Hi,
I am developing a website. I have a folder containing some images. Please somebody help me with the code so that the users can download the folder when they click on the download button.

Hi,
Thanks for your help. But i got a problem. The code works well with a single image(picture.bmp) in C drive. But i have a folder containing 6 pictures and the image folder is uploaded in the webserver. I need the code for downloading that folder when the online users click on the download album button.

Hi Bincy,
I'm not an expert in Web Apps but I'm pretty sure, folders are not downloadable. You should first add it to a zip file and then download the zip. This should allow the user to download all your images.
Hope that helped :-)!

I think you are absolutely correct here. Zipping the folder would solve your problem.

Try this example:
public void TheDownload(string path)
{
System.IO.FileInfo toDownload = new System.IO.FileInfo(HttpContext.Current.Server.MapPath(path));
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AddHeader("Content-Disposition",
"attachment; filename=" + toDownload.Name);
HttpContext.Current.Response.AddHeader("Content-Length",
toDownload.Length.ToString());
HttpContext.Current.Response.ContentType = "application/octet-stream";
HttpContext.Current.Response.WriteFile(patch);
HttpContext.Current.Response.End();
}
The implementation is done in the follows:
TheDownload("@"c:\Temporal\Test.txt"");
