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;  }
