Sort specific values inside a list through LINQ

Question

Hi I currently have a list of strings with values:

*Item1, *Item2, Test2, Test4, *Item3, Test1, *Item4, *Item5

How do I re-arrange them and have all the values with asterisk to be in the first part of the list such as this while maintaining the order of the non-asterisk items:

*Item1, *Item2, *Item3, *Item4, *Item5, Test2, Test4, Test1

which criteria are you using for sort? doesn't `list.Sort();` solve it for you? — Hoshani, Oct 14 '20 at 07:11
`string[] items = {"*Item1", "*Item2", "Test2", "Test4", "*Item3", "Test1", "*Item4", "*Item5"}; var result = items.OrderBy(x=>x);` — Maciej Los, Oct 14 '20 at 07:12

It's unclear if you want to order the asterisk part on simply put them first. In your example all asterix are already ordered making this special case unclear. — Drag and Drop, Oct 14 '20 at 07:29

Simple OrderByDescending will do the thing

var str = "*Item1, *Item2, Test2, Test4, *Item3, Test1, *Item4, *Item5";
var arr = str.Split(new char[] { ' ', ',' }, StringSplitOptions.RemoveEmptyEntries);

var ordered = arr.OrderByDescending(x => x.StartsWith("*")).ToArray();

This simply put the asterisk first. "_while maintaining the order of the non-asterisk items_"., perhaps imply it was only for the non-asterisk. – Drag and Drop Oct 14 '20 at 07:30
