wchar_t*转换string

场景

wchar[]转换string

实现代码

#include "stdafx.h"
#include <iostream>
#include <windows.h>
#include <string>
 
// wchar_t to string
void Wchar_tToString(std::string& szDst, wchar_t *wchar)
{
    wchar_t * wText = wchar;
    DWORD dwNum = WideCharToMultiByte(CP_OEMCP,NULL,wText,-1,NULL,0,NULL,FALSE);// WideCharToMultiByte的运用
    char *psText; // psText为char*的临时数组，作为赋值给std::string的中间变量
    psText = new char[dwNum];
    WideCharToMultiByte (CP_OEMCP,NULL,wText,-1,psText,dwNum,NULL,FALSE);// WideCharToMultiByte的再次运用
    szDst = psText;// std::string赋值
    delete []psText;// psText的清除
}

调用

	// 存放当前程序运行路径
	WCHAR SelfFile[MAX_PATH];
	//获取当前进程路径
	GetModuleFileName(NULL, SelfFile, MAX_PATH);
    // 当前程序存放路径
	string Current_Path;
	Wchar_tToString(Current_Path,SelfFile);
