我想要列出指定目录及其子目录中包含的每个文件和目录的名称。如果我选择C:\作为目标目录，程序将获取硬盘上所有有访问权限的文件和文件夹的名称。
列表可能如下所示
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

“ReadDirectories”方法被调用，直到扫描完最后一个目录。
如果您无法访问目录树中的子文件夹，则Directory.GetFiles会停止并抛出异常，导致接收字符串数组中的空值。
在这里，看看这个答案https://dev59.com/bXVC5IYBdhLWcg3w1Exq#38959208
它在循环内部处理异常并继续工作，直到整个文件夹被遍历完毕。
使用此功能，您可以直接运行它们并在控制台运行时选择子文件夹

有点简单和慢，但是有效！ 如果您没有提供文件路径，基本上使用“fixPath”这只是一个例子....您可以搜索您想要的正确文件类型，我在选择列表名称时犯了一个错误，因为“temporaryFileList”是搜索的文件列表，所以继续进行....而“errorList”则不言自明
