Why I'm getting this error. My variables get the names from request, and also i tried "data.qext" but visual studio give me error.
I got "test.pdf" file in my WebsiteRoot/uploads/files/test.pdf, but still there is an error. Maybe I'm missing something?

You can try this method instead of HttpContext.Current.Server.MapPath:
Doing so, there's no need for an HttpContext.
