how to get objectID from ManagedObjectReference

hi All,

i want to use object id of vmware object,(host , vm, clusters etc). i saw the sample codes and i am aware of getting it from web_platform.

but in my condition i am working in generic workspace(not in that object's context) so i cant use web_platform.

can some one help me how to generate objectId using ManagedObject Reference of that object.

i want to use it for sendNavigationRequest

Thanks in advance
