Access to Modified Closure

by

In this case, it’s okay, since you are actually executing the delegate within the loop.

If you were saving the delegate and using it later, however, you’d find that all of the delegates would throw exceptions when trying to access files[i] – they’re capturing the variable i rather than its value at the time of the delegates creation.

In short, it’s something to be aware of as a potential trap, but in this case it doesn’t hurt you.

See the bottom of this page for a more complex example where the results are counterintuitive.
