Hello I have this routine to upload files with ASP.NET:
       String savePath = @"C:\inetpub\wwwroot\esp\docstemp1_1\";

         if (FileUpload1_1.HasFile)

            string FileExtention = System.IO.Path.GetExtension(FileUpload1_1.FileName);
            if (FileExtention == ".pdf")
                String fileName = FileUpload1_1.FileName;

                savePath += fileName;



                pdfdocumento1_1.Text = "All fine";


                pdfdocumento1_1.Text = "Is not .pdf. ";
