    for (int i=0;i < reader.FieldCount;i++)
    {
      string fieldType = reader.GetDataTypeName(i);
      string fieldName = reader.GetName(i);
      string fieldType2 = reader.GetFieldType(i).FullName;
      Console.WriteLine(fieldName+"\t"+ fieldType+"\t"+ fieldType2);
    }        
    reader.Close();
  }
