推荐答案

这里很少有人有GIS工具的经验，所以您可能会发现很少的兴趣.我建议检查ESRI网站，因为他们一直在为想要与其产品接口的程序员提供API包.他们还有一个庞大的用户社区，您可能会在这里找到更多帮助.

我在工作中使用ArcInfo，但还没有时间研究shapefile的文件格式.您可能可以在ESRI网站上找到该信息.祝您好运！

Few people here have experience with GIS tools, so you may find little interest. I suggest checking the ESRI website, as they have been offering an API package for programmers who want to interface with their products. They also have a large user community where you might find more assistance.

I use ArcInfo at work, but haven''t had the time to research the file format for shapefiles; you probably can find that information at the ESRI site. Good luck!

-最简单的方法是，您希望将文件读入具有-(

-Well at the simplest level your going to want to read in the file to a "shapefile" class with class structure based on -(readthis^)
that will give you the class structure.

read/write in using Streams (Reader/Writer) it''s a little putzy..

then you simply add in the point you want at the appropriate place, adjust/update your other class variables (min-max etc.)

-it''s more coding but you will probably also want to make a ShapeContent base class and implement extensions for each shape content.

If your trying to draw a shape file.. that is altogether another layer on top of this.

我真的建议您为自己准备一些有关这些主题的书，或者至少找到一些网页致力于这项任务.您已经反复提出了类似的问题，看似很低级的任务，这显示出对该主题的基本知识匮乏.代码项目的目的是提供帮助，而不是为您工作.

与过去一样，我建议您对要达到的目标进行一些研究，编写一些代码，然后回来，并在遇到某些特定问题时问一个问题.别忘了发布您的代码，否则您似乎什么都没做.

I really suggest you get yourself some books on these topics, or at least find some web pages dedicated to this task. You have repeatedly asked similar questions, for apparently low-level tasks, which shows a basic lack of knowledge on the subject. The purpose of the Code Project is to provide help, not to do you work for you.

I suggest, as I have in the past, that you do some research on whatever it is you are trying to achieve, write some code then come back and ask a question when you are stuck on something specific. Don''t forget to post your code, or it looks like you haven''t done anything.
