Visual C++中宽字节与多字节字符互相转换的方法

多字节转宽字节

#include<Windows.h>

wchar_t* MultiCharToWideChar(char* str)
{
    auto len = MultiByteToWideChar(CP_ACP, 0, str, strlen(str), NULL, 0);
    wchar_t *buffer = new wchar_t[len + 1];
    MultiByteToWideChar(CP_ACP, 0, str, strlen(str), buffer, len);
    buffer[len] = '\0';
    return buffer;
}

 

宽字节转多字节

 

#include<Windows.h>

char* WideCharToMultiChar(TCHAR* str)
{
    auto len = WideCharToMultiByte(CP_ACP, 0, str, lstrlen(str), NULL, 0, NULL, NULL);
    char *buffer = new char[len + 1];
    WideCharToMultiByte(CP_ACP, 0, str, lstrlen(str), buffer, len, NULL, NULL);
    buffer[len] = '\0';
    return buffer;
}
