c#文件压缩/解压

压缩

private void skinButton1_Click(object sender, EventArgs e)        {            FilesUploadFor.ZipDirectory(foldertozip.Text,zipedfilename.Text);            filesUploadFor.DisplaylistboxMsg("压缩实现");        }

ZipDirectory

压缩用的是库函数

       /// <summary>       /// 压缩文件夹       /// </summary>       /// <param name="folderToZip">须要压缩的文件夹</param>       /// <param name="zipedFileName">压缩后的Zip残缺文件名</param>        public static void ZipDirectory(string folderToZip, string zipedFileName)        {            ZipDirectory(folderToZip, zipedFileName, string.Empty, true, string.Empty, string.Empty, true);        }         /// <summary>        /// 压缩文件夹        /// </summary>        /// <param name="folderToZip">须要压缩的文件夹</param>        /// <param name="zipedFileName">压缩后的Zip残缺文件名（如D:\test.zip）</param>        /// <param name="isRecurse">如果文件夹下有子文件夹，是否递归压缩</param>        /// <param name="password">解压时须要提供的明码</param>        /// <param name="fileRegexFilter">文件过滤正则表达式</param>        /// <param name="directoryRegexFilter">文件夹过滤正则表达式</param>        /// <param name="isCreateEmptyDirectories">是否压缩文件中的空文件夹</param>         public static void ZipDirectory(string folderToZip, string zipedFileName, string password, bool isRecurse, string fileRegexFilter, string directoryRegexFilter, bool isCreateEmptyDirectories)        {            FastZip fastZip = new FastZip();            fastZip.CreateEmptyDirectories = isCreateEmptyDirectories;            fastZip.Password = password;            fastZip.CreateZip(zipedFileName, folderToZip, isRecurse, fileRegexFilter, directoryRegexFilter);        }

解压缩

  private void skinButton2_Click(object sender, EventArgs e)        {            filesUploadFor.UnZip(zipedfilename.Text,"");             filesUploadFor.DisplaylistboxMsg("解压缩实现");        }

UnZip

解压用的是库函数
