New Post: varbind list construction

If we start from the sample code on that page, you can see how to construct the simplest variable binding via

    # Create OID variable list
    $vList = New-GenericObject System.Collections.Generic.List Lextm.SharpSnmpLib.Variable                        # PowerShell v1 and v2
    # $vList = New-Object 'System.Collections.Generic.List[Lextm.SharpSnmpLib.Variable]'                          # PowerShell v3
    foreach ($sOID in $sOIDs) {
        $oid = New-Object Lextm.SharpSnmpLib.ObjectIdentifier ($sOID)
        $vList.Add($oid)
    }

To fulfill your needs of setting OCTET STRING value for each of the variables, the only change you need to make is to use another constructor of Lextm.SharpSnmpLib.ObjectIdentifier,

To pass the data you want, use one of OctetString's constructors to construct a new object,
