推荐答案

不要在问题与答案"下发布此内容-如果您从某篇文章中获得了代码，则该文章底部将出现一个新消息"按钮，这将导致向作者发送电子邮件.然后会通知他们您希望与他们交谈.
将其发布到此处依赖于他们的下落"，并意识到它们是针对他们的.

Don''t post this under Questions & Answers - if you got the code from an article, then there is a "new message" 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.

最好的方法是在每次需要图像时都重新创建图像.这样，它变得更加随机.您已经找到此CodeProject文章，建议您使用其中包含的代码.

CAPTCHA图片 [

The BEST way is to recreate the image every time it''s needed. This way, it becomes much more random. You''ve already found this CodeProject article, and I suggest you use the code contained therein.

CAPTCHA Image[^]

替换

this.Session["CaptchaImageText"] = GenerateRandomCode();

this.Session["CaptchaImageText"] = GenerateCodeFromDataBase();

然后在您的 GenerateCodeFromDataBase()方法内部编写代码，该代码将从所需的表中检索数据.

希望以上信息对您有所帮助.如果您还有其他顾虑，请告诉我.

And Inside your GenerateCodeFromDataBase() method write code that will retrieve data from your desired table.

I hope the above information will be helpful. If you have more concerns, please let me know.
