Problem

I have a asp.net FileUpload control. I can successfully upload file to store in session, but when I am tring to get its inputstream (I'm store file in HttpPosterFile) I'm getting error Cannot access a closed file ``` tr.PostedFile //<== HttpPostedFile; byte[] byteArray = null; using (var binaryReader = new BinaryReader(tr.PostedFile.InputStream)) { byteArray = binaryReader.ReadBytes(tr.PostedFile.ContentLength); } ```
