Answer 1

I think it's generally not considered a good idea to call Convert.ToInt32 for the value reading out of database, what about the value is null, what about the value cannot be parsed. Do you have any exception handling code here.

1. Make sure the value is not null.
2. Check the value can be parsed before call Int32.Parse. Consider Int32.TryParse.
3. consider use a nullable type like int? in this case.

HTH.
