Hi,
On MS.NET it appears that when the UdpClient class is used the socket it
creates has broadcasting enabled. On Mono it is disabled. I have attached a
(totally trivial) patch to UdpClient.cs that resolves this.
Here is a test case that demonstrates the problem (works on MS, fails on
Mono):
[Test]
public void UdpClientBroadcastTest() {
bool exThrown = false;
UdpClient client = new UdpClient(new
IPEndPoint(IPAddress.Loopback,1234));
byte[] bytes = new byte[] {10,11,12,13};
try {
client.Send(bytes,bytes.Length,new
IPEndPoint(IPAddress.Broadcast,1235));
} catch (SocketException) {
exThrown = true;
}
Assert.IsFalse(exThrown,&quot;UdpClient Broadcast #1&quot;);
}
Chris
