示例1: DiscoverAsync
public static async Task<bool> DiscoverAsync(object state = null)

sock.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1);

byte[] outBuf = Encoding.ASCII.GetBytes(BroadcastPacket);
byte[] inBuf = new byte[4096];
int tries = MaxTries;
while (--tries > 0)
{
try
{
TaskFactory factory = new TaskFactory();
sock.ReceiveTimeout = DiscoverTimeout;
await factory.FromAsync(sock.BeginSendTo(outBuf, 0, outBuf.Length, 0, endpoint, null, null), end =>

}).ConfigureAwait(false);
var ar = sock.BeginReceive(inBuf, 0, inBuf.Length, 0, null, null);
if (ar == null) throw new Exception("ar is null");
int length = await factory.FromAsync(ar, end => sock.EndReceive(end)).ConfigureAwait(false);
string data = Encoding.ASCII.GetString(inBuf, 0, length).ToLowerInvariant();
