asp.net用代码压缩服务器上文件夹或文件_[Asp.Net教程]

asp.net用代码压缩服务器上文件夹或文件_[Asp.Net教程]
实现过程

1）先引用 ICSharpCode.SharpZipLib.dll；

2）.cs文件引入

using System.IO;
using System.Text;

using ICSharpCode.SharpZipLib.Checksums;
using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.GZip;

3）代码

#region 下列代码为压缩并下载代码
ZipOutputStream zos = null;
String strBaseDir = "";

void dlZipDir(string strPath, string strFileName)
{
MemoryStream ms = null;
Response.ContentType = "application/octet-stream";
strFileName = HttpUtility.UrlEncode(strFileName).Replace(’+’, ’ ’);
Response.AddHeader("Content-Disposition", "attachment; filename=" + strFileName + ".zip");
ms = new MemoryStream();
zos = new ZipOutputStream(ms);
strBaseDir = strPath + "\\";
addZipEntry(strBaseDir);
zos.Finish();
zos.Close();
Response.Clear();
Response.BinaryWrite(ms.ToArray());
Response.End();
}

void addZipEntry(string PathStr)
{
DirectoryInfo di = new DirectoryInfo(PathStr);
foreach (DirectoryInfo item in di.GetDirectories())
{
addZipEntry(item.FullName);
}
foreach (FileInfo item in di.GetFiles())
{
FileStream fs = File.OpenRead(item.FullName);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
string strEntryName = item.FullName.Replace(strBaseDir, "");
ZipEntry entry = new ZipEntry(strEntryName);
zos.PutNextEntry(entry);
zos.Write(buffer, 0, buffer.Length);
fs.Close();
}
}

PRotected void Button2_Click(object sender, EventArgs e)
{
string userPath ="D:\\华海实训（hohisoft.com）各级账号和密码";

dlZipDir(userPath, "华海实训（hohisoft.com）服务账号");
}

#endregion
