如何在Windows-PC上用c ++复制非空目录？ [英] How could I copy a non-empty directory with c++ on windows-PC?

问题描述

各位大家好！为此我有一个严重的问题，几个月前我已经写了一个文件复制非空目录给另一个，包括它的所有子文件。但这个函数是Recursive.anyone有更好的方法来解决这个功能？如果只是不使用递归！非常感谢！我将不胜感激，伙计们！

推荐答案

也许这段代码适合你：

Maybe this code will work for you:

bool CopyNonEmptyFolder(const std::wstring& source_folder, const std::wstring& target_folder)
{
	std::wstring new_sf = source_folder + L"\\*";
	WCHAR sf[MAX_PATH + 1];
	WCHAR tf[MAX_PATH + 1];

	wcscpy_s(sf, MAX_PATH, new_sf.c_str());
	wcscpy_s(tf, MAX_PATH, target_folder.c_str());

	sf[lstrlenW(sf) + 1] = 0;
	tf[lstrlenW(tf) + 1] = 0;

	SHFILEOPSTRUCTW s = { 0 };
	s.wFunc = FO_COPY;
	s.pTo = tf;
	s.pFrom = sf;
	s.fFlags = FOF_SILENT | FOF_NOCONFIRMMKDIR | FOF_NOCONFIRMATION | FOF_NOERRORUI | FOF_NO_UI;
	int res = SHFileOperationW(&s);

	return res == 0;
}
