td id = " 1 " class = " ControlPanelTabInactive " align = " center " nowrap >
< a href = " =Globals.GetSiteUrls().MyFavorites " >```
= ResourceManager.GetString( " MyFavorites_Title " )
1修改： < td colspan = 11 class = " ControlPanelTabLine " >< img width = " 1 " height = 1 alt = "" >
2跨跃列数

4**五.增加相应文件
5
6表现层1，收藏夹主视图
7** 在web / user / 目录增加MyFavorites.aspx，最终用户页面
8在Controls\Views目录增加MyFavoritesView.cs,页面视图服务器控件（主要表现为页面处理逻辑）
9界面视图：在Web\Themes\ default \Skins中增加View \- MyFavorites.ascx 收藏夹视图（主要表现为页面UI）
10
11**组件**
12在Components目录增加Favorites.cs（相当于业务逻辑层，加s表业务处理），此例中未在子目录Components / Components中增加Favorite.cs(相当于业务实体层，未加s表实体)，因并不需要，完整的Asp.net forums模式应该还有这一层。
13
14**表现层2，用户点击收藏按钮后呈现的UI
15** （这个比较简单）
16在web目录增加MyFavoritesAdd.aspx文件
17处理加入收藏时服务器控件, 在Controls目录增加MyFavoritesAdd.cs（页面处理逻辑）
18在Web\Themes\ default \Skins中增加Skin \- MyFavoritesAdd.ascx将主题加入收藏时的视图(UI)
19
20**六．数据库**
21**增加表forums_Favorites**
22UserID int 4 0
23ThreadID int 4 0
24FavoriteDate datetime 8 0
25
26**创建存储过程forums_Favorites_CreateDelete**
27CREATE procedure forums_Favorites_CreateDelete
28(
29@UserID int ,
30@ThreadID int ,
31@Action int
32)
33AS
34BEGIN

55BEGIN
56DELETE
57forums_Favorites
58WHERE
59UserID = @UserID AND
60ThreadID = @ThreadID

71**七.数据处理
72** **1** **.Components\Provider\ForumsDataProvider.cs增加
