第一篇,我简略描述了一下我的cms标签所表示的含义。anCMS(c#版)第一篇绑定数据 第二篇,我将展示了标签背后真正运行的代码。asp.net的cms 原理篇 好像开源有点多余,核心代码就下面这些。 复制代码 代码如下: using System; using System.Collections; using System.Collections.Generic; using System.Linq; using System.Text; namespace an.helper { /// <summary> /// 查找html页面中可以转换成aspx页面的方法 的正则表达式 /// </summary> public class HtmlToAspxMethod { private static T_Validate tv=new T_Validate(); public static string ConvertMethodNameHtmlToAspx(string methodName) { string str=""; switch(methodName) { case "list ": str = "TextFile"; break; //文档 case "listpager ": str = "TextFilePager"; break; //文档分页 case "alist ": str = "Article"; break;//文章列表 case "alistpager ": str = "ArticlePager"; break;//文章分页 case "plist ": str = "Products"; break;//产品列表 case "plistpager ": str = "ProductsPager"; break;//产品分页 case "olist ": str = "One"; break;//单页列表 case "olistpager ": str = "OnePager"; break;//单页分页 case "clist ": str = "Category"; break; //分类列表 case "clistpager ": str = "CategoryPager"; break; //分类列表 case "llist ": str = "Link"; break;//连接列表 case "llistpager ": str = "LinkPager"; break;//连接分页 case "ilist ": str = "Images"; break;//图片集列表 case "ilistpager ": str = "ImagesPager"; break;//图片集分页 default: break; } return str; } public static string MethodListName = "list |listpager |alist |alistpager |plist |plistpager |olist |olistpager |clist |clistpager |llist |llistpager |ilist |ilistpager "; public static string MethodFiledName = "filed|num|category|keyword|sort|page|id"; /// <summary> /// 所有方法的入口,第一次运行时遍历该方法。 /// </summary> public static string AllMethodContentRegex = "<!--{an:(" + MethodListName + ").*?}-->[\\s\\S]*?<!--{/an}-->"; public static List<string> AllMethodContent(string content) { return Method.RegexStr(AllMethodContentRegex, content); } /// <summary> /// 获取所有的方法 /// </summary> public static string AllMethodRegex = "<!--{an:(" + MethodListName + ")[^}]*}-->"; public static List<string> AllMethod(string content) { return Method.RegexStr(AllMethodRegex, content); } /// <summary> /// 获取方法的函数名称 /// </summary> public static string MethodNameRegex = "<!--{an:(" + MethodListName + ")"; public static string MethodName(string content) { string str = ""; var c=Method.RegexStr(MethodNameRegex, content); if (c.Count>0) { str = c[0].ToString(); } return str.Replace("<!--{an:", ""); } /// <summary> /// 获取方法的字段和值 /// </summary> public static string MethodFiledRegex = "(" + MethodFiledName + ")=\\[[^]]+]"; public static Hashtable MethodFiled(string content) { Hashtable ht = new Hashtable(); foreach (string s in Method.RegexStr(MethodFiledRegex, content)) { string[] arr = s.Split('='); ht.Add(arr[0], arr[1].Replace("[", "").Replace("]", "")); } return ht; } public static string JsIncludeRegex = "<script.*rel=\"share\"[^>]*></script>"; public static string[] JsInclude(string html) { string js = ""; List<string> list_include = Method.RegexStr(JsIncludeRegex, html); foreach (string inc in list_include) { List<string> includeList = Method.RegexStr(@"\w+(?=\.js)", inc); if (includeList != null) { js += includeList[0] + "(); "; html = html.Replace(inc, "<!--#include file=\"Share/" +includeList[0] + ".ascx\"--> "); } } return new string[] { js, html }; } /// <summary> /// 占位符 /// </summary> public static string ValueOneRegex = @"\${\d+}"; public static string ValueOne(string content) { foreach (string s in Method.RegexStr(ValueOneRegex, content)) { string num = s.Replace("${", "").Replace("}", ""); content = content.Replace(s, "<%=a[" + num + "]%>"); } return content; } public static string ValueOneToStringFormartRegex = @"\${\d+\|.*?}"; public static string ValueOneToStringFormat(string content) { foreach (string s in Method.RegexStr(ValueOneToStringFormartRegex, content)) { string str = s.Replace("${", "").Replace("}", ""); string[] arr = str.Split('|'); string num = arr[0].ToString(); string formart = arr[1].ToString(); content = content.Replace(s, "<%=TimeFormart(a[" + num + "],\"" + formart + "\")%>"); } return content; } public static string UrlRouteRegex = @"\$href\[\w+\]\[.*?\]"; public static string UrlRoute(string content) { foreach (string s in Method.RegexStr(UrlRouteRegex, content)) { //$href[index][{"aaa","bbb"},{"ccc","ddd"}] //<%=UrlRoute("",new string[,]{{"aaa","bbb"},{"ccc","ddd"}});%> string urlRoute = s.Replace("$href[", "<%=UrlRoute(\"").
