Array.ConvertAll - the day I found about it was the day I learned I could not use it anymore
I found these cool websites where you can solve software challenges. Completely randomly I find out about this method that I found pretty cool, called Array.ConvertAll. Imagine you want to transform a string containing a space separated list of integers into an actual list of integers. You would use Array.ConvertAll(line.Split(' '),int.Parse). That is it. I liked the simplicity of it and also the fact that it works out of the box without having to import any namespace. The same thing can be achieved with LINQ thus: line.Split(' ').Select(int.Parse).ToArray(), but you need to import the System.Linq namespace.
Unfortunately, the same day I found about this method that I had never used before yet is there since .NET 2.0, I noticed that it doesn't exist in .NET Core. Like a butterfly, it only lived one day in my development repertoire.

Yeah, you're right! I'll edit the post. I actually thought of it that way when I wrote it, then somehow it came out as a lambda. Booo, me!
SideriteNote that the LINQ version can be shortened to `line.Split(' ').Select(int.Parse).ToArray()`, which looks pretty sweet IMHO. I didn't know about `Array.ConvertAll()`. Thanks for sharing!
