在Bonjour 1.0中调用GetAddrInfo（…）时的主机名是什么

我使用Bonjour 1.0 （.NET）通过本地家庭网络扫描regtype = "_http._tcp" ：

  DNSSDService service = new DNSSDService(); DNSSDEventManager eventManager = new DNSSDEventManager(); eventManager.ServiceFound += new _IDNSSDEvents_ServiceFoundEventHandler(eventManager_ServiceFound); DNSSDService browse = service.Browse(0, 0, "_http._tcp", null, eventManager); 

当我找到该服务的方法时： static void eventManager_ServiceFound(DNSSDService browser, DNSSDFlags flags, uint ifIndex, string serviceName, string regtype, string domain) 。

然后在该方法中我想使用方法： DNSSDService GetAddrInfo(DNSSDFlags glags, uint ifIndex, DNSSDAddressFamily addressFamily, string hostname , DNSSDEventManager eventManager)来了解服务的ip地址和端口。

问题是，我不知道应该是什么string hostname ，因此我没有得到任何结果：**请看看：???这里有什么？ 在代码中**

  static void eventManager_ServiceFound(DNSSDService browser, DNSSDFlags flags, uint ifIndex, string serviceName, string regtype, string domain) { Console.WriteLine("browser: " + browser + "\nDNSSDFlags " + flags+ "\nifIndex " + ifIndex +"\nserviceName: " + serviceName + "\nregtype: " +regtype+ "\ndomain: "+ domain); DNSSDEventManager eventManager = new DNSSDEventManager(); eventManager.AddressFound += new _IDNSSDEvents_AddressFoundEventHandler(eventManager_AddressFound); DNSSDAddressFamily family = new DNSSDAddressFamily(); browser.GetAddrInfo(flags, ifIndex, family, ???WHAT HERE???, eventManager); } private static void eventManager_AddressFound(DNSSDService service, DNSSDFlags flags, uint ifIndex, string hostname, DNSSDAddressFamily addressFamily, string address, uint ttl) { Console.WriteLine("----------------------------------------"); Console.WriteLine("FOUND THE ADDRESS"); Console.WriteLine("----------------------------------------"); } 

输出：

 browser: System.__ComObject DNSSDFlags 2 ifIndex 32 serviceName: AXIS M1011-W - 00408CBEEAE5 regtype: _http._tcp. domain: local.

我首先检查的是与_http._tcp记录关联的TXT记录。 从屏幕截图中选择_axis-video._tcp，它会显示与之关联的macaddress。 许多_http._tcp条目记录了获取它所需的URL，或者需要的端口/ ipaddress。 我先挖掘它。

否则，您可能必须将macaddress解析为ipaddress。 我用谷歌搜索了http://www.mostthingsweb.com/2011/11/reading-arp-entries-with-c/
