使用C＃进行文件压缩 [英] Files Compression using C#

问题描述

我使用此代码进行压缩，

i used this code for compression,

string fileToBeCompressed="E:\\access.accdb";
            string t = DateTime.Now.Day + "-" + DateTime.Now.Month + "-" + DateTime.Now.Year;
            string zipFilename = "E:\\"+t+".zip";
            FileStream target = new FileStream(zipFilename, FileMode.Create, FileAccess.Write);
            GZipStream alg = new GZipStream(target, CompressionMode.Compress);
            byte[] data = File.ReadAllBytes(fileToBeCompressed);
            alg.Write(data, 0, data.Length);
            alg.Flush();
            target.Close();

运行此代码后，我检查了E驱动器并找到了文件t.zip 。

但是当我想在这里制作Extract时，CRC文件中会出现错误信息

如何解决这个问题。

After run this code, i checked the E drive and found the file t.zip.
but when i want to make Extract here ,there is error message come in CRC for that file
how can i solve this problem .

推荐答案

GZipStream不压缩成ZIP格式 - 而是保存到GZip。这可以使用Winzip打开，但只有在您更改文件扩展名时：尝试

GZipStream does not compress into ZIP format- it saves to GZip instead. This is openable using Winzip, but only if you change the file extension: try

string zipFilename = "E:\\"+t+".accdb.gz";

而不是。

（您还需要文件扩展名，否则它不能很好地解压缩）

instead.
(You need the file extension as well, or it doesn't decompress so well)
