擴充asp.net Bundle

前言

建立Asp.net  MVC4項目的時候,在Global.asax.cs裡面發現多了一句代碼

BundleConfig.RegisterBundles(BundleTable.Bundles)

google了以後終於弄清楚了這個的作用，發現這個東西確實非常實用，且功能強大，能夠壓縮合并js和CSS，但是目前的使用起來不是特別好，如果添加js或者css檔案的話，需要修改BundleConfig的代碼。

這裡我自己簡單修改了BundleConfig，對這個進行簡單的擴充。

下面貼出代碼：

先貼設定檔BundleConfig.xml(檔案放在網站目錄下路徑見代碼中變數BundleConfigPath)

<?xml version="1.0" encoding="utf-8" ?>
<root>
<Scripts>
<Script Path="~/bundles/jquery">
<File>~/Scripts/jquery-{version}.js</File>

<Script Path="~/bb/aa">

代碼檔案：BundleConfig.cs
