I've encountered this operator in C# when dealing with custom events: MyEvent?.Invoke(this, new EventArgs());. What is the purpose of the ?. portion of this statement?

Yup, definitely a dup. For some reason that question didn't come up when I searched... the syntax seems to bugger up the search engine for some reason. – JTW Apr 20 '17 at 01:25

1Yeah, it's hard to find what operators mean in C#. The best place to look is the [MSDN article](https://msdn.microsoft.com/en-us/library/6a71f45d.aspx) then at least you get the right name to search for. – Steve Apr 20 '17 at 01:28

It's making sure it's not null. They have these in swift and their called optionals. If the variable is null then it returns null

It most definitely is not an option type, it's a null coalescing operator. – Rob Apr 20 '17 at 01:40
