если л вызовите функцию:

var test= DeserializeAccountRunOns(goldString);

л получаю исключение: Невозможно привести объект типа 'System.Object[]' к типу "MyProject.Class" Есть идеи? Заранее спасибо.

Вашего JSON является списком (массив) не объект так первой задачи вы бросаете список JSON (массив) для объекта класса. –

@ParthTrivedi, если l меняет значение на RunOns myClass = new JavaScriptSerializer(). Deserialize (json); Я все еще получаю сообщение об ошибке «MyPropert не поддерживается для десериализации массива». – Muzingaye

JArray jsonResponse = JArray.Parse(goldString); 

foreach (var item in jsonResponse) 
{ 
    JObject jRaces = (JObject)item["races"]; 
    foreach (var rItem in jRaces) 
    { 
     string rItemKey = rItem.Key; 
     JObject rItemValueJson = (JObject)rItem.Value; 
     Races rowsResult = Newtonsoft.Json.JsonConvert.DeserializeObject<Races>(rItemValueJson.ToString()); 
    } 
}

Может попробовать с:

JArray jsonResponse = JArray.Parse(goldString); 

foreach (var item in jsonResponse) 
{ 
    foreach (var rItem in jRaces) 
    { 
     string rItemKey = rItem.Key; 
     JObject rItemValueJson = (JObject)rItem.Value; 
     Races rowsResult = item.Value<JObject>("races").ToObject<Races>(); 
    } 
}
