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

Rather than use tuples, I would create a class that is specific to the task. In this case your JSON data comes in as a list of lists of strings which is a bit awkward to deal with. One method would be to deserialise as List> and then convert afterwards. For example, I would go with 3 classes like this:

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

public class TestData
{
    public string Name;
    public IEnumerable Data;
}

public class TestDataItem
{
    public DateTime Date { get; set; }
    public double Value { get; set; }
}

Now deserialise like this:

var intermediate = JsonConvert.DeserializeObject(json);

var testData = new TestData
{
    Name = intermediate.Name,
    Data = intermediate.Data.Select(d => new TestDataItem
    {
        Date = DateTime.Parse(d[0]),
        Value = double.Parse(d[1])
    })

};
