how to set MulticastInterface

[PHLICS_Admin]

Hi All,

Following code is used to set multicast interface :

IPAddress ipLan = IPAddress.Parse("...");
int iIP = (int)(ipLan.Address) ;
this._clsMCastSender.SetSocketOption(SocketOptionLevel.IP,
SocketOptionName.MulticastInterface , iIP) ;

When the IP address is "192.168.0.231" , Overflow error occur.

Would you please give me some advise about how to solve it .

Thanks,

Phlics

Hi,
uhm... I'm not exactly sure what you are trying to do, but did you take
a look at the sample code in MSDN?

There is some code at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/
frlrfSystemNetSocketsMulticastOptionClassTopic.asp

Also, one problem could be related to the IP address you are using:
take a look at RFC 1112 and RFC 1301, http://www.faqs.org/rfcs/ for example)

Hope it helps.
