Description: There is a IndexOutOfBounds exception when reading BLOB columns with MySqlDataReader as strings with MySqlDataReader.GetString(index). Exception occures in MySqlBinary.ToString(). Method uses index and length variables to locate subset of a byte buffer. Other methods such as ToBytes() are ignoring these values and using whole buffer. How to repeat: see description Suggested fix: Use whole buffer for string conversion, since indexes are not valid. Replace line 57 in mysqlbinary.cs, containing statement: return encoding.GetString( (byte[])mValue, (int)index, (int)length ); with: return encoding.GetString((byte[])mValue);
