如何遍历目录? [英] How do I traverse into directories?

问题描述

如果我有一个包含 5 个子文件夹的文件夹，并且我想在每个子文件夹中搜索某些文件(我的程序存在于主文件夹中).如何让我的程序在 C++ 中进出这些文件夹?

If I have a folder that has, say, 5 sub-folders, and I want to search for certain files inside each sub-folder(my program is present inside the main folder). How do I make my program traverse into and out of those folders in C++?

我需要我的程序在 Windows 平台上运行.

推荐答案

只需使用 boost 的 recursive_directory_iterator，并过滤你想要的文件/目录.

Just use boost's recursive_directory_iterator, and filter the files/directory you want.

boost::filesystem::recursive_directory_iterator iter("your\path");
boost::filesystem::recursive_directory_iterator end;
for (; iter != end; ++iter) {
    // check for things like is_directory(iter->status()), iter->filename() ....
    // optionally, you can call iter->no_push() if you don't want to
    // enter a directory
    // see all the possibilities by reading the docs.
}
