推荐答案

不要在快速答案下发布 - 如果您从文章中获得了代码，那么该文章底部的添加评论或问题按钮，会将电子邮件发送给作者。然后他们会被告知你希望与他们交谈。

在这里发布这个依赖于他们匆匆而过并意识到这是为了他们。

Don't post this under Quick Answers - if you got the code from an article, then there is a "Add a Comment or Question" button at the bottom of that article, which causes an email to be sent to the author. They are then alerted that you wish to speak to them.
Posting this here relies on them "dropping by" and realising it is for them.
