【摘录】Asp.net实现在线压缩与解压

首先加入命名空间

using Microsoft.Win32;
using System.Runtime.InteropServices;
using System.Diagnostics;

实现压缩方法：

//压缩
        String strRar;
        RegistryKey rkReg;
        Object obj;
        String strInfo;
        ProcessStartInfo psiInfo;
        Process pProcess;
        try
        {
            rkReg = Registry.ClassesRoot.OpenSubKey(@"Applications\WinRAR.exe\Shell\Open\Command");
            obj = rkReg.GetValue("");
            strRar = obj.ToString();
            rkReg.Close();
            strRar = strRar.Substring(1, strRar.Length - 7);
            strInfo = "a  -r  -ep1 test.rar " + lblTree.Text + @"rar/test1.txt " + lblTree.Text + @"rar";//这里为rar的压缩命令格式（也可以自行扩展）
            psiInfo = new ProcessStartInfo();
            psiInfo.FileName = strRar;
            psiInfo.Arguments = strInfo;
            psiInfo.WindowStyle = ProcessWindowStyle.Hidden;
            psiInfo.WorkingDirectory = lblTree.Text + "rar"; ;//获取或设置要启动的进程的初始目录。
            pProcess = new Process();
            pProcess.StartInfo = psiInfo;
            pProcess.Start();
            Response.Write("<font color=red>压缩成功</font>");
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }

实现解压方法：

//解压缩
        String strRar;
        RegistryKey rkReg;
        Object obj;
        String strInfo;
        ProcessStartInfo psiInfo;
        Process pProcess;
        try
        {
            rkReg = Registry.ClassesRoot.OpenSubKey(@"Applications\WinRar.exe\Shell\Open\Command");
            obj = rkReg.GetValue("");
            strRar = obj.ToString();
            rkReg.Close();
            strRar = strRar.Substring(1, strRar.Length - 7);
            strInfo = " X " + lblTree.Text + @"rar/test.rar " + " " + lblTree.Text + @"unRar";
            psiInfo = new ProcessStartInfo();
            psiInfo.FileName = strRar;
            psiInfo.Arguments = strInfo;
            psiInfo.WindowStyle = ProcessWindowStyle.Hidden;
            pProcess = new Process();
            pProcess.StartInfo = psiInfo;
            pProcess.Start();
            Response.Write("<font color=red>解压缩成功</font>");
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }
