步驟

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）代碼

#region 下列代碼為壓縮并下載代碼

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:華海實訓(xùn)（qqview.com）各級賬號和密碼";

dlZipDir(userPath, "華海實訓(xùn)（qqview.com）服務(wù)賬號");

}
