asp.net-mvc - asp.net mvc 从包中排除 css 文件

Question

我有这样的捆绑

bundles.Add(new StyleBundle("~/Content/themes/default/css")
       .IncludeDirectory("~/Content/themes/Default", "*.css"));

但我想从中排除一个 CSS 文件。

是否可以在不指定捆绑包中的每个 CSS 文件的情况下做到这一点？

Answer 1

尝试使用IgnoreList.Ignore；bundles.IgnoreList.Ignore(...).

扩展方法可能是您需要的：

public static class BundleExtentions
{
    public static Bundle IncludeDirectoryWithExclusion(this StyleBundle bundle, string directoryVirtualPath, string searchPattern, params string[] toExclude)
    {
        var folderPath = HttpContext.Current.Server.MapPath(directoryVirtualPath);

        foreach (var file in Directory.GetFiles(folderPath, searchPattern))
        {
            if (!String.IsNullOrEmpty(Array.Find(toExclude, s => s.ToLower() == file.ToLower())))
            {
                continue;
            }     

            bundle.IncludeFile(directoryVirtualPath + "/" + file);
        }

        return bundle;
}

然后用法应该是：

bundles.Add(new StyleBundle("~/Content/themes/default/css")
   .IncludeDirectoryWithExclusion("~/Content/themes/Default", "*.css", "file-you-dont-want.css"));

我目前不在 PC 上，因此上述内容未经测试，但应该为您提供解决方案的模板。

我已经改进了 Jon Malcolm 的好建议（以及 Satpal 的一些更新），以解决它所具有的一些缺点：

1) 它使用“.min”打破了捆绑包的默认行为。文件

2）它不允许搜索模式，但只能排除文件

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


public static class BundleExtentions
{
    public static Bundle IncludeDirectoryWithExclusion(this Bundle bundle, string directoryVirtualPath, string searchPattern, bool includeSubDirectories, params string[] excludePatterns)
    {
        string folderPath = HttpContext.Current.Server.MapPath(directoryVirtualPath);

        SearchOption searchOption = includeSubDirectories
                                        ? SearchOption.AllDirectories
                                        : SearchOption.TopDirectoryOnly;

        HashSet<string> excludedFiles = GetFilesToExclude(folderPath, searchOption, excludePatterns);
        IEnumerable<string> resultFiles = Directory.GetFiles(folderPath, searchPattern, searchOption)
                                                    .Where(file => !excludedFiles.Contains(file) && !file.Contains(".min."));

        foreach (string resultFile in resultFiles)
        {
            bundle.Include(directoryVirtualPath + resultFile.Replace(folderPath, "")
                    .Replace("\\", "/"));
        }

        return bundle;
    }

    private static HashSet<string> GetFilesToExclude(string path, SearchOption searchOptions, params string[] excludePatterns)
    {
        var result = new HashSet<string>();

        foreach (string pattern in excludePatterns)
        {
            result.UnionWith(Directory.GetFiles(path, pattern, searchOptions));
        }

        return result;
    }
}

我的一个示例用法是包含 lib 文件夹中以 angular 开头的所有库，但不包括所有语言环境脚本（因为稍后将根据语言在单独的包中添加一个）：

bundles.Add(new Bundle("~/bundles/scripts")
                .Include("~/wwwroot/lib/angular/angular.js") // Has to be first
                .IncludeDirectoryWithExclusion("~/wwwroot/lib", "*.js", true, "*.locale.*.js"));

如果您同时拥有 angular.min.js 和 angular.js 并在调试中添加未缩小的版本并在发行版中使用现有的 .min.js，这将正常运行。

这是另一个重载现有IncludeDirectory方法并支持搜索子目录的扩展方法。

public static class BundleExtensions
{
    public static Bundle IncludeDirectory(
        this Bundle bundle,
        string directoryVirtualPath,
        string searchPattern,
        params string[] filesToExclude)
    {
        return IncludeDirectory(bundle, directoryVirtualPath, searchPattern, false, filesToExclude);
    }
    public static Bundle IncludeDirectory(
        this Bundle bundle,
        string directoryVirtualPath,
        string searchPattern,
        bool searchSubdirectories,
        params string[] filesToExclude)
    {
        var physicalPath = HttpContext.Current.Server.MapPath(directoryVirtualPath);
        return bundle.Include(Directory
            .EnumerateFiles(physicalPath, searchPattern, searchSubdirectories ? SearchOption.AllDirectories : SearchOption.TopDirectoryOnly)
            .Select(physicalFileName => physicalFileName.Replace(physicalPath, directoryVirtualPath).Replace(Path.DirectorySeparatorChar, Path.AltDirectorySeparatorChar))
            .Where(virtualFileName => !filesToExclude.Contains(virtualFileName))
            .ToArray());
    }
}
