Creating a JSON array

Question

I am new to JSON. I am trying to create below JSON format using C#:

series: {
   name: "series1",
   data: [[0,2],[1,3],[2,1],[3,4]]
}

I am struggling with the data part. What should be my .NET code to achieve the above format?

How is the data stored in your C# code? What have you tried? — clcto

You can also use Json.NET to achieve this. It is a popular library for working with Json. — Daniel A.A. Pelsmaeker

List<int[]> arr = new List<int[]>()
    {
        new[]{0,2},new[]{1,3},new[]{2,1},new[]{3,4},
    };

var obj = new { data = arr };

string json = JsonConvert.SerializeObject(obj);

OUTPUT: {"data":[[0,2],[1,3],[2,1],[3,4]]}

OR

declare these classes (see http://json2csharp.com/)

public class RootObject
{
    public Series series { get; set; }
}

public class Series
{
    public string name { get; set; }
    public List<List<int>> data { get; set; }
}

create an instance of RootObject, fill the properties, and serialize it.

Use newtonsoft Json.net to serialize the objects, available via nuget or http://james.newtonking.com/json

Create the objects like this

var seriesContent = new Dictionary<string, object>
{
    {"name", "series1"},
    {"data", new[] {new[]{0,2},new[]{1,3},new[]{2,1},new[]{3,4}}}
};

var series = new Dictionary<string, object>
{
    {"series", seriesContent}
};

var s = JsonConvert.SerializeObject(series);

s will contain

{
    "series": {
        "name": "series1",
        "data": [
            [0, 2],
            [1, 3],
            [2, 1],
            [3, 4]
        ]
    }
}
