C# - How to extract a list of one particular array member from a list of arrays

Question

Given a list of arrays, I'd like to extract the second member of each array in the list to a list of strings.

For example, say the list of arrays contains: {"1", "A", "X"} {"2", "B", "Y"} {"3", "C", "Z"}

then what I'd like the output to be is a list of strings containing: "A", "B" & "C"

so that I could say:

List<string> myListOfStrings = new List<string>();

myListofStrings.AddRange(???)

Answer 1

If you know for sure that all arrays have element at index 1, you could do it with LINQ in a single line:

var myListOfStrings = listOfArrays.Select(a => a[1]).ToList();
