Answer 1

I got the answer

     public class BouncesAndBlocks
{
    public string status { get; set; }
    public string created { get; set; }
    public string email { get; set; }
    public string reason { get; set; }
}
     protected void btnBounces_Click(object sender, EventArgs e)
{
    string url = "https://api.sendgrid.com/api/bounces.get.json";
    string JS = GetResult(url);
    List<BouncesAndBlocks> res = (List<BouncesAndBlocks>)JsonConvert.DeserializeObject(JS, typeof(List<BouncesAndBlocks>));
    foreach (var item in res)
    {
        //Store in database
        lbl.Text = "Date:" + item.created.ToString() + "    Status:" + item.status.ToString() + "     Email:" + item.email.ToString() + "       Message:" + item.reason.ToString() + "";

    }
}

To read a JSON string in .NET, I recommend using Newtonsoft Json.NET.

Here is a simple example of deserializing a string into an object and reading a property:

string json = @"{
  'Name': 'Bad Boys',
  'ReleaseDate': '1995-4-7T00:00:00',
  'Genres': [
    'Action',
    'Comedy'
  ]
}";

Movie m = JsonConvert.DeserializeObject<Movie>(json);

string name = m.Name;
// Bad Boys

Note that you will have to define the object that you want to deserialize the values into ahead of time; you can see that in this example there is a Type Movie that already exists, and the JsonConverter matches the properties in the JSON string to the properties of that type.

If you do not want to create a Movie class, you can use System.Web.Script.Serialization to parse and get a dynamic object.

JavaScriptSerializer js = new JavaScriptSerializer();
dynamic movie = js.Deserialize<dynamic>(json);
