create json structure for in wcf(dynamic key for json)

Question

How to declare dynamic key using class?

{
"balls": {"a8bf081d-eaef-44db-ba25-97ed8c0b30ef": {"team": {"runs": 1,
          "extras": 0,
          "ball_count": 1,
          "wicket": 0
        }
      },
}}

Answer 1

Based on your last Json format, still not valid but close. You have the following class

public class Team
{
    public int runs { get; set; }
    public int extras { get; set; }
    public int ball_count { get; set; }
    public int wicket { get; set; }
}

Using a Dictionary<string, Team> you can simply:

var objFoo = new
{
    balls = new Dictionary<string, Team>
    {
        {
            "a8bf081d-eaef-44db-ba25-97ed8c0b30ef",
            new Team{
                runs=1,
                extras=0,
                ball_count=1,
                wicket=0
            }
        }
    }
};

var result = JsonConvert.SerializeObject(objFoo);
