MySqlDataReader.Read() throws ArgumentOutOfRangeException - mysql

Question

I'm working with mysql .net connector 6.4.4 at win7 x64 platform. While reading data from MySqlDataReader Object, it throws exception after 18th row. But in another application I could take 40 rows without errors.
The error is just here:
MySqlDataReader.Read()
Any helps would be very appreciated.
Exception details:
System.ArgumentOutOfRangeException was unhandled
Message=Non-negative number required.

Updated:
I fixed this problem by setting target platfrom from x86 to Any CPU. Now works properly.
