10 楼谢谢！但是我只需要 WinRar 的才符合我需要的，用其他的不好。

在二楼的代码基础上进行了更改，剔除了代码的一些错误和看不明白的代码，更改如下



using System;

using System.Collections.Generic;

using System.Text;

using System.Diagnostics;

using System.IO;



namespace Geoway.HJDMS.Service.Util

{



    public class Decompression

    {



        private string _winrarPath;

        private int _exitNum;

        public Decompression(string winrarPath)

        {

            _winrarPath = winrarPath;

        }

        private void KillWinRar()

        {

            Process[] processes = Process.GetProcesses();

            foreach (Process process in processes)

            {

                if (process.ProcessName == "WinRAR")

                {

                    process.Kill();

                }

            }

        }

        public bool Compress(string targetFileFullName, string destFolderPath)

        {

            bool Result = false;

            try

            {

                string cmd = string.Format( "A {0} {1} -r   ", destFolderPath,targetFileFullName );

                ProcessStartInfo startInfo = new ProcessStartInfo();

                startInfo.FileName = _winrarPath;

                startInfo.Arguments = cmd;

                startInfo.WindowStyle = ProcessWindowStyle.Hidden;

                startInfo.WorkingDirectory = Path.GetDirectoryName(targetFileFullName);

                Process process = new Process();

                process.StartInfo = startInfo;

                process.Start();

                process.WaitForExit();

                _exitNum = process.ExitCode;

                if (_exitNum == 0)

                {

                    Result = true;

                }

                process.Close();

                KillWinRar();

            }

            catch

            {

                return Result;

            }

            return Result;

        }

 

    }

}

经过测试，是可以运行。

使用的时候，只需要建立新类（Decompression），就可以使用。

使用Process.Run方法
下面是怎么使用命令行进行压缩的

命令行语法
--------------------------------------------------------------------------------

从命令行也可以运行 WinRAR 命令，常规的命令行语法描述如下:

WinRAR <命令> -<开关1> -<开关N> <压缩文件 > <文件...> <@列表文件...> <解压路径\>

命令要 WinRAR 运行的字符组合代表功能
开关切换操作指定类型，压缩强度，压缩文件类型，等等的定义。
压缩文件要处理的压缩文件名。
文件要处理的文件名。
列表文件列表文件是包含要处理文件名称的纯文本。文件名应该在第一卷启动。可以在列表文件中使用 //字符后添加注释。例如，你可以包含两列字符串创建 backup.lst:
c:\work\doc\*.txt //备份文本文档 c:\work\image\*.bmp //备份图片

c:\work\misc

并接着运行:

winrar a backup @backup.lst

你可以在命令行中同时指定普通的文件名和列表文件名。

解压路径只与命令 e 和 x ，搭配使用。指出解压文件添加的位置。如果文件夹不存在时，会自动创建。
