一、配置BundleConfig.cs文件
1、首先要在App_Start 里面BundleConfig.cs 文件里面 添加要包含的css文件
2、BundleConfig就是一个微软新加的 一个打包的配置类
3、BundleConfig用来Add 各种Bundle
4、BundleConfig配置信息如下：
public class BundleConfig {public static void RegisterBundles(BundleCollection bundles) {bundles.Add(new ScriptBundle("~/bundles/jquery").Include("~/Scripts/jquery-{version}.js"));bundles.Add(new ScriptBundle("~/bundles/jqueryui").Include("~/Scripts/jquery-ui-{version}.js"));bundles.Add(new StyleBundle("~/Content1/css").Include("~/Content/site.css"));bundles.Add(new StyleBundle("~/Content1/themes/base/css").Include("~/Content/themes/base/jquery.ui.core.css","~/Content/themes/base/jquery.ui.resizable.css","~/Content/themes/base/jquery.ui.selectable.css","~/Content/themes/base/jquery.ui.accordion.css","~/Content/themes/base/jquery.ui.autocomplete.css","~/Content/themes/base/jquery.ui.theme.css"));}}
二、使用Scripts.Render、Styles.Render引用BundleConfig中的配置
1、在视图文件中使用Scripts.Render()输出脚本包，Styles.Render()输出样式包
2、Script文件引用：@Scripts.Render(virtualPath[,virtualPath1][,virtualPath2][,...])
3、CSS文件引用： @Styles.Render(virtualPath[,virtualPath1][,virtualPath2][,...])
4、实例
<!DOCTYPE html><html><head><meta charset="utf-8" /><meta name="viewport" content="width=device-width" /><title>@ViewBag.Title</title>@Styles.Render("~/Content1/css")</head><body>@RenderBody()@Scripts.Render("~/bundles/jqueryui")</body></html>
