用c#.net隐藏文本文件 [英] hiding text file with c#.net

问题描述

我需要编写文本文件，并将该文本文件的属性设置为"System"，"ReadOnly"，"Archive"，"Hide".

您可以通过右键单击文件，然后选中/取消选中文件的属性来进行操作.

我如何使用C#做到这一点.

As you can do by right clicking on the file and check/uncheck the attributes of file.

How I can do this using C#.

推荐答案

为此使用FileAttribute

Use the FileAttribute for this

File.SetAttributes("pathToFile",FileAttributes.Hidden)

这些操作完全是幼稚的.您可以隐藏文件或目录，任何其他代码都可以显示它.它根本不提供任何保护.实际上，几乎所有文件管理器都为您提供查看所有文件的选项.例如，即使是只读文件，也仅在发出一条警告后便被删除.这样，使用属性进行操作就毫无意义.您可以认为文件系统功能的这一部分几乎"已过时.

除非您使用权限，否则您将对此无能为力.您可以从这里开始:

These manipulations are totally naive. You can hide the file or directory, any other code can show it. It does not provide any protection at all. In fact nearly all File Managers routinely provide you with the option to see all the files. Even read-only files are, say, deleted, after just one warning. In this way, manipulations with attributes simply make no sense. You can consider this part of file system functionality "almost" obsolete.

You can do nothing about this unless you use permissions. You can start from here:

However, I would advice not doing it. Messing up with permission and hide anything, taking the risk to leave hidden files forever due to different mistakes? Looks childish. Consider 1) doing everything on an open way, which might be your best choice; 2) using encryption (which is much stronger and more robust then any system tricks taken together, 3) using resources embedded in an executable; 4) using isolated storage if applicable.

On isolated storage, please see:
