ThreadPool.QueueUserWorkItem NullReferenceException

Question

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?

Do you have an HttpContext? Looks like you HttpContext.Current.Sever is null... — Leniel Maccaferri

I mean... when you debug, if you pass your mouse over HttpContext.Current.Sever... does it show something or is it null? — Leniel Maccaferri

You can try this method instead of HttpContext.Current.Server.MapPath:

System.Web.Hosting.HostingEnvironment.MapPath()

Doing so, there's no need for an HttpContext.

Since i got my error with HttpContext.Current.Sever.MapPath inside my other functions, this definitely solve my problem. THANKS!
