If you want to manipulate the zip features like create,extract and update zip files in .Net. You can implement from the third party libraries DotNetZip . You need to reference the dll ionic zip in your project and import namespace Ionic.Zip in the page.
In this example, I am adding the images and creating a zip file with the folder name called Album.
protected void btnDownload_Click(object sender, EventArgs e)
{
Response.Clear();
Response.ContentType = "application/zip";
Response.AddHeader("content-disposition", "filename=" + "Donload.zip");
using (ZipFile zip = new ZipFile())
{
foreach (ListItem item in chkAlbum.Items)
{
if (item.Selected)
{
zip.AddFile(item.Value, "Album");
}
}
zip.Save(Response.OutputStream);
}
}
Zip files Downloaded in browser specified path
