【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());
}
