How to sort descending a string list contains strings with alphabets & numbers in C# .net?

Question

I have values in a string list like

AB1001_A
AB1001_B
AB1002_2
AB1002_C
AB1003_0
AB1003_
AB1003_B
AB1003_A
AB1001_0
AB1001_1
AB1001_2
AB1001_C
AB1002_B
AB1002_A

And I wanted to sort this by ascending order and the suffixes in descending order like below

AB1001_2
AB1001_1
AB1001_0
AB1001_C
AB1001_B
AB1001_A
AB1002_0
AB1002_B
AB1002_A
AB1003_0
AB1003_B
AB1003_A
AB1003_

How can I code it in C#.net?

Answer 1

Finally I got the soln by this

var mystrings = new []
            {
                "AB1001_A",
                "AB1001_B",
                "AB1002_2",
                "AB1002_C",
                "AB1003_0",
                "AB1003_",
                "AB1003_B",
                "AB1003_A",
                "AB1001_0",
                "AB1001_1",
                "AB1001_2",
                "AB1001_C",
                "AB1002_B",
                "AB1002_A",
            };


mystrings.Cast<string>().OrderBy(x => PadNumbers(x));

and then PadNumbers function as like below

        public static string PadNumbers(string input)
        {
            return Regex.Replace(input, "[0-9]+", match => match.Value.PadLeft(10, '0'));
        }
