how to parse json list at c#

Question

How to parse this json list at c# ? I have read this list at my service side.I using web api .

[
{ "Id":1,
  "Adjustment":{
    "CardNumber": "1234567895678",
    "TimeStamp": "2016-06-14 12:00:56",
    "Point": -13.09
    }
},
{ "Id":2,
  "Adjustment":{
    "CardNumber": "2345673245689",
    "TimeStamp": "2016-06-14 12:05:43",
    "Point": 2.3
    }
}
] 

I done this way but it is not working :How can I fixed my code? Do you have any suggestions ?I sent to request body with Fiddler.

public object InsertNewCustomer([FromBody] object value)
{
    var returns = new List<object>();

    if (value == null)
    {
        returns.Add(new { ReturnCode = "-1" });

        return Json(returns, JsonRequestBehavior.AllowGet).Data;
    }
    var jsonstr = @value.ToString();

    var jsonVal = JArray.Parse(jsonstr);



    Cariler newcustomer = new Cariler();

    using (TransactionScope scope = new TransactionScope())
    {

        foreach (JObject root in jsonVal)
        {
            foreach (KeyValuePair<String, JToken> app in root)
            {

                var card = (String)app.Value["CardNumber"];
                var time = (String)app.Value["TimeStamp"];
                var point = (byte)app.Value["Point"];

                newcustomer.CardNum = card;
                newcustomer.Time = time;
                newcustomer.Point = point;
                context.Cariler.Add(newcustomer);
                context.SaveChanges();
            }
        }


        scope.Complete();
        returns.Add(new { ReturnCode = "0" });

        return Json(returns, JsonRequestBehavior.AllowGet).Data;
    }
}

Giving this error :

Solution 1

On json2csharp.com you can generate classes for your JSON, for your JSON they can look like:

public class Adjustment
{
    public string CardNumber { get; set; }
    public string TimeStamp { get; set; }
    public double Point { get; set; }
}

public class RootObject
{
    public int Id { get; set; }
    public Adjustment Adjustment { get; set; }
}

And then deserialise it:

List<RootObject> o = JsonConvert.DeserializeObject<List<RootObject>>(string json)

Solution 2

Taking the json structure in your question, http://json2csharp.com/ gives us the following:

public class Adjustment
{
    public string CardNumber { get; set; }
    public string TimeStamp { get; set; }
    public double Point { get; set; }
}

public class RootObject
{
    public int Id { get; set; }
    public Adjustment Adjustment { get; set; }
}

Just accept them as an array in your controller action:

public class SomeController : ApiController
{
    public IHttpActionResult Post([FromBody] RootObject[] values)
    {
        // do stuff
        return Ok();
    }
}

This also can be done in Visual Studio: Edit -> Paste Special -> Paste JSON as Classes

After how can I use RootObject in my function ?
