        <asp:Button runat="server" ID="btnupload" Text="Upload"
            onclick="btnupload_Click"/>&nbsp;<br/>

        <asp:Label runat="server" ID="Label1"></asp:Label> 

</div>

Filename.aspx.cs

protected void btnupload_Click(object sender, EventArgs e)
    {
      string tempPath =          System.Configuration.ConfigurationManager.AppSettings["FolderPath"];
       string savepath = Server.MapPath(tempPath);
        for(int i=0;i<Request.Files.Count;i++)
        {            
            HttpPostedFile hpf = Request.Files[i];
            string filename = hpf.FileName;
            hpf.SaveAs(savepath + @"\" + filename);
        }

    }
