Ionic.Zip

1.Ionic.zIP 实现文件压缩和解压

2.压缩：

/// <summary>
        /// 压缩文件
        /// </summary>
        /// <param name="zipdirectory">压缩文件目录</param>
        /// <param name="zipfileName">压缩文件名称</param>
        /// <param name="adddirectoryfile">需要添加到压缩文件的目录 物理路径</param>
        /// <param name="addfiles">需要添加到压缩文件的文件  物理路径</param>
        /// <returns>是否成功</returns>
        /// <example>
        /// CompZipFiles(@"E:\\zipfile",DateTime.Now.ToString("yyMMddHHmmssff") + ".zip",@"E:\\testzip",new string[]{@"E:\\crebas.sql"}}
        /// CompZipFiles(@"E:\\zipfile",DateTime.Now.ToString("yyMMddHHmmssff") + ".zip",@"E:\\testzip",null}
        /// </example>
        public bool CompZipFiles(string zipdirectory, string zipfileName, string adddirectoryfile, string[] addfiles)
        {
            bool result = false;//是否成功
            try
            {
                if (!Directory.Exists(zipdirectory)) Directory.CreateDirectory(zipdirectory);
                using (ZipFile zip = new ZipFile(zipdirectory + "\\" + zipfileName, Encoding.Default))
                {
                    zip.Password = "lin.su";//加密压缩
                    if (!string.IsNullOrEmpty(adddirectoryfile)) zip.AddDirectory(adddirectoryfile);//添加目录到zip中
                    if (addfiles!=null && addfiles.Length > 0)
                    {
                        for (int i = 0; i < addfiles.Length; i++)
                        {
                            zip.AddFile(addfiles[i]);//添加文件到zip中
                        }
                    }
                    zip.Save();
                    result = true;
                }
            }
            catch (Exception)
            {
                throw;
                
            }
            return result;
        }

3.解压：

/// <summary>
        /// 解压文件
        /// </summary>
        /// <param name="zipdirectory">zip 文件目录</param>
        /// <param name="zipfileName">zip文件名称</param>
        /// <param name="dedirectoryfile">解压目标文件目录</param>
        /// <param name="defiles">解压的文件名称</param>
        /// <param name="isAll">是否全部解压</param>
        /// <returns>是否成功</returns>
        /// <example>
        /// ExtractZipFiles(@"E:\\zipfile", "13120210435607.zip", @"E:\\testzip2", new string[]{@"E:\\crebas.sql"}, false);
        /// ExtractZipFiles(@"E:\\zipfile", "13120210435607.zip", @"E:\\testzip2", null, true);
        /// </example>
        public bool ExtractZipFiles(string zipdirectory, string zipfileName, string extractdirectoryfile, string[] extractfiles, bool isAll)
        {
            bool result = false;//是否成功
            try
            {
                if (!Directory.Exists(extractdirectoryfile)) Directory.CreateDirectory(extractdirectoryfile);
                using (ZipFile zip = ZipFile.Read(zipdirectory + "\\" + zipfileName ))
                {
                    zip.Password = "lin.su";//密码解压
                    //Extract解压zip文件包的方法
                    if (isAll)
                    {
                        foreach (ZipEntry entry in zip)
                        {
                            //Extract解压zip文件包的方法，参数是保存解压后文件的路基
                            entry.Extract(extractdirectoryfile);
                        }  
                    }
                    else
                    {
                        if(extractfiles!=null && extractfiles.Length>0){
                            for (int i = 0; i < extractfiles.Length; i++)
                            {
                                zip[extractfiles[i]].Extract(extractdirectoryfile);
                            }
                        }
                    }
                    result = true;
                }
            }
            catch (Exception)
            {
                throw;

}
            return result;
        }

备注：解压出来的文件名如果有中文，则会出现乱码（是程序自动解压会有乱码）如果是手动解压就没有问题，不知道什么原因，估计有要修改源代码，如果谁弄好告诉我了
