Question

This is probably a really easy question, I want to access the last element of:

List<string>[] list = new List<string>[3];

So each list inside has 3 elements but how should I access the last of those lists?

Answer 1

You can use Enumerable.Last():

string lastElement = list.Last().Last();

The first call will return the last List<string>, and the second will return the last string within that list.

Alternatively, since you know the length of the array, you can access the list directly, and do:

string lastElement = list[2].Last();

If you know, in advance, that you’re always going to have 3 lists with 3 elements, you might want to consider using a multidimensional array instead:

string[,] matrix = new string[3,3];

// fill it in..

string last = matrix[2,2];
