On the button click event, 1) const string fName = @"C:	estfile.txt"; //file should be available on the server FileInfo fi = new FileInfo(fName); long sz = fi.Length; Response.ClearContent(); Response.ContentType = text/plain; Response.AddHeader("Content-Disposition", string.Format("attachment; filename = {0}",System.IO.Path.GetFileName(fName))); Response.AddHeader("Content-Length", sz.ToString("F0")); Response.TransmitFile(fName); Response.End(); 2) WebClient client = new WebClient(); client.DownloadFile(SourceFileName, destinationfilename);
