how to download a file from the server in Asp.net 2.0

If you need HTTP download, you can use my HTTPDownloader application for sample. I posted full source code in my past answer:
how to download a file from internet[^].

Even though this is a console application, you can take just the downloading code which is simple enough. One important feature is implemented: possibility to continues download of partially downloaded file, if the process was broken in the middle, before download of a file is complete.

Now, if you want FTP download, the code is different.

One option is using WebRequestMethods.Ftp.DownloadFile: http://msdn.microsoft.com/en-us/library/system.net.webrequestmethods.ftp.downloadfile.aspx[^].

Another option is using FtpWebRequest class: http://msdn.microsoft.com/en-us/library/system.net.ftpwebrequest.aspx[^].

Try This One..

string filepath = Server.MapPath("-- File Path Here --");
// Create New instance of FileInfo class to get the properties of the file being downloaded
FileInfo myfile = new FileInfo(filepath);

// Checking if file exists
if (myfile.Exists)
{

// Clear the content of the response
Response.ClearContent();

// Add the file name and attachment, which will force the open/cancel/save dialog box to show, to the header
Response.AddHeader("Content-Disposition", "attachment; filename=" + myfile.Name);

// Add the file size into the response header
Response.AddHeader("Content-Length", myfile.Length.ToString());

// Set the ContentType
//    Response.ContentType = ReturnExtension(myfile.Extension.ToLower());

// Write the file into the response (TransmitFile is for ASP.NET 2.0. In ASP.NET 1.1 you have to use WriteFile instead)
Response.TransmitFile(myfile.FullName);

// End the response
Response.End();

}
