When you first asked this question I read it but could not provide much insight.
What #SNMP offers are the two set of functions below,
MessageFactory.ParseMessage
, a few functions that parse raw bytes toISnmpMessage
.ISnmpMessage.ToBytes
, a method that generates raw bytes.
If you can write adapters to bridge #SNMP and Pcap.NET, you should be able to achieve what you want.
Next time, make sure you avoid C# tag, as yes you might be down voted due to that.
