Avoid duplicate event subscriptions in C#

Question

How would you suggest the best way of avoiding duplicate event subscriptions? if this line of code executes in two places, the event will get ran twice. I\'m trying to avoid

Answer 1

I use your approach except one detail. I think, that events should be subscribed when you create new instance of subscriber or theObject, this makes code more straight. Thus, all you need is just carefully watch after correct objects disposing (dispose patten is convenient solution for this).

You mentioned that you use 3rd party event, that means that you can't provide your own realisation for add/remove methods, as you have been advised. But in your own classes with your own events you should define your own realisation of add/remove methods for event in order to solve your problem.
