[步骤]
1.执行SetupDataBase.bat,安装示例数据库所需内容.
2.使用Vs2005打开SqlHelperTest.csproj,编译运行.

其实asp.net forums2就是像搭积木，现以收藏夹功能实例看一下asp.net forums的结构及组件设计，希望给朋友以参考。
示例：帖子收藏功能(by venjiang 20040912) √
一.增加资源文件项目
修改Web\Languages\zh-CN\Resources.xml，增加
<!-- 收藏夹 -->
<resource name = "MyFavorite_Title">收藏夹</resource>
<resource name = "MyFavorite_Description">我收藏的主题</resource>
<!-- 收藏夹－结束 -->
二．增加站点url
修改E:\WWW\cnforums0804\Web\SiteUrls.config，增加
<url name="user_MyFavorite" path="/User/MyFavorite.aspx" />
三．增加属性
修改Components\Components\SiteUrls.cs，增加
// 收藏夹 by venjiang 0911
public string MyFavorite
{
get { return paths["MyFavorite"]; }
}
四.修改相应的界面文件
修改Web\Themes\default\Skins\View-MyForums.ascx，
修改Web\Themes\default\Skins\View-PrivateMessages.ascx
修改Web\Themes\default\Skins\Skin-EditProfile.ascx
在UserPrivateMessages后增加
<td width="15"> </td>
<td id="1" class="ControlPanelTabInactive" align="center" nowrap>
<a href="<%=Globals.GetSiteUrls().MyFavorites%>"><%=ResourceManager.GetString("MyFavorites_Title")%></a>
</td>
修改： <td colspan=11 class="ControlPanelTabLine"><img width="1" height=1 alt=""></td>跨跃列数
五.增加相应文件
表现层1，收藏夹主视图
在web/user/目录增加MyFavorites.aspx，最终用户页面
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）
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）
组件
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。
表现层2，用户点击收藏按钮后呈现的UI
（这个比较简单）
在web目录增加MyFavoritesAdd.aspx文件
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）
在Web\Themes\default\Skins中增加Skin-MyFavoritesAdd.ascx将主题加入收藏时的视图(UI)
六．数据库
增加表forums_Favorites
UserID int 4 0
ThreadID int 4 0
FavoriteDate datetime 8 0
创建存储过程forums_Favorites_CreateDelete
CREATE procedure forums_Favorites_CreateDelete
(
@UserID int,
@ThreadID int,
@Action int
)
AS
BEGIN
IF @Action = 0
BEGIN
-- Does the user already have the ability to see this thread?
IF EXISTS (SELECT UserID FROM forums_Favorites WHERE UserID = @UserID and ThreadID = @ThreadID)
return
INSERT INTO
forums_Favorites
VALUES
(
@UserID,
@ThreadID,
getdate()
)
RETURN
END
IF @Action = 2
BEGIN
DELETE
forums_Favorites
WHERE
UserID = @UserID AND
ThreadID = @ThreadID
RETURN
END
END
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
七.数据处理
1.Components\Provider\ForumsDataProvider.cs增加
#region 收藏夹
public abstract void CreateFavorites(ArrayList users, int threadID);
public abstract void DeleteFavorites(int userID, ArrayList deleteList);
#endregion
2. Data Providers\SqlDataProvider\SqlDataProvider.cs增加实现方法
#region #### 收藏夹 #### by venjiang 0912

/// <param name="userID">用户ID</param>

#endregion
八.增加新方法
在Components\Threads.cs增加新的重载方法,以不必修改原来的方法调用.
// 为了不影响以前的程序,单独加一个重载方法,以获得收藏夹主题
public static ThreadSet GetThreads(int forumID, int pageIndex, int pageSize, int userID, DateTime threadsNewerThan, SortThreadsBy sortBy, SortOrder sortOrder, ThreadStatus threadStatus, ThreadUsersFilter userFilter, bool activeTopics, bool unreadOnly, bool unansweredOnly, bool returnRecordCount,bool favoriteOnly) // 多了一个参数favoriteOnly
{
ForumContext forumContext = ForumContext.Current;
string anonymousKey = "Thread-" + forumID + pageSize.ToString() + pageIndex.ToString() + threadsNewerThan.DayOfYear.ToString() + sortBy + sortOrder + activeTopics.ToString() + unansweredOnly.ToString() + favoriteOnly.ToString();
ThreadSet threadSet;
// If the user is anonymous take some load off the db
//
if (userID == 0)
{
if (forumContext.Context.Cache[anonymousKey] != null)
return (ThreadSet) forumContext.Context.Cache[anonymousKey];
}
// Create Instance of the IDataProvider
//
ForumsDataProvider dp = ForumsDataProvider.Instance();
// Get the threads
//
threadSet = dp.GetThreads(forumID, pageIndex, pageSize, userID, threadsNewerThan, sortBy, sortOrder, threadStatus, userFilter, activeTopics, unreadOnly, unansweredOnly, returnRecordCount,favoriteOnly);
if (userID == 0)
forumContext.Context.Cache.Insert(anonymousKey, threadSet, null, DateTime.Now.AddMinutes(2), TimeSpan.Zero, CacheItemPriority.Low, null);
return threadSet;
}
九．业务逻辑层
Components目录中增加Favorites.cs，实现主题的增加删除方法
public static void AddFavoritesPost (int userID,int threadID) {
ForumsDataProvider dp = ForumsDataProvider.Instance();
dp.CreateFavorites(userID, threadID);
}
/// <summary>
/// 删除收藏
/// </summary>
/// <param name="userID">用户ID</param>
/// <param name="deleteList">删除列表</param>
public static void DeleteFavorites (int userID, ArrayList deleteList) {
//
ForumsDataProvider dp = ForumsDataProvider.Instance();
dp.DeleteFavorites(userID, deleteList);
}
十．表现层调用
1.收藏夹主视图加载收藏主题列表
threadSet = Threads.GetThreads(forumID, pager.PageIndex, pager.PageSize, Users.GetUser().UserID, dateFilterValue, threadSortddl.SelectedValue, sortOrderddl.SelectedValue, ThreadStatus.NotSet, ThreadUsersFilter.All, false, hideReadPosts.SelectedValue, false, true,true);
注意最后一个参数是true,即返回收藏夹的数据集。
2.增加主题到收藏夹
Favorites.AddFavoritesPost(user.UserID,post.ThreadID);
HttpContext.Current.Response.Redirect(Globals.ApplicationPath+"/MyFavoritesAdd.aspx",true);
3.删除收藏的主题
Favorites.DeleteFavorites（…）

}
Pager类,用于分页, Controls\Utility\Pager.cs
首先增加成员变量:
/// venjiang:增加跳转页输入文本框
/// </summary>
TextBox gotoPage;
/// <summary>
/// venjiang:增加跳转按钮
/// </summary>
LinkButton gotoButton;
其次增加控件:
/// <summary>
/// 跳转按钮
/// </summary>
void AddGotoButton()
{
this.gotoButton=new LinkButton();
this.gotoButton.ID="GoTo";
this.gotoButton.Text="Go";
this.gotoButton.Click += new System.EventHandler(PageIndex_Click);
Controls.Add(gotoButton);
}
/// <summary>
/// 增加跳转页输入框
/// </summary>
void AddGotoPage()
{
this.gotoPage=new TextBox();
this.gotoPage.Width=30;
this.gotoPage.ID="GoToPage";
//this.gotoPage.Text="3";
this.gotoPage.TextChanged += new System.EventHandler(PageText_Change);
//this.gotoPage.EnableViewState=true;
Controls.Add(gotoPage);
}
增加跳转页文本框文本改变事件:
void PageText_Change(Object sender,EventArgs e)
{
int i = 1;
try
{
i = Convert.ToInt32(this.gotoPage.Text.Trim().ToString());
if(i < 1)
{
i = 1;
this.gotoPage.Text="1";
}
if(i > CalculateTotalPages())
{
i = CalculateTotalPages();
this.gotoPage.Text=i.ToString();
}
}
catch
{
this.gotoPage.Text="";
return;
}
this.gotoButton.CommandArgument = (i-1).ToString();
}
增加呈现方法:
void RenderGotoPage(HtmlTextWriter writer)
{
Literal l,m;
l = new Literal();
l.Text = " ";
l.RenderControl(writer);
this.gotoPage.RenderControl(writer);
this.gotoButton.RenderControl(writer);
m = new Literal();
m.Text = " ";
m.RenderControl(writer);
}
最后将所创建的方法分别添加到相应用方法中:
在CreateChildControls()方法尾部,增加this.AddGotoPage();this.AddGotoButton();
Render(…)方法尾部,增加this.RenderGotoPage(writer);
