什么是主机名，而在卓悦1.0调用的getaddrinfo（....）而在、主机名、卓悦、getaddrinfo
我用扫描通过我的本地家庭网络卓悦1.0 （NET）的服务与 regtype =_http._tcp：
DNSSDService服务=新DNSSDService（）;
DNSSDEventManager eventmanager进行=新DNSSDEventManager（）;
eventManager.ServiceFound + =新_IDNSSDEvents_ServiceFoundEventHandler（eventManager_ServiceFound）;
DNSSDService浏览= service.Browse（0，0，_http._tcp，空，eventmanager进行）;
当我发现该服务的方法：静态无效eventManager_ServiceFound（DNSSDService浏览器，DNSSDFlags标志，UINT的ifIndex，串服务名，字符串regtype，串域）调用
然后，在该方法我想使用方法： DNSSDService的getaddrinfo（DNSSDFlags glags，UINT的ifIndex，DNSSDAddressFamily addressFamily， 字符串主机名 ，DNSSDEventManager eventmanager进行）来了解服务的IP地址和端口。
问题的是，我不知道知道什么是 字符串主机名 应，因此我不明白任何结果：**请看：???什么这里？在code **

解决方案
东西，我会首先检查与_http._tcp记录相关联的TXT记录。从截图中你有_axis-video._tcp选中，就说明你与它相关的MACADDRESS。许多_http._tcp条目记录需要得到它的URL，或所需要的端口/ ip地址。我钻进去，第一。
否则，你可能需要解决MACADDRESS到一个ip地址。我用Google搜索，并配备了 http://www.mostthingsweb.com / 2011/11 /读ARP-项，与-C /
I scanned through my local home network using Bonjour 1.0(.NET) for services with 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);
When I find the service the method: static void eventManager_ServiceFound(DNSSDService browser, DNSSDFlags flags, uint ifIndex, string serviceName, string regtype, string domain) is invoked.
Then in that method I want to use method: DNSSDService GetAddrInfo(DNSSDFlags glags, uint ifIndex, DNSSDAddressFamily addressFamily,string hostname, DNSSDEventManager eventManager) to get to know service's ip address and port.
The problem is that I do not know know what string hostname should be and thus I do not get any results: ** Please look at the: ???WHAT HERE?? in the code**
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("----------------------------------------");
}
Output:
browser: System.__ComObject
DNSSDFlags 2
ifIndex 32
serviceName: AXIS M1011-W - 00408CBEEAE5
regtype: _http._tcp.
domain: local.

解决方案
Something that I'd check first is the TXT record associated with the _http._tcp record. From the screenshot you have the _axis-video._tcp selected and it shows you the macaddress associated with it. Many _http._tcp entries record the url needed to get to it, or the port/ipaddress needed. I'd dig into that first.
Otherwise you may have to resolve the macaddress into an ipaddress. I googled and come with http://www.mostthingsweb.com/2011/11/reading-arp-entries-with-c/
