VC++ 复制整个文件夹

CopyFile只能复制一个文件，要想复制整个文件夹的所有文件，需要遍历文件夹里面的文件。

MyFile.h

#pragma once
#include <string>
#include <Windows.h>
#include <iostream>
#include <stdio.h>
#include <io.h>
#include <string>
#include <Shlwapi.h>
using namespace std;
class CMyFile
{
public:
	explicit CMyFile(void);
	~CMyFile(void);
    static void MyCopyFile(string sourceFilePath,string destFilePath);
};

 MyFile.cpp

#include "StdAfx.h"
#include "MyFile.h"

void CMyFile::MyCopyFile(string sourceFilePath,string destFilePath)

LPCWSTR StringToLPCWSTR(string orig)
{
	size_t origsize = orig.length() + 1;
	const size_t newsize = 100;
	size_t convertedChars = 0;
	wchar_t *wcstring = (wchar_t *)malloc(sizeof(wchar_t)*(orig.length()-1));
	mbstowcs_s(&convertedChars, wcstring, origsize, orig.c_str(), _TRUNCATE);

CMyFile::MyCopyFile("E:\\Test1","E:\\T2");
