I am trying to deserialize a json output to a C# object. JSON result:
{"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"}}
My derived class from JSON:
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; }
}
Code used to deserialize (JSON.NET from Newtonsoft) :
Rootobject ord = JsonConvert.DeserializeObject<Rootobject>(responsebody);
I am getting the following error.
Unhandled Exception: System.FormatException: Input string was not in a correct format.
at Newtonsoft.Json.Utilities.ConvertUtils.Int32Parse(Char[] chars, Int32 start, Int32 length)

I have tried saving the deserialized result to a "dynamic" object which works fine. But I do not want to use the dynamic object for mapping the fields.
Please advice.
Note: Also the 3rd party API is sending a field called "class". How do I call this as I get compile-time error when I try to directly call the field.
You have the fees
property in the Order
class defined as an int
but in the JSon text it is 0.00000
, i.e. a float
or double
. I think you may need to make the fees
property into a float
in order to parse it properly. Looks the same for the price
and quantity
properties too.
