Snmp Manager Using C#

hi friends,
I am An IT Student at Melbourne. I got a Project in which i have to use SNMP MAnager Using c# for Windows Platform (Specially for Windows XP). I got some IDEA About SNMP after reading MSDN, RFC etc. But now i am having problem to integrate it with C#. As i come to know that there is no direct support for SNMP in .NET Framework. There are some DLL files (i.e. Winsnmp.dll etc.). But i dont know how to use them with C#. So, Can any one pls help me with this.
Thanks in Advance.
