Hi Friends,

I am new to WCF and have to make a service that returns the DataSet values in Json format.
I know the Json is a key:value format.
But,I could not understand if I have 10 rows in my dataset how can I return in the json format.

Does it work just to include [WebGet(ResponseFormat=WebMessageFormat.Json)] attribute to my operation contract, and return to my Dataset in return type of method.

    public interface IService1
        DataSet GetData(string prodID);
 public class Service1 : IService1
public DataSet GetData(string prodID)
     DataSet ds = new DataSet();
   //I am populating the dataset here
return ds;
//how should I make it in json format now.

Have a look at ( It's a library to serialize Objects into JSON. You can use it to convert DataSet to A JSON String and return it from your service method instead of DataSet.
