asp.net Bundle功能扩展

前言
新建Asp.net MVC4项目的时候,在Global.asax.cs里面发现多了一句代码
BundleConfig.RegisterBundles(BundleTable.Bundles)
google了以后终于弄清楚了这个的作用，发现这个东西确实非常实用，且功能强大，能够压缩合并js和CSS，但是目前的使用起来不是特别好，如果添加js或者css文件的话，需要修改BundleConfig的代码。
这里我自己简单修改了BundleConfig，对这个进行简单的扩展。
下面贴出代码：
先贴配置文件BundleConfig.xml(文件放在网站目录下路径见代码中变量BundleConfigPath)

复制代码代码如下:

 
~/Scripts/jquery-{version}.js 
 
~/Scripts/jquery-ui-{version}.js 
 
~/Scripts/jquery.unobtrusive* 
~/Scripts/jquery.validate* 
 
~/Scripts/modernizr-* 
 
~/Views/Home/addda.js 
 
~/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.button.css 
~/Content/themes/base/jquery.ui.dialog.css 
~/Content/themes/base/jquery.ui.slider.css 
~/Content/themes/base/jquery.ui.tabs.css 
~/Content/themes/base/jquery.ui.datepicker.css 
~/Content/themes/base/jquery.ui.progressbar.css 
~/Content/themes/base/jquery.ui.theme.css 
 
~/Content/site.css

代码文件：BundleConfig.cs

复制代码代码如下:

 
public class BundleConfig 
{ 
public static string BundleConfigPath = "~/Config/BundleConfig.xml"; 
///  
/// Register Bundles From XML 
///  
///  
public static void RegisterBundles(BundleCollection bundles) 
{ 
XmlDocument doc = new XmlDocument(); 
doc.Load(HttpContext.Current.Server.MapPath(BundleConfigPath)); 
XmlNode root = doc.DocumentElement; 
// Regester Script 
XmlNodeList ScriptList = root.SelectNodes("Scripts/Script"); 
if (ScriptList != null && ScriptList.Count > 0) 
{ 
foreach (XmlNode node in ScriptList) 
{ 
string path = CheckNodeRegedit(node); 
if (string.IsNullOrEmpty(path)) continue; 
var bound = new ScriptBundle(path); 
List files = GetFilesFormNode(node); 
if (files.Count > 0) 
{ 
bound.Include(files.ToArray()); 
bundles.Add(bound); 
} 
} 
} 
// Regester Style 
XmlNodeList StyleList = root.SelectNodes("Styles/Style"); 
if (StyleList != null && StyleList.Count > 0) 
{ 
foreach (XmlNode node in StyleList) 
{ 
string path = CheckNodeRegedit(node); 
if (string.IsNullOrEmpty(path)) continue; 
var bound = new StyleBundle(path); 
List files = GetFilesFormNode(node); 
if (files.Count > 0) 
{ 
bound.Include(files.ToArray()); 
bundles.Add(bound); 
} 
} 
} 
doc = null; 
} 
///  
/// 如果内容为空则不添加 
///  
///  
///  
private static List GetFilesFormNode(XmlNode node) 
{ 
List files = new List(); 
foreach (XmlNode nodeFile in node.ChildNodes) 
{ 
if (!string.IsNullOrEmpty(nodeFile.InnerText.Trim())) 
files.Add(nodeFile.InnerText.Trim()); 
} 
return files; 
} 
///  
/// 检查注册的Node 
///  
///  
///  
private static string CheckNodeRegedit(XmlNode node) 
{ 
XmlAttribute pathAtt = node.Attributes["Path"]; 
string path = string.Empty; 
if (pathAtt == null || string.IsNullOrEmpty(pathAtt.Value.Trim()) || node.ChildNodes.Count == 0) 
return string.Empty; 
else 
return pathAtt.Value.Trim(); 
} 
}
