Hi,
As far as I know, you can achieve it by using ICSharpCode.SharpZipLib.Zip.
This dll file can be available at: http://www.icsharpcode.net/OpenSource/SharpZipLib/Download.aspx You can choose the edition you need after download.
The below codes can zip a file int zip format.
using ICSharpCode.SharpZipLib.Zip;
using System.IO;
using System.Threading;
ZipOutputStream zos = null;
protected void Button1_Click(object sender, EventArgs e)
{
string[] PathCellction = new string[2];
PathCellction[0] = "E:\\folder1";
PathCellction[1] = "c:\\folder2"; // Don't use c:\\folder2\\ or c:/folder2.
StartZip(PathCellction, "filename");
}
protected void StartZip(string[] strPathCellection, 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);
addZipEntry(strPathCellection);
zos.Finish();
zos.Close();
Response.Clear();
Response.BinaryWrite(ms.ToArray());
Response.End();
}
protected void addZipEntry(string[] PathStrCellection)
{
for (int i = 0; i < PathStrCellection.Length; i++)
{
string strPath = PathStrCellection[i].ToString();
addZipEntry(strPath, strPath.LastIndexOf("\\") + 1);
}
}
protected void addZipEntry(string PathStr, int strBaseIndex)
{
DirectoryInfo di = new DirectoryInfo(PathStr);
foreach (DirectoryInfo item in di.GetDirectories())
{
addZipEntry(item.FullName, strBaseIndex);
}
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.Remove(0, strBaseIndex);
ZipEntry entry = new ZipEntry(strEntryName);
zos.PutNextEntry(entry);
zos.Write(buffer, 0, buffer.Length);
fs.Close();
}
}
In the above codes, you can zip two different folders.
Hope it helps.
