asp.net bundle function Extension _ practical skills

Preface
New ASP.net MVC4 project, in the Global.asax.cs found a more than a code
Bundleconfig.registerbundles (Bundletable.bundles)
Google after finally understand the role of this, found this thing is really very practical, and powerful, can compress merge JS and CSS, but the current use is not particularly good, if you add JS or CSS files, you need to modify the Bundleconfig code.
Here I have simply modified the bundleconfig and made a simple extension of this.
post the code below：
First paste the configuration file Bundleconfig.xml (file in the site directory in the path to see the code in the variable Bundleconfigpath)

Copy Code code as follows:

<?xml version= "1.0" encoding= "Utf-8"?>
<root>
<Scripts>
<script path= "~/bundles/jquery" >
<File>~/Scripts/jquery-{version}.js</File>
</Script>
<script path= "~/bundles/jqueryui" >
<File>~/Scripts/jquery-ui-{version}.js</File>
</Script>
<script path= "~/bundles/jqueryval" >
<File>~/Scripts/jquery.unobtrusive*</File>
<File>~/Scripts/jquery.validate*</File>
</Script>
<script path= "~/bundles/modernizr" >
<File>~/Scripts/modernizr-*</File>
</Script>
<script path= "~/bb/aa" >
<File>~/Views/Home/addda.js</File>
</Script>
</Scripts>
<Styles>
<style path= "~/content/themes/base/css" >
<File>~/Content/themes/base/jquery.ui.core.css</File>
<File>~/Content/themes/base/jquery.ui.resizable.css</File>
<File>~/Content/themes/base/jquery.ui.selectable.css</File>
<File>~/Content/themes/base/jquery.ui.accordion.css</File>

<File>~/Content/themes/base/jquery.ui.dialog.css</File>
<File>~/Content/themes/base/jquery.ui.slider.css</File>
<File>~/Content/themes/base/jquery.ui.tabs.css</File>

</Style>
<style path= "~/content/css" >
<File>~/Content/site.css</File>
</Style>
</Styles>
</root>

code file: BundleConfig.cs

Copy Code code as follows:

public class Bundleconfig
{
public static string Bundleconfigpath = "~/config/bundleconfig.xml";

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<string> files = getfilesformnode (node);
if (Files. Count > 0)
{
Bound. Include (Files. ToArray ());
Bundles. ADD (bound);
}
}
}
Regester Style
XmlNodeList stylelist = root. SelectNodes ("Styles/style");

}
}
}

Files. ADD (NodeFile.InnerText.Trim ());
}
return files;
}

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 ();
}
