datalist和gridview遍历还有hyperlink

foreach(DataListItem i in dlhouse.Items)        {            HyperLink lnktitle = (HyperLink)i.FindControl("lnktitle");

            lnktitle.NavigateUrl = "../../SecondhandHouseOfAskRent.aspx?id=" + lnktitle.NavigateUrl.ConvertToEncryptString();                    }

 

 

 foreach(GridViewRow gvr in GridView1.Rows)        {            HyperLink lnkrealname = (HyperLink)gvr.FindControl("lnkrealname");

            lnkrealname.NavigateUrl = "AdminAdd.aspx?id=" + lnkrealname.NavigateUrl.ConvertToEncryptString();        }
