Unicode 和 Ansi转换方法——wchar_t*、char*

1、单字节转宽字节（char* --> wchar_t*）

/*
**将单字节char*转化为宽字节wchar_t*  
*/
inline wchar_t* AnsiToUnicode( const char* szStr )  
{  
    int nLen = MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, szStr, -1, NULL, 0 );  
    if (nLen == 0)  
    {  
        return NULL;  
    }  
    wchar_t* pResult = new wchar_t[nLen];  
    MultiByteToWideChar( CP_ACP, MB_PRECOMPOSED, szStr, -1, pResult, nLen );  
    return pResult;  
}  

2、宽字节转单字节（wchar_t* --> char*）

/***将宽字节wchar_t*转化为单字节char*  */inline char* UnicodeToAnsi( const wchar_t* szStr )  {      int nLen = WideCharToMultiByte( CP_ACP, 0, szStr, -1, NULL, 0, NULL, NULL );      if (nLen == 0)      {          return NULL;      }      char* pResult = new char[nLen];      WideCharToMultiByte( CP_ACP, 0, szStr, -1, pResult, nLen, NULL, NULL );      return pResult;  }
