Using C# to compare to Featureclasses

I'm trying to compare 2 linear featureclasses and see where their PROPERTY_ID is not the same.  What is the best way to do this?  Right now I have one Do While loop with a Prop_ID value of one FC and another Do While inside that loop that checks against each record in the other FC against that Prop_ID value.  It is slow and not working correctly.

FC1 has about 675 records and FC2 has about 505.  So I need to determine what Prop_ID(s) are missing from FC2 and then I have some code that will copy the record from FC1 based on Prop_ID into FC2.  Just need to determine missing Prop_ID(s) first..
