有没有什么办法来排除SearchOption使用LINQ命令这样某些目录

Is there any way to exclude certain directories from SearchOption using LINQ command like this

var s1 = Directory.GetFiles(path , "*.*", SearchOption.AllDirectories);

var s2 = Directory.GetDirectories(path , "*.*", SearchOption.AllDirectories);

这工作：

string[] exceptions = new string[] { "c:\\SomeFolder\\sub1",
"c:\\SomeFolder\\sub2" };

var s1 = Directory.GetFiles("c:\\x86", "*.*",
SearchOption.AllDirectories).Where(d => exceptions.All(e =>
!d.StartsWith(e)));

推荐答案

没有没有，据我所知。但是你可以用很简单的LINQ做，在一个单行。

No there isn't as far as I know. But you could use very simple LINQ to do that in a single line.

var s1 = Directory.GetFiles(path , "*.*", SearchOption.AllDirectories).Where(d => !d.StartsWith("<EXCLUDE_DIR_PATH>")).ToArray();

您可以轻松地将多个排除目录了。

You can easily combine multiple exclude DIRs too.
