When ToInt32OrDefault encounter NULL and "" values, there will be no exception, resulting in the default value not being set normally.

[att1008]

Here is what to include in your request to make sure we implement a solution as quickly as possible.

1. Description

The default ToInt32OrDefault is to use Convert.ToInt32 instead of int.Parse or int.TryParse. when string is a NULL value or "" value, Convert.ToInt32 does not have an exception but directly returns a 0, which causes the set default value to be unable to be used normally.

2. Exception

If you are seeing an exception, include the full exception details (message and stack trace).
