I have some JSON output that looks like this:
{
"raw_data": [
[
1088553600000,
1.3635
],
[
1091232000000,
1.3538
] ]
}
How can I structure a class to deserialize this into since the values in raw_data do not have a 'key' name?

I ve also problem with no-key array. My solution:
/* Class */
public class Example
{
public Int32 count { get; set; }
public Boolean result { get; set; }
public String text { get; set; }
public DateTime date { get; set; }
public List<object[]> raw_data { get; set; }
public Example(Int32 count, Boolean result, String text, DateTime date, List<object[]> raw_data)
{
this.count = count;
this.result = result;
this.text = text;
this.date = date;
this.raw_data = raw_data;
}
}
/* Main */
[...]
using Newtonsoft.Json.Serialization;
using Newtonsoft.Json;
private void button_Click(object sender, EventArgs e)
{
/* Serialize Object */
List<object[]> raw = new List<object[]>();
raw.Add(new object[]{ 1088553600000, 1.3635M });
raw.Add(new object[]{ 1091232000000, 1.3538M });
Example em = new Example(5490, true, "Show me the way", DateTime.Now, raw);
String json = JsonConvert.SerializeObject(em);
richTextBox.Text = json;
/* Deserialize Object */
String json_to_deserialize = @"{
""raw_data"": [
[
1088553600000,
1.3635
],
[
1091232000000,
1.3538
] ]
}";
Example em1 = JsonConvert.DeserializeObject<Example>(json_to_deserialize);
richTextBox.Text = em1.raw_data.Count.ToString();
// or richTextBox.Text = em1.raw_data[0].First().ToString();
// or cast raw_data to whatever u want
}
greetings

i ve found a solution:
""raw_data"": [
[
1088553600000, <- `id` property in RawData class
1.3635 <- `point` property in RawData class
],
using System;
using System.Collections.Generic;
using Newtonsoft.Json.Linq;
using Newtonsoft.Json;
using System.Globalization;
namespace Test
{
public class Example
{
public Int32 count { get; set; }
public Boolean result { get; set; }
public String text { get; set; }
public DateTime date { get; set; }
public List<RawData> raw_data { get; set; }
public Example(Int32 count, Boolean result, String text, DateTime date, List<RawData> raw_data)
{
this.count = count;
this.result = result;
this.text = text;
this.date = date;
this.raw_data = raw_data;
}
public Example()
{
}
}
[JsonConverter(typeof(RawDataConverter))]
public class RawData
{
public Int64 id { get; set; }
public Double point { get; set; }
public RawData()
{
}
}
public class RawDataConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
if (objectType == typeof(RawData))
{
return true;
}
return false;
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
JArray ja = new JArray();
while (reader.Read())
{
if (reader.TokenType == JsonToken.EndArray) break;
ja.Add(reader.Value);
}
RawData rd = new RawData();
/* There probably will be "Input string in not correct format" exceptions*/
rd.id = Int64.Parse(ja[0].ToString());
rd.point = Double.Parse(ja[1].ToString(), new CultureInfo("en-US"));
/**/
return rd;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
