【摘錄】Asp.net實現在線壓縮與解壓

首先加入命名空間

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

實現壓縮方法：

{
function anonymous()
{
function anonymous()
{
function onclick()
{
this.style.display='none'; document.getElementById('Code_Closed_Text_180905').style.display='none'; document.getElementById('Code_Open_Image_180905').style.display='inline'; document.getElementById('Code_Open_Text_180905').style.display='inline';
}
}
}
}" style="display: none;" id="Code_Closed_Image_180905">{
function anonymous()
{
function anonymous()
{
function onclick()
{
this.style.display='none'; document.getElementById('Code_Open_Text_180905').style.display='none'; getElementById('Code_Closed_Image_180905').style.display='inline'; getElementById('Code_Closed_Text_180905').style.display='inline';
}
}
}
}" id="Code_Open_Image_180905">
//壓縮
        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";//這裡為rar的壓縮命令格式（也可以自行擴充）
            psiInfo = new ProcessStartInfo();
            psiInfo.FileName = strRar;
            psiInfo.Arguments = strInfo;
            psiInfo.WindowStyle = ProcessWindowStyle.Hidden;
            psiInfo.WorkingDirectory = lblTree.Text + "rar"; ;//擷取或設定要啟動的進程的初始目錄。
            pProcess = new Process();
            pProcess.StartInfo = psiInfo;
            pProcess.Start();
            Response.Write("<font color=red>壓縮成功</font>");
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }

實現解壓方法：

//解壓縮
        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>解壓縮成功</font>");
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }
