C#搜索文件和文件夹，某些文件夹除外 [英] C# Searching for files and folders except in certain folders

问题描述

有没有办法使用 LINQ 命令从 SearchOption 中排除某些目录像这样

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

string path = "C:SomeFolder";

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

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

路径由 Sub1 和 Sub2 文件夹组成，其中包含某些文件.我需要从目录搜索中排除它们.

The path consists of Sub1 and Sub2 Folders with certain files in it. I need to exclude them from directory search.

谢谢

这有效:

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)));

这有助于异常

推荐答案

据我所知没有.但是您可以使用非常简单的 LINQ 在一行中完成此操作.

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();

您也可以轻松组合多个排除 DIR.

You can easily combine multiple exclude DIRs too.
