我在做项目的时候需要将文件进行压缩和解压缩，于是就从http://www.icsharpcode.net下载了关于压缩和解压缩的源码，但是下载下来后，面对这么多的代码，一时不知如何下手。只好耐下心来，慢慢的研究，总算找到了门路。针对自己的需要改写了文件压缩和解压缩的两个类，分别为ZipClass和UnZipClass。其中碰到了不少困难，就决定写出来压缩和解压的程序后，一定把源码贴出来共享，让首次接触压缩和解压缩的朋友可以少走些弯路。-When I was doing the project will need to compress and decompress files, so downloading from http://www.icsharpcode.net on the compression and decompression of the source code, but it downloaded, and faced with so many code, 1:00 do not know how start with. Had under-resistant heart, the slow research and finally found the avenues. In light of their need to be rewritten a file compression and decompression of the two classes, namely ZipClass and UnZipClass. Which encountered many difficulties, it was decided to write out compression and decompression process, some paste out of the source code sharing, so that the first contact with compression and decompression of friends can take some less roundabout.
