Deserialize JSON array of arrays into List of Tuples using Newtonsoft

Question

I am receiving data that looks like this from an online service provider:

{
  name: \"test data\",
  data: [
    [ \"2017-05-31\", 2388.33 ],
    [ \"2017-04         


        

Answer 1

So using JSON.NET LINQ, I managed to get it to work as you prescribed...

var result = JsonConvert.DeserializeObject(json);
var data = new TestData
{
    Name = (string)result["name"],
    Data = result["data"]
        .Select(t => new Tuple(DateTime.Parse((string)t[0]), (double)t[1]))
        .ToList()
};

This is the full test I wrote

public class TestData
{
    public string Name;
    public List> Data;
}

[TestMethod]
public void TestMethod1()
{
    var json =
    @"{
        name: ""test data"",
        data: [
        [ ""2017-05-31"", 2388.33 ],
        [ ""2017-04-30"", 2358.84 ],
        [ ""2017-03-31"", 2366.82 ],
        [ ""2017-02-28"", 2329.91 ]
        ],
    }";

    var result = JsonConvert.DeserializeObject(json);
    var data = new TestData
    {
        Name = (string)result["name"],
        Data = result["data"]
            .Select(t => new Tuple(DateTime.Parse((string)t[0]), (double)t[1]))
            .ToList()
    };

    Assert.AreEqual(2388.33, data.Data[0].Item2);
}

However, while this may work, I am in agreement with the rest of the comments/answers that using tuples for this is probably not the correct way to go. Using concrete POCO's is definitely going to be a hell of a lot more maintainable in the long run simply because of the Item1 and Item2 properties of the Tuple<,>.

They are not the most descriptive...
