        <asp:FileUpload ID="FileUpload1" runat="server" />
        <asp:LinkButton ID="LinkButton1" runat="server">upload multiple files</asp:LinkButton>

protected void Button1_Click(object sender, EventArgs e)
       {
           if (FileUpload1.HasFiles)
           {
               foreach (HttpPostedFile uploadedFile in FileUpload1.PostedFiles)
               {
                   uploadedFile.SaveAs(System.IO.Path.Combine(Server.MapPath("~/Images/"),
                   uploadedFile.FileName));
                   Span1.Text += String.Format("{0}<br />", uploadedFile.FileName);
               }
           }
