Something less verbose, and works in all browsers (in my experience):
if (Request.Params["file"] != null)
{
String PathToFile = Server.MapPath("") + "\\" +
Request.Params["file"].ToString();
Response.ContentType = "application/octet-stream";
Response.AddHeader("content-disposition", "attachment;filename=" +
Request.Params["file"]);
Response.WriteFile(PathToFile);
}
The above expects a filename to be passed over the URL...
Download.aspx?file=test.pdf&dummy
I put in the &dummy at the end of the URL to conteract a dumb bug in a couple versions
of IE that uses the file extension and ignores the fact that you want to download the
file instead of view it inline of the browser.
It should be trivial to write the part of your code to get the filepath from a
database, keyed by an ID passed through the URL.
