双重否定是否必要

[DUWENINK]

what happened ? When I use this attribute, I feel that my brain has received a fatal blow

I hope the usage of double negation can be removed In order to solve this problem, I can only deal with it this way to protect my brain

考虑将IEIgnoreAttribute这个特性再拆解成2个特性：

• IEImportIgnoreAttribute
• IEExportIgnoreAttribute

然后IEIgnoreAttribute继承这两个特性。
