List<T>.GetEnumerator() returns a mutable value type (List<T>.Enumerator). You’re storing that value in the anonymous type. Now, let’s have a look at what this does: while (x.TempList.MoveNext()) { // Ignore this } That’s equivalent to: while (true) { var tmp = x.TempList; var result = tmp.MoveNext(); if (!result) { break; } // Original loop body } … Read more
While the break solution works, I think a more functional approach really suits this problem. You want to take the first 10 elements and print them so try items.take(10).each { |i| puts i.to_s }
Here are 3 ways to do it specifically with a FormCollection object. public ActionResult SomeActionMethod(FormCollection formCollection) { foreach (var key in formCollection.AllKeys) { var value = formCollection[key]; } foreach (var key in formCollection.Keys) { var value = formCollection[key.ToString()]; } // Using the ValueProvider var valueProvider = formCollection.ToValueProvider(); foreach (var key in valueProvider.Keys) { var value … Read more
Sergio’s answer is very good, but it’s worth pointing out that there is a keyword that works the way you wanted return to work: next. array.map do |x| if x > 10 next x + 1 else next x – 1 end end This isn’t a very good use of next because, as Sergio pointed … Read more
In the usual encoding an enumerator is essentially a StepT[E, F, ?] ~> F[StepT[E, F, ?]]. If you try to write a generic method converting this type into a Step[E, G, ?] ~> G[Step[E, G, ?]] given an F ~> G, you’ll quickly run into an issue: you need to “lower” a Step[E, G, A] … Read more
