我需要递归地从目录及其子目录中获取所有文件,但不包括几个目录。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no_push()递归迭代器的成员来防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;
    }
 }
