C#/linq: order list of strings by its title ("Article 3", "Article 15")

Question

I have a list of Item objects (C#):

List itemList.

the Item object has a property Title, with values varying between ("Article 3:", "Article 14:", "Article 233: dfsdf", etc).

when I sort in the regular LINQ way, like this:

itemList.OrderBy(p => p.Title).ToList();

Article 14 is sorted before Article 3, because it starts with 1. How do I sort this collection in the right way?

Refactor your class and add a `ArticleNumber int` property, then sort by that. Don't store multiple informations in a single string property. — Tim Schmelter, Dec 19 '16 at 13:47
@TimSchmelter agreed, this seems like the cleanest solution, will give that a try. thanks — stefjnl, Dec 19 '16 at 14:01

You can define a property with a getter only on the Object, that will load from the Title just the numbers (maybe by splitting the title by " ", or by replacing the Article text, then trimming the result ), and use the new property in the OrderBy.
