这个由微软提供的组件已经编译好了的,无需自己再写代码,直接用就行:)
对于Web.Config设置一下:
在<configuration>节最开始加上:
<configSections> <section name="RewriterConfig" type="URLRewriter.Config.RewriterConfigSerializerSectionHandler, URLRewriter" /> </configSections> 在<configuration>节中加上:
<RewriterConfig> <Rules> <RewriterRule> <LookFor>~/News,(d{4}),(d{1,2}),(d{1,2}),(d{1,9}).aspx</LookFor> <SendTo>~/news_view.aspx?newsid=$4</SendTo> </RewriterRule> <RewriterRule> <LookFor>~/(d{4})/(d{2})/Default.aspx</LookFor> <SendTo><![CDATA[~/news_view.aspx?year=$1&month=$2]]></SendTo> </RewriterRule> </Rules> </RewriterConfig> 在<system.web>节加上:
<httpModules> <add type="URLRewriter.ModuleRewriter, URLRewriter" name="ModuleRewriter" /> </httpModules> 处理一下链接:
news.aspx
private void Page_Load(object sender, System.EventArgs e) { // 在此处放置用户代码以初始化页面 DataTable dt=new DataProvider().GetNewsToIndexPage(1); //格式化URL UrlFormat formats=new UrlFormat();
lbNews.Text = "<ul>"; if (dt.Rows.Count>0) { int counter=0; while (counter < dt.Rows.Count) { lbNews.Text += "<li><a href="" + formats.NewsUrl((DateTime)dt.Rows[counter]["NewsPubTime"],Convert.ToInt32(dt.Rows[counter]["NewsID"])) + "" target="_blank">" + dt.Rows[counter]["NewsTitle"].ToString() + "</a></li>"; counter++; } } else { lbNews.Text="<li style="color:red">暂无内容</li>"; } lbNews.Text += "</ul>"; dt.Clear(); dt.Dispose(); } UrlFormat.cs
public class UrlFormat {
public UrlFormat() { }
public virtual string NewsUrl(DateTime dt,int NewsID) { return GetUrl("News,{0},{1},{2}," + NewsID + ".aspx",dt.Year,dt.Month,dt.Day); }
protected virtual string GetUrl(string pattern, params object[] items) { return string.Format(pattern,items); }
}
格式化为: news,2004,8,13,123.aspx
指向: news.aspx?参数=some parameter
