c++ socket flex 中文 乱码

c++ gsoap c# webservice 中文 乱码

这两种乱码都是c++与其他语言socket通讯时乱码的错误，解决的关键代码：

//UTF8转成Unicode
wchar_t * Ansi22Utf8::UTF8ToUnicode( const char* str )
{
      int    textlen = 0;
      wchar_t * result;
      textlen = MultiByteToWideChar( CP_UTF8, 0, str,-1,    NULL,0 );  
      result = (wchar_t *)malloc((textlen+1)*sizeof(wchar_t));  
      memset(result,0,(textlen+1)*sizeof(wchar_t));  
      MultiByteToWideChar(CP_UTF8, 0,str,-1,(LPWSTR)result,textlen );  
      return    result;  
}

//Unicode转成ANSI
char * Ansi22Utf8::UnicodeToANSI( const wchar_t *str )
{
      char * result;
      int textlen = 0;
      // wide char to multi char
      textlen = WideCharToMultiByte( CP_ACP,    0,    str,    -1,    NULL, 0, NULL, NULL );
      result =(char *)malloc((textlen+1)*sizeof(char));
      memset( result, 0, sizeof(char) * ( textlen + 1 ) );
      WideCharToMultiByte( CP_ACP, 0, str, -1, result, textlen, NULL, NULL );
      return result;
}
