无法在C#中反序列化JSON结果.输入字符串格式错误不正确

Question

我试图将json输出反序列化为C#对象.JSON结果:

{"order":{"commission":3.490000,"cost":4.490000,"duration":"day","extended_hours
":false,"fees":0.000000,"class":"equity","price":1.000000,"quantity":1.000000,"r
equest_date":"2013-11-26T09:43:17.118Z","result":true,"side":"buy","status":"ok"
,"symbol":"DIS","type":"limit"}}

我从JSON派生的类:

    public class Rootobject
{
    public Order Order { get; set; }
}

public class Order
{
    public float commission { get; set; }
    public float cost { get; set; }
    public string duration { get; set; }
    public bool extended_hours { get; set; }
    public int fees { get; set; }
    public string _class { get; set; }
    public int price { get; set; }
    public int quantity { get; set; }
    public DateTime request_date { get; set; }
    public bool result { get; set; }
    public string side { get; set; }
    public string status { get; set; }
    public string symbol { get; set; }
    public string type { get; set; }
}

用于反序列化的代码(来自Newtonsoft的JSON.NET):

 Rootobject ord = JsonConvert.DeserializeObject<Rootobject>(responsebody);

我收到以下错误.

 Unhandled Exception: System.FormatException: Input string was not in a correct format.
   at Newtonsoft.Json.Utilities.ConvertUtils.Int32Parse(Char[] chars, Int32 start, Int32 length)
   at Newtonsoft.Json.JsonTextReader.ParseNumber()
   at Newtonsoft.Json.JsonTextReader.ParseValue()
   at Newtonsoft.Json.JsonTextReader.ReadInternal()
   at Newtonsoft.Json.JsonReader.ReadAsInt32Internal()
   at Newtonsoft.Json.JsonTextReader.ReadAsInt32()
   at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.ReadForType(Jso
nReader reader, JsonContract contract, Boolean hasConverter)

我已经尝试将反序列化的结果保存到一个工作正常的"动态"对象.但我不想使用动态对象来映射字段.

请指教.

注意:第三方API也会发送一个名为"class"的字段.当我尝试直接调用字段时,如何在编译时出错时调用此方法.

你有fees产权的Order定义为类int，但在JSON文本是0.00000，即float或double。我认为您可能需要将该fees属性设置为float才能正确解析它。price和quantity属性的外观也相同。
