//这是我在 Winform 用递归的方式去读取指定路径下的全部文件/文件夹:
FileSystemInfo[] files = directory.GetFileSystemInfos();
//我见很多人都是这样子:
// 取得指定路径下所有符合条件的文件
string[] strFiles = Directory.GetFiles(strDir, strFilePattern);
// 取得指定路径下所有目录
string[] strDirs = Directory.GetDirectories(strDir);
//我不用别人的这种方式可以么,因为这种方式不是要遍历"两次"分别获的 "File" 和 "Directory"么...
但是当我用:
FileSystemInfo[] files = directory.GetFileSystemInfos();
去试图访问的时候,发现有些文件夹不可访问...
