Asp.Net[C#]在线压缩解压

从清清月儿那看到的，随便改了一下，以备以后使用。

1.增加一下引用

using System.IO;
using Microsoft.Win32;
using System.Diagnostics;

2.主要代码之压缩

/// <summary>
/// 压缩文件
/// </summary>
/// <param name="DFilePath">需要压缩的文件夹或者单个文件</param>
/// <param name="DRARName">生成压缩文件的文件名</param>
/// <param name="DRARPath">生成压缩文件保存路径</param>
/// <returns></returns>
protected bool RAR(string DFilePath, string DRARName,string DRARPath)
{
String the_rar;
RegistryKey the_Reg;
Object the_Obj;
String the_Info;
ProcessStartInfo the_StartInfo;
Process the_Process;
try
{
the_Reg = Registry.ClassesRoot.OpenSubKey(@"Applications/WinRAR.exe/Shell/Open/Command");
the_Obj = the_Reg.GetValue("");
the_rar = the_Obj.ToString();
the_Reg.Close();
the_rar = the_rar.Substring(1, the_rar.Length - 7);
the_Info = " a " + " " + DRARName + " " + DFilePath; //命令 + 压缩后文件名 + 被压缩的文件或者路径
the_StartInfo = new ProcessStartInfo();
the_StartInfo.FileName = the_rar;
the_StartInfo.Arguments = the_Info;
the_StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
the_StartInfo.WorkingDirectory = DRARPath ; //RaR文件的存放目录。
the_Process = new Process();
the_Process.StartInfo = the_StartInfo;
the_Process.Start();
return true;
}
catch (Exception ex)
{
return false;
}
}

3.主要代码之解压

/// <summary>
/// 解压缩到指定文件夹
/// </summary>
/// <param name="RARFilePath">压缩文件存在的目录 </param>
/// <param name="RARFileName">压缩文件名称 </param>
/// <param name="UnRARFilePath">解压到文件夹</param>
/// <returns></returns>
protected bool UnRAR(string RARFilePath,string RARFileName,string UnRARFilePath)
{
//解压缩
String the_rar;
RegistryKey the_Reg;
Object the_Obj;
String the_Info;
ProcessStartInfo the_StartInfo;
Process the_Process;
try
{
the_Reg = Registry.ClassesRoot.OpenSubKey(@"Applications/WinRar.exe/Shell/Open/Command");
the_Obj = the_Reg.GetValue("");
the_rar = the_Obj.ToString();
the_Reg.Close();
the_rar = the_rar.Substring(1, the_rar.Length - 7);
the_Info = @" X " + " " + RARFilePath + RARFileName + " " + UnRARFilePath;
the_StartInfo = new ProcessStartInfo();
the_StartInfo.FileName = the_rar;
the_StartInfo.Arguments = the_Info;
the_StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
the_Process = new Process();
the_Process.StartInfo = the_StartInfo;
the_Process.Start();
return true;
}
catch (Exception ex)
{
return false;
}

}

3.示例
string oFilePath = @"C:/1/";
string oRARFileName = "1.rar";
string oToFilePath = @"C:/2/";

//if (RAR(oFilePath, oRARFileName, oToFilePath))

if (UnRAR(oFilePath, oRARFileName, oToFilePath))
Response.Write("OK");
else
Response.Write("No");
