C#: SNMP - VMS - DMS [on hold]

My name is Renan and I'm from Brazil. I am developing a solution for ITS.
I need to access information via SNMP from a device called PMV.
I am using the following code:
http://www.java2s.com/Code/CSharp/Network/SimpleSNMP.htm
But I can not get back in the "Value" only "Datatype". Someone has
knowledge and could help me?
Below follows the return of the above code
