什么是主机名，而在卓悦调用的getaddrinfo（....）1.0

Question

我通过使用Bonjour 1.0（.NET）为服务我的本地家庭网络扫描，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); 

当我发现服务的方法：调用static void eventManager_ServiceFound(DNSSDService browser, DNSSDFlags flags, uint ifIndex, string serviceName, string regtype, string domain)。

然后在那个方法我想使用方法：DNSSDService GetAddrInfo(DNSSDFlags glags, uint ifIndex, DNSSDAddressFamily addressFamily,string hostname, DNSSDEventManager eventManager)结识服务的IP地址和端口。

问题是，我不知道知道string hostname应该是什么，因此我没有得到任何结果：**请看：WHAT ??? ?? HERE在代码**

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.

      Console.WriteLine("----------------------------------------");

Answer 1

的东西，我会先检查与_http._tcp相关的TXT记录记录。从屏幕截图中选择_axis-video._tcp，并向您显示与之关联的macaddress。许多_http._tcp条目记录到达它所需的url，或所需的端口/ ip地址。我会先深入研究。

否则，您可能必须将macaddress解析为ip地址。我GOOGLE搜索并与http://www.mostthingsweb.com/2011/11/reading-arp-entries-with-c/
