推荐答案

您也可以使用 FileInfo.DirectoryName 访问路径的目录部分[^ ] .

您可以访问 FileInfo.Directory [ DirectoryInfo.Name [ DirectoryInfo.Parent [

You may also use the System.IO.FileInfo[^] class. You can then access the directory part of the path using FileInfo.DirectoryName [^].

You can access the FileInfo.Directory[^] which returns a DriveInfo object - use the DirectoryInfo.Name[^] to get the name of the directory, then use DirectoryInfo.Parent[^] to access the parent directory. Repeat until you you have reached the root directory of the drive - i.e. Parent returns null.

使用Split并排除0和最后一个条目

Use Split and exclude the 0 and the last entry

string[] dirs = pathname.Split('\\');
//dirs[1] will contain hello etc
