我想列出该目录的目录和子目录中包含的每个文件和目录。如果我选择C：\作为目录，程序将获得它可以访问的硬盘驱动器上的每个文件和文件夹的每个名称。
列表可能看起来像
fd\1.txt fd\2.txt fd\a\ fd\b\ fd\a\1.txt fd\a\2.txt fd\a\a\ fd\a\b\ fd\b\1.txt fd\b\2.txt fd\b\a fd\b\b fd\a\a\1.txt fd\a\a\a\ fd\a\b\1.txt fd\a\b\a fd\b\a\1.txt fd\b\a\a\ fd\b\b\1.txt fd\b\b\a

string[] allfiles = Directory.GetFiles("path/to/dir", "*.*", SearchOption.AllDirectories);
其中*.*是匹配文件的模式
如果还需要目录，您可以这样：
foreach (var file in allfiles){
FileInfo info = new FileInfo(file);
// Do something with the Folder or just add them to a list via nameoflist.add();
}

Directory.GetFileSystemEntries存在于.NET 4.0+中，并返回文件和目录。像这样称呼它：
string[] entries = Directory.GetFileSystemEntries(path, "*", SearchOption.AllDirectories);
请注意，它不会尝试列出您无法访问的子目录的内容（UnauthorizedAccessException），但它可能足以满足您的需求。

使用GetDirectories和GetFiles方法获取文件夹和文件。
使用SearchOption AllDirectories获取子文件夹中的文件夹和文件。

我担心，GetFiles方法会返回文件列表，但不返回目录。问题中的列表提示我结果应该包括文件夹。如果您想要更多自定义列表，可以尝试递归调用GetFiles和GetDirectories。试试这个：
List<string> AllFiles = new List<string>();
void ParsePath(string path)
{
string[] SubDirs = Directory.GetDirectories(path);
AllFiles.AddRange(SubDirs);
AllFiles.AddRange(Directory.GetFiles(path));
foreach (string subdir in SubDirs)
ParsePath(subdir);
}
提示：如果您需要检查任何特定属性，可以使用FileInfo和DirectoryInfo类。

你可以使用FindFirstFile返回一个句柄，然后递归调用一个调用FindNextFile的函数。这是一个很好的方法，因为引用的结构将填充各种数据，如alternativeName，lastTmeCreated，modified，attributes等
但是当你使用.net框架时，你必须进入非托管区域。

如果您无权访问目录树中的子文件夹，则Directory.GetFiles会停止并抛出异常，从而导致接收字符串[]中出现空值。
在这里，请看这个答案 https://stackoverflow.com/a/38959208/6310707
它管理循环内的异常并继续工作，直到遍历整个文件夹。

以下示例处理异常的目录树中的最快（非并行化）方式列表文件和子文件夹。使用DirectoryOption.DnumerateDirectories使用SearchOption.AllDirectories来枚举所有目录会更快，但如果遇到UnauthorizedAccessException或PathTooLongException，此方法将失败。
使用通用的Stack集合类型，它是后进先出（LIFO）堆栈，不使用递归。从https://msdn.microsoft.com/en-us/library/bb513869.aspx开始，允许您枚举所有子目录和文件，并有效处理这些异常。
