今天記壓縮解壓縮的使用,是基於開源項目ICSharpCode.SharpZipLib.Zip的使用。
一、壓縮:
/// <summary> /// 壓縮 /// </summary> /// <param name="sourceDirectory"></param> /// <param name="targetZipName"></param> /// <param name="recurse"></param> /// <param name="filter"></param> /// <returns></returns> public static void CreateZip(string zipFileName, string sourceDirectory, bool recurse=true, string fileFilter="") { if (string.IsNullOrEmpty(sourceDirectory)) { throw new ArgumentNullException("SourceZipDirectory"); } if (string.IsNullOrEmpty(zipFileName)) { throw new ArgumentNullException("TargetZipName"); } if (!Directory.Exists(sourceDirectory)) { throw new DirectoryNotFoundException("SourceDirecotry"); } if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP") throw new ArgumentException("TargetZipName is not zip"); FastZip fastZip = new FastZip(); fastZip.CreateZip(zipFileName, sourceDirectory, recurse, fileFilter); }
二、解壓縮:
/// <summary> /// 解壓 /// </summary> /// <param name="zipFileName"></param> /// <param name="targetDirectory"></param> /// <param name="fileFilter"></param> public static void ExtractZip(string zipFileName, string targetDirectory, string fileFilter="") { if (string.IsNullOrEmpty(zipFileName)) { throw new ArgumentNullException("ZIPFileName"); } if (!File.Exists(zipFileName)) { throw new FileNotFoundException("zipFileName"); } if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP") { throw new ArgumentException("ZipFileName is not Zip "); } FastZip fastZip = new FastZip(); fastZip.ExtractZip(zipFileName, targetDirectory, fileFilter); }
三、添加文件至壓縮文件中
/// <summary> /// 添加文件到壓縮文件中 /// </summary> /// <param name="zipFileName"></param> /// <param name="filesNames"></param> public static void AddFileToZip(string zipFileName, List<string> filesNames) { if (string.IsNullOrEmpty(zipFileName)) { throw new ArgumentNullException("ZipName"); } if (!File.Exists(zipFileName)) { throw new FileNotFoundException("ZipName"); } if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP") { throw new ArgumentException("ZipFileName is not Zip "); } if(filesNames==null||filesNames.Count<1) return; using (ZipFile zFile = new ZipFile(zipFileName)) { zFile.BeginUpdate(); foreach (string fileName in filesNames) { zFile.Add(fileName); } zFile.CommitUpdate(); } }
四、移除壓縮文件中的文件
/// <summary> /// 移除壓縮文件中的文件 /// </summary> /// <param name="zipName"></param> /// <param name="fileNames"></param> public static void DeleteFileFromZip(string zipFileName, IList<string> fileNames) { if (string.IsNullOrEmpty(zipFileName)) { throw new ArgumentNullException("ZipName"); } if (Path.GetExtension(zipFileName).ToUpper() != ".ZIP") { throw new ArgumentException("ZipName"); } if(fileNames==null||fileNames.Count<1) { return ; } using (ZipFile zipFile = new ZipFile(zipFileName)) { zipFile.BeginUpdate(); foreach(string fileName in fileNames) { zipFile.Delete(fileName); } zipFile.CommitUpdate(); } }
以上是基於ICSharpCode.SharpZipLib.Zip的部分使用,當然還有許多地方需要學習的。ICSharpCode.SharpZipLib.Zip使用起來比較快速方便,不想GZip那樣對文件進行壓縮時,還要進行復雜的操作。
今天就寫這么多吧。
