C#代码控制 zip rar 解压缩

首先 解压ZIP的方法:

#region 解压ZIP
        /// <summary>
        /// 解压ZIP
        /// </summary>
        /// <param name="zipFilePath">解压文件的物理地址</param>
        /// <param name="savePath">存放解压后的文件物理地址</param>
        /// <returns></returns>
        private static bool UnZipFile(string zipFilePath, string savePath, out string Message)
        {
            Message = "";
            bool result = true;
            try
            {
                using (ZipInputStream s = new ZipInputStream(File.OpenRead(zipFilePath)))
                {
                    ZipEntry theEntry;
                    while ((theEntry = s.GetNextEntry()) != null)
                    {
                        Console.WriteLine(theEntry.Name);
                        string directoryName = Path.GetDirectoryName(theEntry.Name);
                        string fileName = Path.GetFileName(theEntry.Name);
                        if (directoryName.Length > 0)
                        {
                            Directory.CreateDirectory(savePath + "/" + directoryName);
                        }
                        if (fileName != String.Empty)
                        {
                            using (FileStream streamWriter = File.Create(savePath + "/" + theEntry.Name))
                            {
                                int size = 2048;
                                byte[] data = new byte[2048];
                                while (true)
                                {
                                    size = s.Read(data, 0, data.Length);
                                    if (size > 0)
                                    {
                                        streamWriter.Write(data, 0, size);
                                    }
                                    else
                                    {
                                        break;
                                    }
                                }
                            }
                        }
                    }
                }
            }
            catch(Exception ex)
            {
                result = false;
                Message = ex.Message;
            }
            return result;
        }
        #endregion

然后就是解压rar的方法:

#region 解压RAR
        /// <summary>
        /// 解压RAR
        /// </summary>
        /// <param name="destPath">解压的文件名</param>
        /// <param name="savePath">解压的文件地址</param>
        /// <returns></returns>
        public bool UnRar(string fileRarName, string savePath, out string Message)
        {
            Message = "";
            bool result = false;
            ProcessStartInfo startinfo = new ProcessStartInfo(); ;
            Process process = new Process();
            string rarName = fileRarName; //将要解压缩的 .rar 文件名(包括后缀)  
            string path = savePath; //文件解压路径(绝对)  
            string rarPath = savePath;  //将要解压缩的 .rar 文件的存放目录(绝对路径)  
            string rarexe = "WinRAR.exe";  //WinRAR安装位置  

            try
            {
                //解压缩命令,相当于在要压缩文件(rarName)上点右键->WinRAR->解压到当前文件夹  
                string cmd = string.Format("x {0} {1} -y",
                                    rarName,
                                    path);
                startinfo.FileName = rarexe;
                startinfo.Arguments = cmd;                          //设置命令参数  
                startinfo.WindowStyle = ProcessWindowStyle.Hidden;  //隐藏 WinRAR 窗口  

                startinfo.WorkingDirectory = rarPath;
                process.StartInfo = startinfo;
                process.Start();
                process.WaitForExit(); //无限期等待进程 winrar.exe 退出  
                if (process.HasExited)
                {
                    result = true;
                }
            }
            catch (Exception ex)
            {
                result = false;
                Message = ex.Message;
                Framework.Core.Logging.LogManager.GetCurrentClassLogger().Fatal("在线阅读电子会刊异常:" + ex.ToString());
            }
            finally
            {
                process.Dispose();
                process.Close();
            }
            return result;
        }
        #endregion

然后就是一些文件夹之间的操作:

/// <summary>
        /// 删除所有文件(文件夹)包括本身
        /// </summary>
        /// <param name="dir"></param>
        public void DeleteFolderAll(string dir)
        {
            if (Directory.Exists(dir)) //如果存在这个文件夹删除之   
            {
                foreach (string d in Directory.GetFileSystemEntries(dir))
                {
                    if (File.Exists(d))
                        File.Delete(d); //直接删除其中的文件                          
                    else
                        DeleteFolderAll(d); //递归删除子文件夹   
                }
                Directory.Delete(dir, true); //删除已空文件夹                   
            }
        }  

        /// <summary>
        /// 删除某个路径下的所有东西
        /// </summary>
        /// <param name="dirPath"></param>
        public static void DeleteFolder(string dirPath)
        {
            if (Directory.Exists(dirPath))
            {
                foreach (string content in Directory.GetFileSystemEntries(dirPath))
                {
                    if (Directory.Exists(content))
                    {
                        Directory.Delete(content, true);
                    }
                    else if (File.Exists(content))
                    {
                        File.Delete(content);
                    }
                }
            }
        }  

好了,结束!
