list the gpo using namespace using Microsoft.GroupPolicy;

hi,
i would like to check the gpo in the machine to be sure that all the gpo are configured
to do this i need some help to know how can i list the gpo in the system.

i don t know if it s better to acces to the registry and check the value gpodisabled for each gpo existing or it s better to use the namespace microsoft.GroupPolicy(but i dont find the methods to use)
thanks
