Are C# events synchronous?
...y.
The event handlers are executed sequentially, one after another, in the order they are subscribed to the event.
I too was curious about the internal mechanism of event and its related operations. So I wrote a simple program and used ildasm to poke around its implementation.
The short answer i...

How do you get the index of the current iteration of a foreach loop?
...index is beside the point. Additionally, that the linked list does have an order only strengthens Jim's position. All you need to do is number each element in order. Specifically, you can achieve this by incrementing a count while you iterate, or you could generate a list of integers with the same l...
