Asp.net mvc3.0 razor Website full-site scripting and style reference solution

Xml version = "1.0"?> <Configuration> <system. web> <compilation debug = "true" targetFramework = "4.0"/> </system. web> <deleetask> <add key = "css_css1" value = "~ /Views/Center/css1.cshtml "/> <add key =" js_js1 "value = "~ /Views/Center/js1.cshtml "/> </appSettings> </configuration> 3. encapsulate the reading method using System; using System. configuration; using System. IO; using System. text; using System. web; using System. web. mvc; using System. linq; namespace DiscussCenter. ctrl. utility {// <summary> /// Html object extension class /// </summary> public static class WebExtension {/// <summary> /// import the Css file/ /// </summary> /// <param name = "url"> </param> /// <param nam E = "cssName"> style name </param> // <returns> </returns> public static MvcHtmlString IncludeCss (this UrlHelper url, params string [] cssName) {StringBuilder str = new StringBuilder (); foreach (string css in cssName) {str. append (string. format ("<link type = \" text/css \ "rel = \" stylesheet \ "href = \" {0} \ "/>", url. content (GetIncludeSettingValue ("css _" + css);} return new MvcHtmlString (str. toString ();} // <su Mmary> /// import the Js file /// </summary> /// <param name = "url"> </param> /// <param name = "cssName"> script file name </param> /// <returns> </returns> public static MvcHtmlString IncludeJs (this UrlHelper url, params string [] jsName) {StringBuilder str = new StringBuilder (); foreach (string js in jsName) {str. append (string. format ("<script type = \" text/javascript \ "src = \" {0 }\ "> </script>", url. content (GetIncludeSettingV Alue ("js _" + js);} return new MvcHtmlString (str. toString ();} // <summary> // get custom Include. the value of the deleetting node in the config file /// </summary> www.2cto.com // <param name = "key"> node name </param> /// <returns> </returns> public static string GetIncludeSettingValue (string key) {string indexConfigPath = Path. combine (HttpContext. current. request. physicalApplicationPath, "Include. config "); if (!
