I\'m trying to create a JSON string representing a row from a database table to return in an HTTP res

Answer 1

I made the following method where it converts any DataReader to JSON, but only for single depth serialization:

you should pass the reader, and the column names as a string array, for example:

String [] columns = {"CustomerID", "CustomerName", "CustomerDOB"};

then call the method

public static String json_encode(IDataReader reader, String[] columns)
    {
        int length = columns.Length;

        String res = "{";

        while (reader.Read())
        {
            res += "{";

            for (int i = 0; i < length; i++)
            {
                res += "\"" + columns[i] + "\":\"" + reader[columns[i]].ToString() + "\"";

                if (i < length - 1)
                    res += ",";
            }

            res += "}";
        }

        res += "}";

        return res;
    }
