Apple Bonjour for .Net

This code essentially listens on port 5353 for broadcasts to the group 224.0.0.251.

public void Start()
{
 try
 {
 UdpClient udpClient = new UdpClient();

udpClient.ExclusiveAddressUse = false;
 IPEndPoint localEndpoint = new IPEndPoint(IPAddress.Any, 5353);

udpClient.Client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.ReuseAddress, true);
 udpClient.ExclusiveAddressUse = false;

udpClient.Client.Bind(localEndpoint);

IPAddress multicastaddress = IPAddress.Parse("224.0.0.251");
 udpClient.JoinMulticastGroup(multicastaddress);

while (true)
 {
 Byte[] data = udpClient.Receive(ref localEndpoint);
 string dataAsString = Encoding.UTF8.GetString(data);
 Console.WriteLine(dataAsString);
 }
 }
 catch (Exception exp)
 {
 Console.WriteLine(exp.Message);
 }
 }

以Bonjour 为例，Airplay 投屏需要创建两个服务，分别是_raop._tcp.local和_airplay._tcp.local

一个简单的设备注册示例；主要分为两部分

创建一个ServiceInfo 实例
将刚刚创建的ServerInfo进行注册

并进行广播
