谁能帮我把VB的脚本翻译成C#的~

只要我是想在前台写page_load这个事件
<script runat="server">
sub Page_Load
if Not Page.IsPostBack then
  dim mycdcatalog=New DataSet
  mycdcatalog.ReadXml(MapPath("cdcatalog.xml"))
  cdcatalog.DataSource=mycdcatalog
  cdcatalog.DataBind()
end if
end sub
</script>

C# code

protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                using (System.Data.DataSet ds = new System.Data.DataSet())
                {
                    ds.ReadXml(Server.MapPath("cdcatalog.xml"));
                    cdcatalog.DataSource = ds;
                    cdcatalog.DataBind();
                }
            }
        }

我要写在前台~~
