Sort a List by the second value (int)

Question

I have a list

List<string[]> listname = ...

The list looks like this:

[string][string][string]

I want to sort the list by second string.

The second string is a number presented as a string, i want to keep it that way, i need it like this.

I want the numbers to be in Increasing order.

Example for data:

["RDP"]["3389"]["TCP"] 
["HTTP"]["80"]["TCP"]
["HTTPS"]["443"]["TCP"]

I want to sort by the post number.

In this example "RDP" will become the last one.

How can I do so?

Please give us an example of the contents of the list. As you have phrased it currently, it's hard to understand. — Theodoros Chatzigiannakis, Jun 24 '15 at 14:03
See duplicate. Just as you'd do with `.OrderBy(f => f.Foo)` you can use `.OrderBy(f => f[1])`. — CodeCaster, Jun 24 '15 at 14:04

Yes, it does. If you think it doesn't, create an example (which doesn't need external data) that reproduces the problem, and explain what you'd expect to see and what you actually see. — CodeCaster, Jun 24 '15 at 14:11

var sortedList = listname.OrderBy(l => int.Parse(l[1]));

This assumes that the second entry in each array is parsable as int. If you're not sure about that, you'd need to add some checks and maybe use int.TryParse.

You can refer to appropriate index of an array in OrderBy:

var l = new List<string[]>() { 
                                new string[] { "a", "b", "c" }, 
                                new string[] { "b", "a", "c" }, 
                                new string[] { "c", "c", "c" }, 
                                };
var s = l.OrderBy(c => c[1]).ToList();
