问题描述

如何在不使用第三方dll的情况下制作文件夹（目录）压缩（RAR）文件。

How to Make a folder(directory) compressed (RAR) file without using third party dlls.

推荐答案

Rar格式和算法是专有的。但您可以免费获得unrar代码（ http://www.rarlab.com/rar_add.htm [ ^ ]），所以你可能会抓紧机会获得一个想法。



为什么你坚持使用rar，还有其他格式，你可以不受限制地自己实现。

但是毕竟，为什么还要烦恼实现你已经拥有的东西？



只需注意：压缩算法非常复杂。在这里你可以阅读关于RLE之后最简单的内容：霍夫曼代码 [ ^ ]

Rar format and algorithm is proprietary. But you can have unrar code for free (http://www.rarlab.com/rar_add.htm[^]), so you might take you chance to get an idea.

Why do you stick to rar, there are other other formats, where you can make your own implementation without restriction.
But after all, why bothering with implementing something that you already have?

Just a note: compression algorithms are really complicated. Here you can read about the probably simplest after RLE: the Huffman code[^]

显然你需要遍历你目录中的所有文件使用GZipStream压缩这些文件..

Well obviously you need to iterate through all files in your directory and copress those files with GZipStream..
