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

Answer 1

My version:

This doesn't use DataSchema and also wraps the results in an array, instead of using a writer per row.

SqlDataReader rdr = cmd.ExecuteReader();

StringBuilder sb = new StringBuilder();
StringWriter sw = new StringWriter(sb);    

using (JsonWriter jsonWriter = new JsonTextWriter(sw)) 
{    
    jsonWriter.WriteStartArray();

    while (rdr.Read())
    {
        jsonWriter.WriteStartObject();

        int fields = rdr.FieldCount;

        for (int i = 0; i < fields; i++)
        { 
            jsonWriter.WritePropertyName(rdr.GetName(i));
            jsonWriter.WriteValue(rdr[i]);
        }

        jsonWriter.WriteEndObject();
    }

    jsonWriter.WriteEndArray();
}
