使用静态资源压缩可以合并静态资源文件减少客户端请求数量，压缩文件大小，减少网络流量的损耗。

注：只有通过web.config关闭调试功能，压缩才会生效

<system.web>
    <compilation debug="false" targetFramework="4.0" />

 

需要用到Microsoft ASP.NET Web Optimization，安装方法：

Install-Package Microsoft.AspNet.Web.Optimization

 

参考MVC构架的方法，App_Start中添加BundleConfig.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Optimization;

namespace EmptyWebForm
{
    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 ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.unobtrusive*",
                        "~/Scripts/jquery.validate*"));


          
            bundles.Add(new ScriptBundle("~/bundles/WebFormsJs").Include(
                  "~/Scripts/WebForms/WebForms.js",
                  "~/Scripts/WebForms/WebUIValidation.js",
                  "~/Scripts/WebForms/MenuStandards.js",
                  "~/Scripts/WebForms/Focus.js",
                  "~/Scripts/WebForms/GridView.js",
                  "~/Scripts/WebForms/DetailsView.js",
                  "~/Scripts/WebForms/TreeView.js",
                  "~/Scripts/WebForms/WebParts.js"));

            bundles.Add(new ScriptBundle("~/bundles/MsAjaxJs").Include(
                "~/Scripts/WebForms/MsAjax/MicrosoftAjax.js",
                "~/Scripts/WebForms/MsAjax/MicrosoftAjaxApplicationServices.js",
                "~/Scripts/WebForms/MsAjax/MicrosoftAjaxTimer.js",
                "~/Scripts/WebForms/MsAjax/MicrosoftAjaxWebForms.js"));

            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                "~/Scripts/modernizr-*"));

            bundles.Add(new StyleBundle("~/bundles/themes/base/style").Include("~/Content/themes/base/style*"));
             
        }
    }
}

在themes下添加style1.css与style2.css作为测试

1 body {
2 border:solid 1px red
3 }
style1.css
1 input {
2 color:red
3 }
style2.css

修改页面应用css及js方法如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Index.aspx.cs" Inherits="EmptyWebForm.Index" %>

<!DOCTYPE html>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <title></title>
    <%:System.Web.Optimization.Scripts.Render("~/bundles/jquery") %>

    <%:System.Web.Optimization.Scripts.Render("~/bundles/WebFormsJs")%>

    <%:System.Web.Optimization.Styles.Render("~/bundles/themes/base/style")%>

    
</head>
<body>
    <form id="form1" runat="server">
    <div>
    
    </div>
    </form>
</body>
</html>

页面请求结果中，根据配置会自动合并压缩文件，详细如下：

css压缩效果如下，两个样式表文件被合并为一个并且进行了压缩
