Thread: Asp.net code for download file

Hi. I am working on live project where I use asp.net as front end and SQL as backend. I want one code for my application where user can download file from my website. I tried different code but none of them worked out for me. If you have any code the let me know that is highly appreciated.

The script that I have mentioned below will definitely help you.

Code:

Response.ContentType = "image/jpeg";
Response.AppendHeader("Content-Disposition","attachment; filename=test.jpg");
Response.TransmitFile( Server.MapPath("~/images/test.jpg") );
Response.End();

Have you tried below code for download file? If not then try this code:

Code:

<%
try
{
   System.String filename = "myFile.txt";

   // set the http content type to "APPLICATION/OCTET-STREAM
   Response.ContentType = "APPLICATION/OCTET-STREAM";
   
   // initialize the http content-disposition header to
   // indicate a file attachment with the default filename
   // "myFile.txt"
   System.String disHeader = "Attachment; Filename="" + filename +
      """;
   Response.AppendHeader("Content-Disposition", disHeader);

   // transfer the file byte-by-byte to the response object
   System.IO.FileInfo fileToDownload = new
      System.IO.FileInfo("C:\downloadJSP\DownloadConv\myFile.txt");
   Response.Flush();
   Response.WriteFile(fileToDownload.FullName);}
catch (System.Exception e)
// file IO errors
{
   SupportClass.WriteStackTrace(e, Console.Error);
}
%>
