Question

I have a 2d array of strings

string [] [] myArray;

and I want to sort it by one of the columns.

So the data might be

{ "Apple", "2", "Bob" },
{ "Banana", "1", "Fred" }

And I want to sort it by any of those columns – I’ll have an index.

Ideally, I’d like to do something like myArray.Sort(1);

I understand I may have to use a custom comparer. I see this as an interesting learning opportunity. Can anyone offer some advice?

Answer 1

var myOrderedRows = myArray.OrderBy(row => row[columnIndex]);
