我需要以递归方式从目录及其子目录中获取所有文件,但不包括多个目录。我知道他们的名字。是否可以使用boost :: filesystem :: recursive_directory_iterator?

是的,在遍历目录时,您可以测试排除列表中的名称并使用递归迭代器的no_push()
成员来阻止它进入这样的目录,例如:
void selective_search( const path &search_here, const std::string &exclude_this_directory)
{
using namespace boost::filesystem;
recursive_directory_iterator dir( search_here), end;
while (dir != end)
{
// make sure we don't recurse into certain directories
// note: maybe check for is_directory() here as well...
if (dir->path().filename() == exclude_this_directory)
{
dir.no_push(); // don't recurse into this directory.
}
// do other stuff here.
++dir;
}
}
