更新：不确定是否重要，但我使用的是 MVC 5.2.3 和 Visual Studio 2015，问题有点老了。
但是，我制作了可以在 _viewStart.cshtml 中使用的动态捆绑。我所做的是创建了一个帮助类，将捆绑包存储在捆绑包字典中。然后在应用程序启动时，我从字典中提取它们并注册它们。我制作了一个静态布尔“bundlesInitialzed”，这样捆绑包只会添加到字典中一次。
示例助手：
public static class KBApplicationCore: .....
{
private static Dictionary<string, Bundle> _bundleDictionary = new Dictionary<string, Bundle>();
public static bool BundlesFinalized { get { return _BundlesFinalized; } }
/// <summary>
/// Add a bundle to the bundle dictionary
/// </summary>
/// <param name="bundle"></param>
/// <returns></returns>
public static bool RegisterBundle(Bundle bundle)
{
if (bundle == null)
throw new ArgumentNullException("bundle");
if (_BundlesFinalized)
throw new InvalidOperationException("The bundles have been finalized and frozen, you can only finalize the bundles once as an app pool recycle is needed to change the bundles afterwards!");
if (_bundleDictionary.ContainsKey(bundle.Path))
return false;
_bundleDictionary.Add(bundle.Path, bundle);
return true;
}
/// <summary>
/// Finalize the bundles, which commits them to the BundleTable.Bundles collection, respects the web.config's debug setting for optimizations
/// </summary>
public static void FinalizeBundles()
{
FinalizeBundles(null);
}
/// <summary>
/// Finalize the bundles, which commits them to the BundleTable.Bundles collection
/// </summary>
/// <param name="forceMinimize">Null = Respect web.config debug setting, True force minification regardless of web.config, False force no minification regardless of web.config</param>
public static void FinalizeBundles(bool? forceMinimize)
{
var bundles = BundleTable.Bundles;
foreach (var bundle in _bundleDictionary.Values)
{
bundles.Add(bundle);
}
if (forceMinimize != null)
BundleTable.EnableOptimizations = forceMinimize.Value;
_BundlesFinalized = true;
}
}
示例_ViewStart.cshtml
@{
var bundles = BundleTable.Bundles;
var baseUrl = string.Concat("~/App_Plugins/", KBApplicationCore.PackageManifest.FolderName, "/");
//Maybe there is a better way to do this, the goal is to make the bundle configurable without having to recompile the code
if (!KBApplicationCore.BundlesFinalized)
{
//Note, you need to reset the application pool in order for any changes here to be reloaded as the BundlesFinalized property is a static field that will only reset to false when the app restarts.
Bundle mainScripts = new ScriptBundle("~/bundles/scripts/main.js");
mainScripts.Include(new string[] {
baseUrl + "Assets/lib/jquery/jquery.js",
baseUrl + "Assets/lib/jquery/plugins/jqcloud/jqcloud.js",
baseUrl + "Assets/lib/bootstrap/js/bootstrap.js",
baseUrl + "Assets/lib/bootstrap/plugins/treeview/bootstrap-treeview.js",
baseUrl + "Assets/lib/angular/angular.js",
baseUrl + "Assets/lib/ckEditor/ckEditor.js"
});
KBApplicationCore.RegisterBundle(mainScripts);
Bundle appScripts = new ScriptBundle("~/bundles/scripts/app.js");
appScripts.Include(new string[] {
baseUrl + "Assets/app/app.js",
baseUrl + "Assets/app/services/*.js",
baseUrl + "Assets/app/directives/*.js",
baseUrl + "Assets/app/controllers/*.js"
});
KBApplicationCore.RegisterBundle(appScripts);
Bundle mainStyles = new StyleBundle("~/bundles/styles/main.css");
mainStyles.Include(new string[] {
baseUrl + "Assets/lib/bootstrap/build/less/bootstrap.less",
baseUrl + "Assets/lib/bootstrap/plugins/treeview/bootstrap-treeview.css",
baseUrl + "Assets/lib/ckeditor/contents.css",
baseUrl + "Assets/lib/font-awesome/less/font-awesome.less",
baseUrl + "Assets/styles/tlckb.less"
});
mainStyles.Transforms.Add(new BundleTransformer.Core.Transformers.CssTransformer());
mainStyles.Transforms.Add(new CssMinify());
mainStyles.Orderer = new BundleTransformer.Core.Orderers.NullOrderer();
KBApplicationCore.RegisterBundle(mainStyles);
KBApplicationCore.FinalizeBundles(true); //true = Force Optimizations, false = Force non Optmizations, null = respect web.config which is the same as calling the parameterless constructor.
}
}
注意：这应该更新为使用线程锁定来防止 2 个请求在第一个退出之前进入捆绑代码。
这种工作方式是在应用程序池重置后对站点的第一个请求运行视图启动。它调用助手上的 RegisterBundle，并按照调用 RegisterBundles 的顺序将 ScriptBundle 或 StyleBundle 传递给字典。
当 FinalizeBundles 被调用时，您可以指定 True 将强制优化而不管 web.config 调试设置，或者将其保留为 null 或使用不带该参数的构造函数以使其尊重 web.config 设置。传递 false 将强制它不使用优化，即使 debug 为 true。 FinalizeBundles 在 bundles 表中注册 bundles 并将 _BundlesFinalized 设置为 true。
一旦完成，再次调用 RegisterBundle 的尝试将引发异常，此时它被冻结。
此设置允许您添加新捆绑包以查看启动并重置应用程序池以使其生效。我写这篇文章的最初目的是因为我正在制作其他人会使用的东西，所以我希望他们能够完全改变前端 UI，而无需重建源代码来更改包。
