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。
