VC 中char 与 wchar

char 转wchar_t

wchar_t* CharToWchar(char* c) {     int len = MultiByteToWideChar(CP_ACP, 0, c, strlen(c), NULL, 0);     wchar_t* m_wchar = new wchar_t[len + 1];     MultiByteToWideChar(CP_ACP, 0, c, strlen(c), m_wchar, len);     m_wchar[len] = '\0';     return m_wchar; }

返回结果用完要free掉.

调用：

char cstr[]="i am char string";

wchar_t *wcstr=CharToWchar(cstr);

wchar_t转char

char* WcharToChar(wchar_t* wc) {     int len = WideCharToMultiByte(CP_ACP, 0, wc, wcslen(wc), NULL, 0, NULL, NULL);     char *m_char = new char[len + 1];     WideCharToMultiByte(CP_ACP, 0, wc, wcslen(wc), m_char, len, NULL, NULL);     m_char[len] = '\0';     return m_char;

}

返回结果用完要free掉.

调用：

wchar_t wcstr[]=_L("i am char string");

char *cstr=WcharToChar(wcstr);
