SharpZipLib压缩文件夹及文件

对于之前发布的有关Net中使用压缩解压缩技术中，有个相当大的缺陷，是压缩文件时，不能递归压缩子文件夹。现将递归压缩的方法提供一下，还望大家多多探讨。（该代码参考别人写的例子修改了一下） 注意：请引用以下类库 using System; using System.Collections.Generic; using System.Text; using System.IO; using System.DirectoryServices; using ICSharpCode.SharpZipLib.Zip; using ICSharpCode.SharpZipLib.GZip; using ICSharpCode.SharpZipLib.Checksums; public class ZipHelper { ......... #region 压缩文件夹,支持递归 ///

///　压缩文件夹 ///

/// 待压缩的文件夹 /// 压缩后文件路径（包括文件名） /// 是否递归压缩 /// public static bool Compress(string dir, string targetFileName,bool recursive) { //如果已经存在目标文件，询问用户是否覆盖 if (File.Exists(targetFileName)) { if (!_ProcessOverwrite(targetFileName)) return false; } if (recursive == false) return Compress(dir, targetFileName); FileStream ZipFile; ZipOutputStream ZipStream; //open ZipFile = File.Create(targetFileName); ZipStream = new ZipOutputStream(ZipFile); if (dir != String.Empty) { _CompressFolder(dir, ZipStream, dir); } //close ZipStream.Finish(); ZipStream.Close(); if (File.Exists(targetFileName)) return true; else return false; } ///
