转自园友:jimcsharp的博文C#实现Zip压缩解压实例【转】
在此基础上,对其中的压缩文件夹方法略作修正,并增加是否对父文件夹进行压缩的方法。(因为笔者有只压缩文件夹下的所有文件,却不想将选中的文件夹打入压缩文件的需求),话不多说,上代码:
其中需要依赖ICSharpCode.SharpZipLib.dll:
之后,新建一个类,代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using ICSharpCode.SharpZipLib;
using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.Checksums; namespace Zip.Util

压缩文件夹,是否包含父文件夹,调用:
public static bool ZipDirectory(string folderToZip, string zipedFile, Boolean IncludeParent) 解压缩功能我也将原方法注释了,重新找了一个方法,因为原方法在将.xml文件解压出来的时候,会在末尾加入一堆NULNULNULNUL.......,大家可以自己去尝试下。
2017.8.12补充:
解压自己的打包的压缩包报错:EOF in header.......
准备换winrar.
