如何使用Windows Service监视文件大小? [英] How to monitor file size using windows service?

问题描述

我想构建一个Windows服务，以便它监视目录中的文件大小并在大小达到特定限制的任何地方弹出一条消息.我是C#的新手，所以我不确定如何开始.我在网上四处探索，但都没有显示如何监视文件大小.

I want to construct a windows service whereby it monitor the file size in a directory and pop up a message wherever the size reaches a certain limit. I''m quite new with c# so I''m not sure how to start. I explore little bit here and there on the net but none of it shows on how to monitor file size. Any kind of help would really be appreciated.

This approach allows for push technology approach, please see:

The pull technology is always bad, ineffective, it would imply periodic polling. Nothing happens to the file system, but you would still poll in vain. Something happens, but you are not responsive, because you use some polling period…
