How to make a list of string pairs ?
I want to list some string pairs. The are not key / value pairs but two strings that belong together I have lots of those pairs and want to put them in a list. I need to loop through the list. And be able to print either on of them or both. How to do that ? In my opnion it is not a dictionairy, because the key is not unique. and a list <string,string> is not allowed. https://code.sololearn.com/cA16a1a81a3A/?ref=app

sneeze I've cleaned up my code a little. It was after 3am EDT when I wrote it and I later realized I didn't save my last set of changes before crashing for the night.
Here's the simple versions to review. Let me know which you prefer and why.
var array2d = new string[,]
{ {"a", "b"},
{"c", "d"} };
var jaggedArray = new string[][]
{
new string[] {"c", "z"},
new string[] {"z", "b"} };
var listofArrays = new List<string[]>
{ new[] {"c", "d"}, new[] {"c", "z"} };
var nestedLists = new List<List<string>>
{ new List<string> {"a", "b"},
new List<string> {"a", "x"} };
var listOfTuples =
new List<(string s1, string s2)>
{ (s1: "a", s2: "b"), (s1: "z", s2: "b") };
You can review how I enumerate these in the Print extension methods found in the code. These do require very different approaches. So you may want to review those methods.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
var myList = new List<Tuple<string, string>>();
myList.Add(Tuple.Create("a", "b"));
myList.Add(Tuple.Create("c", "d"));
}
}
}
// something like above works.
Note you can also dictionary to achieve what you wanted.
ALSO, there is a typo in your code - myList
