这看起来可能是例外的地方.
要基于带数字索引的ItemArray进行编码是不好的，请将其放在一边.每当您使用它时，请确保您拥有该权利并且不为null.
Check for null before accessing the ItemArray''s data.
This looks like a possible place for the exception.
To code based on ItemArray indexed with numbers are not good, keeping that aside.. whenever you are using it, make sure you have that right and is not null.
Check for null before accessing the ItemArray''s data.
