我正在创建一个 FileFinder 类，您可以在其中进行如下搜索：

    var fileFinder = new FileFinder(
                         new string[]
                             {
                                  "C:\\MyFolder1",
                                  "C:\\MyFolder2" 
                             }, 
                         new string[]
                             {
                                  "*.txt",
                                  "*.doc"
                             } );
    fileFinder.FileFound += new EventHandler<FileFinderEventArgs>(FileFinder_FileFound);
    DoSearch();

如果我执行该代码，则每次 *.txt 或 时都会调用 FileFinder_FileFound在 C:\\MyFolder1 及其子文件夹或 C:\\MyFolder2 及其子文件夹中找到 *.doc 文件。

因此，该类会查看子文件夹，但我也希望它能够查看它遇到的任何 zip 文件，就像它们是文件夹一样。我该怎么做？最好不要创建临时文件...

编辑忘记提及这不是个人项目；它用于我正在与我的公司合作的商业应用程序。

I am creating a FileFinder class, where you can do a search like this:

    var fileFinder = new FileFinder(
                         new string[]
                             {
                                  "C:\\MyFolder1",
                                  "C:\\MyFolder2" 
                             }, 
                         new string[]
                             {
                                  "*.txt",
                                  "*.doc"
                             } );
    fileFinder.FileFound += new EventHandler<FileFinderEventArgs>(FileFinder_FileFound);
    DoSearch();

If I executed that code, FileFinder_FileFound would be called every time a *.txt or *.doc file was found in C:\\MyFolder1 and its subfolders, or C:\\MyFolder2 and its subfolders.

Sot the class looks through subfolders, but I also want it to look through any zip files it comes across, as if they were folders. How can I do this? It would be preferable that no temporary files be created...

EDIT Forgot to mention this is not a personal project; its for a commercial application I'm working on with my company.

如果您可以使用 .NET 4.5 或更高版本，那么您现在终于可以使用 ZipArchive。它位于 System.IO.Compression 命名空间中。该示例也使用了 ZipFile 类，它不仅需要引用 System.IO.Compression 程序集，还需要引用 System.IO.Compression.FileSystem 程序集（两者都贡献于相同的名称空间）。
MSDN： http:// /msdn.microsoft.com/en-us/library/system.io.compression.ziparchive%28v=vs.110%29.aspx

因此，如果您的查找器遇到 zip 文件，您可以执行以下操作（其要点）：

using System;
using System.IO;
using System.IO.Compression;

using (ZipArchive archive = ZipFile.OpenRead(zipFilePath))
{
    foreach (ZipArchiveEntry entry in archive.Entries)
    {
        if (entry.FullName.EndsWith(".txt", StringComparison.OrdinalIgnoreCase) ||
            entry.FullName.EndsWith(".doc", StringComparison.OrdinalIgnoreCase))
        {
            // FileFinder_FileFound(new FileFinderEventArgs(...))
        }
    }
}

If you can use .NET 4.5 or higher you can now finally use ZipArchive. It's in the System.IO.Compression namespace. The example uses ZipFile class too, which requires not just referencing System.IO.Compression assembly, but System.IO.Compression.FileSystem assembly too (both contribute to the same namespace).
MSDN: http://msdn.microsoft.com/en-us/library/system.io.compression.ziparchive%28v=vs.110%29.aspx

So if your finder encounter a zip file, you can do something like this (the gist of it):

using System;
using System.IO;
using System.IO.Compression;

using (ZipArchive archive = ZipFile.OpenRead(zipFilePath))
{
    foreach (ZipArchiveEntry entry in archive.Entries)
    {
        if (entry.FullName.EndsWith(".txt", StringComparison.OrdinalIgnoreCase) ||
            entry.FullName.EndsWith(".doc", StringComparison.OrdinalIgnoreCase))
        {
            // FileFinder_FileFound(new FileFinderEventArgs(...))
        }
    }
}
