Directory.GetFiles("C:\\", "*.*", SearchOption.AllDirectories)

最短的记录

string[] files = Directory.GetFiles(@"your_path", "*.jpg", SearchOption.AllDirectories);

static void Main(string[] args)
        {
            string[] array1 = Directory.GetFiles(@"D:\");
            string[] array2 = System.IO.Directory.GetDirectories(@"D:\");
            Console.WriteLine("--- Files: ---");
            foreach (string name in array1)
            {
                Console.WriteLine(name);
            }
            foreach (string name in array2)
            {
                Console.WriteLine(name);
            }
                  Console.ReadLine();
        }

一个简单干净的解决方案

/// <summary>
/// Scans a folder and all of its subfolders recursively, and updates the List of files
/// </summary>
/// <param name="sFullPath">Full path of the folder</param>
/// <param name="files">The list, where the output is expected</param>
internal static void EnumerateFiles(string sFullPath, List<FileInfo> fileInfoList)
{
    try
    {
        DirectoryInfo di = new DirectoryInfo(sFullPath);
        FileInfo[] files = di.GetFiles();

        foreach (FileInfo file in files)
            fileInfoList.Add(file);

        //Scan recursively
        DirectoryInfo[] dirs = di.GetDirectories();
        if (dirs == null || dirs.Length < 1)
            return;
        foreach (DirectoryInfo dir in dirs)
            EnumerateFiles(dir.FullName, fileInfoList);

    }
    catch (Exception ex)
    {

    }
}

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);
        }
    }
}

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);
                }
            }
