目的：分页地址栏重写

Global.asax

两个规则：

void RegisterRoutes(RouteCollection routes)
        {
           routes.MapPageRoute("Url1", "List/{Names}", "~/New/List.aspx");
           routes.MapPageRoute("Url2", "List/{Names}/{page}", "~/New/List.aspx");  

         
        }

void Application_Start(object sender, EventArgs e)
        {
            // Code that runs on application startup
            RegisterRoutes(RouteTable.Routes);
        }

首页两个Linkbutton：

GBPath：从名为Url1的规则中取出地址。

public string GVPath(string id)
        {
            RouteValueDictionary parameters = new RouteValueDictionary() { { "Names", id }, };
            VirtualPathData vpd = RouteTable.Routes.GetVirtualPath(null, "Url1", parameters);
            return vpd.VirtualPath;
        }

        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            Response.Redirect(GVPath("Tom"));
        }

        protected void LinkButton2_Click(object sender, EventArgs e)
        {
            Response.Redirect(GVPath("Jean"));

        }

列表页：

public string Ou;
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                GridView1.DataSource = GetData(Page.RouteData.Values["Names"].ToString());
                GridView1.DataBind();
            }
        }
        public string GVPath(string page)
        {
            RouteValueDictionary parameters = new RouteValueDictionary() { { "Names", Page.RouteData.Values["Names"].ToString() }, { "page", page }, };
            VirtualPathData vpd = RouteTable.Routes.GetVirtualPath(null, "Url2", parameters);
            return vpd.VirtualPath;
        }
        private IQueryable GetData(string Li)
        {
            MyLinqDataContext md = new MyLinqDataContext();
            var AllData = from c in md.TextTBs
                          where c.Names == Li
                          select new
                              {
                                  c.ID,
                                  c.Names,
                                  c.Sex,
                                  c.DTime
                              };
            var DataCount = AllData.Count();
            var PageCount = (int)Math.Ceiling((decimal)DataCount / 2);
            int skipPage = 0;
            if (Page.RouteData.Values.ContainsKey("page"))
            {
                int page = Convert.ToInt32(Page.RouteData.Values["page"]);
                skipPage = (page - 1) * 2;
            }
            var TrueData = AllData.Skip(skipPage).Take(2);
            StringBuilder sb = new StringBuilder();
            for (int i = 1; i <= PageCount; i++)
            {
                sb.AppendFormat("<a href=\"" + GVPath(i.ToString()) + "\">" + i + "</a>  ");
            }
            Ou = sb.ToString();
            return TrueData;
        }
