Answer by John Wigger for LINQ equivalent of foreach for IEnumerable

There is an experimental release by Microsoft of Interactive Extensions to LINQ (also on NuGet, see RxTeams's profile for more links). The Channel 9 video explains it well.

Its docs are only provided in XML format. I have run this documentation in Sandcastle to allow it to be in a more readable format. Unzip the docs archive and look for index.html.

Among many other goodies, it provides the expected ForEach implementation. It allows you to write code like this:

int[] numbers = { 1, 2, 3, 4, 5, 6, 7, 8 };

numbers.ForEach(x => Console.WriteLine(x*x));
