There are plenty of programming languages out there and they all allow endless possibility in how to write a piece of code.
Very often things can be done in two ways: the blunt way and the elegant way.
Consider for instance this piece of code:
[…] For Each SingleFeed As XElement In XMLDoc.Descendants(XName.Get(CurrentFeed.RootElement)) Dim SyndFeed As SyndicationFeed = SyndicationFeed.Load(System.Xml.XmlReader.Create(SingleFeed.Descendants(XName.Get("feed")).Value.ToString)) Dim TempItems As New List(Of SyndicationItem) If SyndFeed.Items.Count >= CurrentFeed.TotalElements Then TempItems.AddRange(SyndFeed.Items.ToList.GetRange(0, CurrentFeed.TotalElements)) Else TempItems.AddRange(SyndFeed.Items.ToList) End If […] FeedItems.AddRange(TempItems) Next […]
It has to do with the creation of an object to store items from an ATOM feed.
The important point I want to show is the one about the If … else … End If cycle. What you are looking here is the first implementation of the code: it’s the easy way and, as i discovered later, the longest and stupidest way to write it.
Yes, it was stupid: the compact, most logical and briefly the elegant way to wrote it turned out to be:
TempItems.AddRange(SyndFeed.Items.ToList.GetRange(0, Math.Min(CurrentFeed.TotalElements, SyndFeed.Items.Count)))
Probably any coding language nowadays includes some kind of Minimum function to return the smallest of two numbers.
Very often is just a matters of knowing what you are doing.
