C# 在Bonjour 1.0中调用GetAddrInfo（..）时的主机名是什么

我使用

Bonjour 1.0

（.NET）扫描了我的本地家庭网络，以获得

regtype=“\u http.\u tcp”

：

当我找到服务时，调用方法：

static void eventManager\u ServiceFound（DNSSDService浏览器、DNSSDFlags标志、uint ifIndex、字符串serviceName、字符串regtype、字符串domain）

然后在该方法中，我想使用方法：

DNSSDService GetAddrInfo（DNSSDFlags-glags，uint-ifIndex，DNSSDAddressFamily-addressFamily，

字符串主机名

，DNSSDEventManager-eventManager）

来了解服务的ip地址和端口

问题是我不知道字符串主机名应该是什么，因此我没有得到任何结果：*请查看：？？？这里是什么？？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.

我首先要检查的是与_http.\u tcp记录关联的TXT记录。从屏幕截图中，您选择了_axis-video._tcp，并显示与之相关的macaddress。许多\u http.\u tcp条目记录访问它所需的url或所需的端口/IP地址。我会先研究一下

---

否则，您可能必须将macaddress解析为ipaddress。我在谷歌上搜索并附带了

现在我可以将mac地址解析为ip地址，但您发布的内容似乎更简单（我使用的是：）。我会检查的。但是我不知道如何找到这个TXT记录。
