How to display a list in descending order

[mg72266]

Is there a way to display a list in descending order?

Given an array,

var array = new List<string> { "555100", "555101", "555102" };

I have a string that I format it like so,

var string = Smart.Format("array - {0:{:substr(3)}| }", array)

Am I able to format the string so I can have the array appear in descending order without reversing the array object?
