   WebClient req = new WebClient();
   HttpResponse response = HttpContext.Current.Response;
   response.Clear();
   response.ClearContent();
   response.ClearHeaders();
   response.Buffer = true;
   response.AddHeader("Content-Disposition", "attachment;filename=\"" + strURL + "\"");
   byte[] data = req.DownloadData(Server.MapPath(strURL));
   response.BinaryWrite(data);

Solution 1

I assume this line is the error:

byte[] data = req.DownloadData(Server.MapPath(strURL));

You did MapPath on strURL already. So, it's already a local path, but you pass it to a method that expects a virtual path to convert.

still one help if you can

when my file get downloaded it name is like my whole path foe e.g.
D-AdminAppJobportalsUtilsApplicantFiles20directory

is there be any way by which i can change the downloaded file name?

You can change it any way you want. You write the filename as strURL in to the header. You can use Path.GetFileName to get just the file name, or create any file name you like, just put it in to that header.

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Download")
{
string Filepath = e.CommandArgument.ToString();
string path = MapPath(Filepath);
byte[] bts = System.IO.File.ReadAllBytes(path);

Response.Clear();
Response.ClearHeaders();
Response.AddHeader("Content-type", "application/octect-stream");
Response.AddHeader("Content-Length", bts.Length.ToString());
Response.AddHeader("Content-Disposition", "attachment; Filepath=" + Filepath);
Response.BinaryWrite(bts);
Response.Flush();
Response.End();
}
}

Having the same problem, how can I fix this?
