In the previous lesson, I talked about the fact that LINQ actually delays the execution of its constituent queries up until the very last moment, when we actually need the data. What was not as obvious at the time was the order in which the LINQ queries are executed.… Read more

Of course, since we know that iterators are used to… duh! iterate on collections of data, and since we know that when iterating on a collection, we can use the break keyword to immediately terminate the iteration, it is only obvious that whenever we use an yield return statement to return values in an iterator, like I’ve shown in the previous lesson, we can also use yield break to terminate the iteration of the said iterator.… Read more

Monday, February 22nd, 2021In the previous lesson, I have talked about IEnumerable and IEnumerator, and how they help us when we need to iterate over collections of data. Let’s take an example that deals with those concepts:
We have a function, GenerateRandomNumbers(), inside which we declare a List of ints, generate a number of random ints, equal to the _count parameter, add those random ints to the list, then return the list.… Read more
