Question

希望有人可以在这里为我提供帮助，我对使用目录不是很熟悉。我的应用程序压缩文件并将其存储在媒体目录中，以及将它们存储在数据库中。如果我创建目录并实际分别调用每个文件，则此方法效果很好。

但是我想使其动态化，并处理install文件夹下的所有文件夹，对于该目录下的每个目录，我想处理该目录下的每个目录和所有文件。

我尝试过的事情：

public class SetupFiles : ISetupFiles
{
    private readonly ISession _session;
    private readonly IFileService _fileService;
    private readonly IFileProvider _fileProvider;

    public SetupFiles(ISession session, IFileService fileService, IFileProvider fileProvider)
    {
        _session = session;
        _fileService = fileService;
        _fileProvider = fileProvider;
    }
public void Setup()
    {
        string installPath = ("install/images/");
        _session.Transact(session =>
        {

            DirectoryInfo dir = new DirectoryInfo(installPath);
            DirectoryInfo[] subdirectories = dir.GetDirectories();
            foreach (var subdirectory in subdirectories)
            {
                string currentDirName = Directory.GetCurrentDirectory();
                var directory = new MediaCategory
                {
                    Name = subdirectory.Name.ToString().ToUpper(),
                    UrlSegment = subdirectory.Name.Trim().ToLower(),
                };
                session.Save(directory);

                string[] pngFiles = Directory.GetFiles(currentDirName, "*.png", SearchOption.AllDirectories);
                string[] jpgFiles = Directory.GetFiles(currentDirName, "*.jpg", SearchOption.AllDirectories);
                string[] gifFiles = Directory.GetFiles(currentDirName, "*.gif", SearchOption.AllDirectories);
                string[] pdfFiles = Directory.GetFiles(currentDirName, "*.pdf", SearchOption.AllDirectories);

                foreach (var currentPngFile in pngFiles)
                {
                    var fileStream = _fileProvider.GetFileInfo(currentPngFile).CreateReadStream();
                    MediaFile dbpngFile = _fileService.AddFile(fileStream, Path.GetFileName(currentPngFile), "image/png", fileStream.Length, directory);
                }
                foreach (var currentJpgFile in jpgFiles)
                {
                    var fileStream = _fileProvider.GetFileInfo(currentJpgFile).CreateReadStream();
                    MediaFile dbjpgFile = _fileService.AddFile(fileStream, Path.GetFileName(currentJpgFile), "image/jpg", fileStream.Length, directory);
                }
                foreach (var currentGifFile in gifFiles)
                {
                    var fileStream = _fileProvider.GetFileInfo(currentGifFile).CreateReadStream();
                    MediaFile dbgifFile = _fileService.AddFile(fileStream, Path.GetFileName(currentGifFile), "image/gif", fileStream.Length, directory);
                }
                foreach (var currentPdfFile in pdfFiles)
                {
                    var fileStream = _fileProvider.GetFileInfo(currentPdfFile).CreateReadStream();
                    MediaFile dbgifFile = _fileService.AddFile(fileStream, Path.GetFileName(currentPdfFile), "file/pdf", fileStream.Length, directory);

                }
            }

        });
    }

但是由于某种原因，我收到一个错误，它找不到目录。

任何帮助将不胜感激。

int行DirectoryInfo[] subdirectories = dir.GetDirectories();的目录显示目录，但是GetDirectories()返回NULL。

我一定有脑筋。大声笑在@ ciubotariu-florin的帮助下，我得以解决了这个问题。对于其他遇到此问题的人，wwwroot是一个环境文件夹，并且是IIS config中Web root的一部分。因此，要与Directory()和/或DirectoryInfo()一起使用，必须使用IHostingEnvironment，这样才能使用IHostingEnvironment.WebRootPath，以便更改我的路径

string installPath = ("install/images/");

到

string installPath = Path.Combine(_env.WebRootPath, "install/images/").ToLower();

解决了我的问题。
