利用HtmlHelper压缩CSS,JS

 1 //自己拓展HtmlHelper
　　　　　　public static IHtmlString Script(this HtmlHelper helper, params string[] urls) 
 2         { 
 3             var bundleDirectory = "~/bundles/scripts/" + MakeBundleName(".js", urls); 
 4             var thisBundle = new ScriptBundle(bundleDirectory).Include(urls); 
 5             BundleTable.Bundles.Add(thisBundle); return Scripts.Render(bundleDirectory); 
 6         } 
 7         public static IHtmlString Style(this HtmlHelper helper, params string[] urls) 
 8         { 
 9             var bundleDirectory = "~/bundles/styles/" + MakeBundleName(".css", urls); 
10             var thisBundle = new StyleBundle(bundleDirectory).Include(urls); 
11             BundleTable.Bundles.Add(thisBundle); 
12             return Styles.Render(bundleDirectory); 
13         } 
14         private static string MakeBundleName(string type, params string[] urls) 
15         { 
16             var bundleSections = new List(); 
17             foreach (var item in urls) 
18             { 
19                 bundleSections.Add(item.Replace("~/", "").Replace("/", "_").Replace(type, "")); 
20             } 
21             return string.Join(";", bundleSections.ToArray()); 
22         }

对HtmlHelper进行扩展过后，在前台页面进行，将文件并排包入包中，然后扩展的Helper会把这些CSS进行压缩

1 @section head{ 
2     @Html.Style("~/Content/alice/box/box.css", 
3                 "~/Content/Alice/box/theme/orange.css", 
4                 "~/Content/Alice/tab/tab.css", 
5                 "~/Content/Benefits/CentralPurchasing.css", 
6                 "~/Content/Benefits/Index.css") 
7     }

经过压缩过后，浏览器仍然可以识别css和js的代码，并且减小了文件的大小，浏览速度大大的提高！

效果在项目发布后可以体现出来，所以记得配置IIS。
