER UPDATE:

The exception you're getting isn't consistent with an array of objects- I think the serializer is having problems with your Dictionary-typed accountstatusmodifiedby property.

Try excluding the accountstatusmodifiedby property from the serialization and see if that helps. If it does, you may need to represent that property differently.

Documentation: Serializing and Deserializing JSON with Json.NET

You can use:

JsonConvert.PopulateObject(json, obj);

here: json is the json string,obj is the target object. See: example

Note: PopulateObject() will not erase obj's list data, after Populate(), obj's list member will contains its original data and data from json string
