1、在CharpDevlop上有个压缩的DLL,是免费开源的叫SharpZipLib。
下载之后解压用其net-20里面的DLL。
2.这里是网上收集的一个通用类
public class ZipHelper { /// <summary> /// 压缩文件 /// </summary> /// <param name="sourceFilePath"></param> /// <param name="destinationZipFilePath"></param> public static void CreateZip(string sourceFilePath, string destinationZipFilePath) { if (sourceFilePath[sourceFilePath.Length - 1] != System.IO.Path.DirectorySeparatorChar) sourceFilePath += System.IO.Path.DirectorySeparatorChar; ZipOutputStream zipStream = new ZipOutputStream(File.Create(destinationZipFilePath)); zipStream.SetLevel(6); // 压缩级别 0-9 CreateZipFiles(sourceFilePath, zipStream, sourceFilePath); zipStream.Finish(); zipStream.Close(); } /// <summary> /// 递归压缩文件 /// </summary> /// <param name="sourceFilePath">待压缩的文件或文件夹路径</param> /// <param name="zipStream">打包结果的zip文件路径(类似 D:\WorkSpace\a.zip),全路径包括文件名和.zip扩展名</param> /// <param name="staticFile"></param> private static void CreateZipFiles(string sourceFilePath, ZipOutputStream zipStream, string staticFile) { Crc32 crc = new Crc32(); string[] filesArray = Directory.GetFileSystemEntries(sourceFilePath); foreach (string file in filesArray) { if (Directory.Exists(file)) //如果当前是文件夹,递归 { CreateZipFiles(file, zipStream, staticFile); } else //如果是文件,开始压缩 { FileStream fileStream = File.OpenRead(file); byte[] buffer = new byte[fileStream.Length]; fileStream.Read(buffer, 0, buffer.Length); string tempFile = file.Substring(staticFile.LastIndexOf("\\") + 1); ZipEntry entry = new ZipEntry(tempFile); entry.DateTime = DateTime.Now; entry.Size = fileStream.Length; fileStream.Close(); crc.Reset(); crc.Update(buffer); entry.Crc = crc.Value; zipStream.PutNextEntry(entry); zipStream.Write(buffer, 0, buffer.Length); } } } }
3、调用方式
ZipHelper.CreateZip(pathFile,@"d:\test.zip");
