Way 1:
UpLoadFile webcontrol can finish it easy
FileUpLoad ful_load =new FileUpLoad(); //FileUpLoad is a kind of control
…..
Set the upload file name;
ful_load.SaveAs(Server.MapPath(ful_load.FileName));
that’s ok!
Way 2: can upload many files in one time
if (Request.Files.Count < 1)
return;
HttpPostedFile file = Request.Files[0];
if (file != null && file.FileName.Length > 0)
{
file.SaveAs(Path.Combine(GetCurDir(), Path.GetFileName(file.FileName)));
file.InputStream.Close();
}
