Enlist my course *Beginning Object-Oriented Programming* with C# ► Download source code from Patreon ► The Iterator design pattern has always had a special place in .NET. It was the level of abstraction imposed by IEnumerable transcended concrete collections, giving rise to the magic of 'yield return' in the early days of C#. If you are thinking this is merely about traversing a set of data points, think again. .NET took the Iterator concept and introduced deferred execution, lazy evaluation of sequences, and, eventually, LINQ: the heart and soul of iterators in .NET. It diminishes the manual iterations over sequences and collections and makes coding efficient and fluid. However, with power comes responsibility. Using the IEnumerable interface in .NET has its intricacies. Iterating through the same IEnumerable more than once can be dangerous. There are instances when the data from a first iteration might vanish, especially when coming from a source like a network socket. Other implementations might cause a performance penalty, such as reiterating the result of a database query, essentially causing the query to run twice on the underlying database. Such intricacies emphasize the need for understanding the Iterator Pattern to leverage its potential fully. In essence, .NET has magnificently integrated and enhanced the Iterator design pattern. By striking a balance between high-level constructs like LINQ and low-level, detailed access via the IEnumerator, it offers developers a broad spectrum of tools. Thank you so much for watching!
