I know it’s not the direct answer to your question, but it’d be much simpler if you just used
ExecuteScalarto get your count value, since you only have one row/value being returned:Since Count will always return a number with your query in SQL Server (zero if no rows), then you don’t need all the extra checks required for using the reader.
