    public enum EntryType
    {
        Directory = 0,
        File = 1
    }

方法:

 static DirOrFileModel DirSearch(DirOrFileModel startDir)
        {
            var currentDir = startDir;
            try
            {
                foreach (string d in Directory.GetDirectories(currentDir.Location))
                {

                    {
                        EntryType = EntryType.Directory,

                    };
                    currentDir.Entries.Add(newDir);

                    DirSearch(newDir);
                }

                foreach (string f in Directory.GetFiles(currentDir.Location))
                {
                    var newFile = new DirOrFileModel
                    {
                        EntryType = EntryType.File,
                        Location = f,
                        Name = Path.GetFileNameWithoutExtension(f)
                    };
                    currentDir.Entries.Add(newFile);
                }

            }
            catch (Exception excpt)
            {
                Console.WriteLine(excpt.Message);
            }
            return startDir;
        }

用法:

var dir = new DirOrFileModel
            {
                Name = "C",
                Location = @"C:\",
                EntryType = EntryType.Directory
            };

            dir = DirSearch(dir);

这一个帮助我得到一个目录和子目录中的所有文件，可能对某人有帮助。[灵感来自上述答案]

static void Main(string[] args)
    {
        try
        {
            var root = @"G:\logs";
            DirectorySearch(root);
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
        Console.ReadKey();
    }





public static void DirectorySearch(string root, bool isRootItrated = false)
{
    if (!isRootItrated)
    {
        var rootDirectoryFiles = Directory.GetFiles(root);
        foreach (var file in rootDirectoryFiles)
        {
            Console.WriteLine(file);
        } 
    }

    var subDirectories = Directory.GetDirectories(root);
    if (subDirectories?.Any() == true)
    {
        foreach (var directory in subDirectories)
        {
            var files = Directory.GetFiles(directory);
            foreach (var file in files)
            {
                Console.WriteLine(file);
            }
            DirectorySearch(directory, true);
        }
    }
}

我更喜欢使用DirectoryInfo，因为我可以得到FileInfo的，而不仅仅是字符串。

        string baseFolder = @"C:\temp";
        DirectoryInfo di = new DirectoryInfo(baseFolder);

        string searchPattern = "*.xml";

        ICollection<FileInfo> matchingFileInfos = di.GetFiles(searchPattern, SearchOption.AllDirectories)
            .Select(x => x)
            .ToList();

我这样做的情况下，在未来我需要未来过滤..基于FileInfo的属性。

        string baseFolder = @"C:\temp";
        DirectoryInfo di = new DirectoryInfo(baseFolder);

        string searchPattern = "*.xml";

        ICollection<FileInfo> matchingFileInfos = di.GetFiles(searchPattern, SearchOption.AllDirectories)
            .Where(x => x.LastWriteTimeUtc < DateTimeOffset.Now)
            .Select(x => x)
            .ToList();

如果需要，我也可以求助于字符串。(仍然是未来证明过滤器/where-clause子句的东西。

        string baseFolder = @"C:\temp";
        DirectoryInfo di = new DirectoryInfo(baseFolder);

        string searchPattern = "*.xml";

        ICollection<string> matchingFileNames = di.GetFiles(searchPattern, SearchOption.AllDirectories)
            .Select(x => x.FullName)
            .ToList();

请注意，如果您想通过扩展文件，“.”是一个有效的搜索模式。

至少在。net 4.5中，有这样一个版本，它要短得多，并且有额外的好处，可以评估包含在列表中的任何文件标准:

public static IEnumerable<string> GetAllFiles(string path, 
                                              Func<FileInfo, bool> checkFile = null)
{
    string mask = Path.GetFileName(path);
    if (string.IsNullOrEmpty(mask)) mask = "*.*";
    path = Path.GetDirectoryName(path);
    string[] files = Directory.GetFiles(path, mask, SearchOption.AllDirectories);

    foreach (string file in files)
    {
        if (checkFile == null || checkFile(new FileInfo(file)))
            yield return file;
    }
}

像这样使用:

var list = GetAllFiles(mask, (info) => Path.GetExtension(info.Name) == ".html").ToList();

这篇文章涵盖了您需要的所有内容。除了与搜索文件和比较名称不同，只需打印出名称。

可以这样修改:

static void DirSearch(string sDir)
{
    try
    {
        foreach (string d in Directory.GetDirectories(sDir))
        {
            foreach (string f in Directory.GetFiles(d))
            {
                Console.WriteLine(f);
            }
            DirSearch(d);
        }
    }
    catch (System.Exception excpt)
    {
        Console.WriteLine(excpt.Message);
    }
}

GONeale提到上面没有列出当前目录中的文件，并建议将文件列表部分放在获取目录的部分之外。下面的代码可以做到这一点。它还包括一个Writeline行，你可以取消注释，这有助于跟踪你在递归中的位置，这可能有助于显示调用，帮助显示递归是如何工作的。

            DirSearch_ex3("c:\\aaa");
            static void DirSearch_ex3(string sDir)
            {
                //Console.WriteLine("DirSearch..(" + sDir + ")");
                try
                {
                    Console.WriteLine(sDir);

                    foreach (string f in Directory.GetFiles(sDir))
                    {
                        Console.WriteLine(f);
                    }

                    foreach (string d in Directory.GetDirectories(sDir))
                    {
                        DirSearch_ex3(d);
                    }
                }
                catch (System.Exception excpt)
                {
                    Console.WriteLine(excpt.Message);
                }
