Linq中的目录和子目录过滤器

Question

我需要列出路径中的所有目录.我只需要获取最后一个子目录路径而不是所有路径.

即为

pathbase/2016/01

我不需要pathbase/2016而是pathbase/2016/01

现在我正在使用此代码:

List<string> dirs = new List<string>(Directory.EnumerateDirectories(pathBase));
string[] entries = System.IO.Directory.GetDirectories(pathBase, "*", 
    SearchOption.AllDirectories);

var listDir = from dir
              in entries

return listDir.ToList();

我可以在Linq中使用哪种类型的过滤器来排除此目录？

谢谢.

Answer 1

你的意思是你需要所有leafs目录(没有子目录的目录)？

如果是这样,那就应该这样做

// First off, don't use GetDirectories on the static Directory class, it returns a string path and not a DirectoryInfo which isn't very usefull here, instead create a DirectoryInfo and go from there:

var RootDirectory = new DirectoryInfo(pathBase);
// Then queries all of it's subdirectories and filter on those
var listDir  = RootDirectory.GetDirectories("*",SearchOption.AllDirectories)
    .Where(dir=>!dir.GetDirectories().Any())
    .ToList();
