Allowing user to download from my site through Response.WriteFile()

Question

I am trying to programatically download a file through clicking a link, on my site (it\'s a .doc file sitting on my web server). This is my code:

string File         


        

Answer 1

Rather than having a button click event handler you could have a download.aspx page that you could link to instead.

This page could then have your code in the page load event. Also add Response.Clear(); before your Response.ContentType = "Application/msword"; line and also add Response.End(); after your Response.WriteFile(fileInfo.FullName); line.

Answer 2

Try a slightly modified version:

string File = Server.MapPath(@"filename.doc");
string FileName = "filename.doc";

if (System.IO.File.Exists(FileName))
{

    FileInfo fileInfo = new FileInfo(File);


    Response.Clear();
    Response.ContentType = "Application/msword";
    Response.AddHeader("Content-Disposition", "attachment; filename=" + fileInfo.Name);
    Response.WriteFile(fileInfo.FullName);
    Response.End();
}

Oh, you shouldn't do it in button click event handler. I suggest moving the whole thing to an HTTP Handler (.ashx) and use Response.Redirect or any other redirection method to take the user to that page. My answer to this question provides a sample.

If you still want to do it in the event handler. Make sure you do a Response.End call after writing out the file.
