使用Unicode Files Path - C ++创建目录树 [英] Create directory tree with Unicode Files Path - C++

问题描述

我如何用unicode格式创建一个目录？

这样的东西：

Hi,
How can I create a directory with unicode format?
Something like this:

/*
The exists directory path is: "C:\A\B\"
I would create the folderName path ("C:\A\B\C\D\") if not exists.
*/
wchar_t* folderName = L"C:\A\B\C\D\";
bool result = createFolder(folderName);

...

bool createFolder(wchar_t* _folderName)
{
//Return TRUE, if already exists or create is successful
}

Thx，

推荐答案

请参考吹码。

Hi,
please refer to the blow code.

#include "stdafx.h"
#include <windows.h>


void CreateDirectoryWithChecking(const wchar_t* i_LPSTR_FolderPath)
{
	::WIN32_FIND_DATA data;
	::HANDLE handle = ::FindFirstFile(i_LPSTR_FolderPath, &data);
	if (handle == INVALID_HANDLE_VALUE)
		::CreateDirectory(i_LPSTR_FolderPath, NULL);
	else
		FindClose(handle);
}


bool createFolderStrecture(const wchar_t* _folderName)
{
	if (!_folderName)return false;

	size_t len = 0;
	while (_folderName[len] != '\0')++len;
	

	for (size_t index = 0; index < len; index++)
	{
		if (_folderName[index] =='\\' && index>3)
		{
			wchar_t curFolderPath[_MAX_PATH] = { 0 };
			::memcpy_s(curFolderPath, _MAX_PATH*sizeof(wchar_t), _folderName, (index)*sizeof(wchar_t));
			CreateDirectoryWithChecking(curFolderPath);
		}
	}

	return true;	
}

int _tmain(int argc, _TCHAR* argv[])
{
	wchar_t* folderName = L"F:\\A\\B\\C\\D\\";
	bool result = createFolderStrecture(folderName);

	return 0;
}

谢谢nvtkrishna！



很棒！

我做了一些更改（参见粗体文字），因为我的构建器没有编译它。

但重点是你的！

你认为这没关系？



问候，

Thanks nvtkrishna!

It is great!
I have made some changes (see bold text), because my builder do not compiled it.
But the point is Yours!
You think this is okay?
