递归列出目录内容 [英] List content of directory recursively

问题描述

我需要代码来从驱动器中获取目录的所有文件(包括所有子目录)并将其存储到数组中.稍后，我想使用该数组并搜索特定文件并删除该文件.

提前谢谢.

I need code to get all the files of a directory (including all subdirectories) from a drive and store it into an array. At a later time I want to use that array and search for particular file and delete that file.

Thanks in advance.

推荐答案

使用类Directory(不是 DirectoryInfo )，使用带有SearchOption参数的方法GetFiles:AllDirectories用于递归目录搜索，TopDirectoryOnly仅用于一个目录.

Use the class Directory (not DirectoryInfo), the method GetFiles with SearchOption parameter: AllDirectories for recursive directory search, TopDirectoryOnly for just one directory.

此页面应满足您的需求.它们显示了一个函数的代码，该函数以递归方式列出目录和所有子目录中的所有文件:

This page should cater to your needs. They show code for a function that recursively lists all files in directory and all sub directories:

They return a List, but you can turn that into an array with the List.ToArray() method. I would not do that though because it''s so easy to search in a List using the Predicate delegate. Look that up on MSDN: List.Find & List.FindAll


Please refer to SAKryukov''s answer, it is the best solution in this case as it relies solely on already built in .NET functions plus you get your files in an array as per your request (or requirement).
If you already looked up List.Find and List.FindAll and would like to use it, you can create a list from an array and then back again should the need arise:

List<String> myList = new List<String>(theArrayFromTheGetFilesCall);

希望对您有帮助！
