Unfortunately, the SqlDataReader class isn t inheritable; it can t be subclassed directly. Instead, it is wrapped using containment and delegation. The result is that your data access code works the same as always, except that you never need to write checks for Null values. If a Null value shows up, SafeDataReader will automatically convert it to an appropriate empty value. Obviously, if you do care about the difference between a Null and an empty value, you can just use a regular SqlDataReader to retrieve the data.
