推荐答案
你不能在他们的机器上执行此操作，因为大多数人根本不会安装iTextSharp库，只需使用UTC time，或使用他们的语言环境动态生成时间戳。
在大多数情况下，我建议使用HTML电子邮件，Outlook会尽最大努力确保进行更改以显示当前语言环境中的内容&mdash ;只要他们也使用Outlook;尽管如此，大多数当前的电子邮件提供商都提供此服务来查找和提取日历等的日期时间值。但是，需要修改PDF以更改该段落或块的值，这将需要您（r用户）有一个图书馆......等等。唯一的逻辑解决方案是在生成PDF之前实际使用它们的语言环境。
您可以要求用户输入他们的语言环境，或者发送UTC时间的电子邮件。用户将知道他们的日程安排的时间。
You cannot do that on their machine, as most of them won't have the iTextSharp library installed at all, to do so, just use "UTC time", or use their locales to generate the time stamp dynamically.
In most cases, I would recommend using an HTML email, Outlook will do maximum of its own to make sure that changes are made to show the content in current locale — provided they are also using Outlook; nonetheless, most of the current email providers provide this service to find out and extract date time values for calendars etc. However, PDF would require to be modified to change the value of that paragraph or chunk, which would then require you(r user) to have a library... So on and so forth. The only "logical" solution to this is to actually use their locales, before generating the PDFs.
You can ask the users to enter their locales, or send the emails with UTC time. Users will know what time it will be on their schedule.
