To create a SqlDataReader, you must call the ExecuteReader method of the SqlCommand object, instead of directly using a constructor. While the SqlDataReader is being used, the associated SqlConnection is busy serving the SqlDataReader, and no other operations can be performed on the SqlConnection other than closing it.
