C# sort Arraylist strings alphabetical and on length

Question

I\'m trying to sort an ArrayList of String.

Given:

{A,C,AA,B,CC,BB}

Arraylist.Sort gives:

Answer 1

It's easier to do this with Linq as so:

string [] list = { "A","C","AA","B","CC","BB"};

var sorted = list.OrderBy(x=>x.Length).ThenBy(x=>x);

Note that the OrderBy method returns a new list. If you want to modify the original, then you need to re-assign it as so:

list = list.OrderBy(x=>x.Length).ThenBy(x=>x).ToArray();
