You have in fact discovered that events are not "first class" in C#; you cannot pass around an event as data. You can pass around a delegate to a method associated with a receiver as a first-class object by making a delegate. You can pass around a reference to any variable as a (mostly) first-class object. (I say "mostly" because references to variables cannot be stored in fields, stored in arrays, and so on; they are highly restricted compared to other kinds of data.) You can pass around a type by obtaining its Type object and passing that around.
But there is no way to directly pass around as data an event, property, indexer, constructor or destructor associated with a particular instance. The best you can do is to make a delegate (or pair of delegates) out of a lambda, as you suggest. Or, obtain the reflection object associated with the event and pass that around, along with the instance.
