C# ZIP压缩工具小程序实现 支持多个文件和文件夹

主要用到了一个SharpLibZip.dll库

1、内部算法--支持多个文件和文件夹

using System; using System.Collections.Generic; using System.Text; using System.IO; using ICSharpCode.SharpZipLib; using ICSharpCode.SharpZipLib.Zip; using ICSharpCode.SharpZipLib.Checksums; namespace ZipUnZipLib{

// <summary> /// 压缩类 /// </summary> public class ZipClass { /// <summary> /// 递归压缩文件夹方法 /// </summary> /// <param name="FolderToZip"></param> /// <param name="s"></param> /// <param name="ParentFolderName"></param> privatebool ZipFileDictory(string FolderToZip, ZipOutputStream s, string ParentFolderName) { bool res = true; string[] folders, filenames; ZipEntry entry = null; FileStream fs = null; Crc32 crc = new Crc32(); try{ //创建当前文件夹 entry = new ZipEntry(Path.Combine(ParentFolderName, Path.GetFileName(FolderToZip) + "/")); //加上 “/” 才会当成是文件夹创建 s.PutNextEntry(entry); s.Flush(); //先压缩文件，再递归压缩文件夹
