====================================================

需要注意的2点：

1。页面取值可以使用page.FindControl("控件的ID号")

2。string.Format("home.aspx?ID={0}",NumId);用法。

Response.Redirect(string.Format("documentlist.aspx?id={0}&page={1}&word={2}&dept={3}", cateId, AspNetPager_Doc.CurrentPageIndex, HttpUtility.UrlEncode(keyWord), txtDept.Value));
