Remarks

SNMP PDU class that is the bases for all SNMP requests and replies. It is capable of processing SNMPv1 GET, GET-NEXT, REPLY and SNMPv2 GET, GET-NEXT, GET-BULK, REPLY, V2TRAP, INFORM and REPORT PDUs.
CopyC#
Pdu pdu = new Pdu();
pdu.Type = PduType.Get;
pdu.VbList.AddVb("1.3.6.1.2.1.1.1.0");
pdu.VbList.AddVb("1.3.6.1.2.1.1.2.0");
By default, Pdu class initializes the RequestId (unique identifier of each SNMP request made by the manager) with 0 and during the encoding process, selects a random value for the RequestId. If you wish to set a specific RequestId, you can do it this way:
CopyC#
Pdu pdu = new Pdu();
pdu.Type = PduType.GetNext;
pdu.RequestId = 11; // Set a custom request id
pdu.VbList.AddVb("1.3.6.1.2.1.1");
Pdu types with special options are notification PDUs, V2TRAP and INFORM, and Get-Bulk requests. Get-Bulk request is available in version 2c and 3 of the SNMP. Two special options can be set for these requests, NonRepeaters and MaxRepetitions. NonRepeaters is a value telling the agent how many OIDs in the VbList are to be treated as a single GetNext request. MaxRepeaters tells the agent how many variable bindings to return in a single Pdu for each requested Oid.
