Answer 1

I think it is an issue with the browser sending the full file path Try this:

if (file.ContentLength > 0)
{ 
 string filename = Server.MapPath("~" + "/upload/" + System.IO.Path.GetFilename(file.FileName)); 
 file.SaveAs(filename); Line 24:             
}

Are you sure you have specified the correct MIME type on the HTML form? It must be "multipart/form-data"
