基于ICSharpCode.SharpZipLib.Zip的压缩解压缩

今天记压缩解压缩的使用，是基于开源项目ICSharpCode.SharpZipLib.Zip的使用。

一、压缩：

/// <summary>

        /// 压缩

        /// </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、解压缩：

/// <summary>

        /// 解压

        /// </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、添加文件至压缩文件中

 /// <summary>

        /// 添加文件到压缩文件中

        /// </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、移除压缩文件中的文件

     /// <summary>

        /// 移除压缩文件中的文件

        /// </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();

            }

        }

 

 

以上是基于ICSharpCode.SharpZipLib.Zip的部分使用，当然还有许多地方需要学习的。ICSharpCode.SharpZipLib.Zip使用起来比较快速方便，不想GZip那样对文件进行压缩时，还要进行复杂的操作。

今天就写这么多吧。
