asp.net在windows平台实现WinRAR压缩与解压的实现方法

时间:2022-06-25 08:23:30 编辑:袖梨 来源:一聚教程网

先来看WinRAR自身的支持调用命令:

压缩命令:a {0} {1} -r 【{0}:压缩后文件名|{1}:待压缩的文件物理路径】

ex:"a 你妹.rar f:MM -r" (含义为将f盘下MM的文件夹压缩为"你妹.rar"文件)

解压命令:x {0} {1} -y 【{0}:待解压文件名称|{1}:待解压文件物理路径】

ex:"x 幺妹.rar f:幺妹 -y"(待压缩文件物理路径:"f:幺妹幺妹.rar")

参数说明

参数

含义a

添加文件到压缩包x

以完整路径从压缩包解开压缩

c#调用通用类

 代码如下 复制代码

    public bool RAR(string path, string rarPath, string rarName)
    {
        bool flag = false;

            //压缩命令,相当于在要压缩的文件夹(path)上点右键->WinRAR->添加到压缩文件->输入压缩文件名(rarName)
            cmd = string.Format("a {0} {1} -r",
                                rarName,
                                path);
            startinfo = new ProcessStartInfo();
            startinfo.FileName = rarexe;

            }
            process.Close();

        }
        return flag;

    ///

    public bool UnRAR(string path, string rarPath, string rarName)

            rarexe = regvalue.ToString();
            regkey.Close();
            rarexe = rarexe.Substring(1, rarexe.Length - 7);

            Directory.CreateDirectory(path);
            //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
            cmd = string.Format("x {0} {1} -y",
                                rarName,
                                path);

        }
        catch (Exception e)
        {
            throw e;
        }
        return flag;
    }
}

调用方法

 代码如下 复制代码

WinRARCSharp win = new WinRARCSharp();

win.RAR("F:aaa", "f:", "a.rar"); // 压缩(将“f:aaa”目录文件压缩到“f:a.rar”)

win.UnRAR("f:呦M.zip", "f:MM", "GG"); // 解压(将“f:呦M.zip”解压到“f:MMGG”目录下)
