Display list of strings with only one string which is separated by (,) and (\n)-CodePudding

I need to convert list of strings which contains one long string where values are separated with , and \n. Example:

string[] namesArray = {"Name1,Surname1", "Name2,Surname2", "Name3,Surname3"};`

string nameSting = "";

foreach(string nameFromArray in namesArray) {
  nameSting  = nameFromArray   "\n";
}

List<string> namesList = new List<string>();
namesList.Add(nameSting);

My question is how can I process namesList so Console.WriteLine outputs the following format:

1. Name1 Surname1
2. Name2 Surname2
3. Name3 Surname3

Please note that nothing above can be changed. I know it's a weird code but it's a very simplified way to show how API returns data which needs to be converted in the format described above.

The following

string[] namesArray = {"Name1,Surname1", "Name2,Surname2", "Name3,Surname3"};
int index = 1; 
namesArray.ToList().ForEach(n => {Console.WriteLine(index   ". "   n.Replace(',', ' ')); index  ;});

will output:

1. Name1 Surname1
2. Name2 Surname2
3. Name3 Surname3

Don't forget to include the following using statements:

using System.Linq;
using System.Collections.Generic;

Split by new line and then split by comma

var names = namesList
    .SelectMany(t => t.Split(new string[] { Environment.NewLine }, StringSplitOptions.None))
    .Select(name => name.Split(','))
    .Select((name, index) => (Index: index, FirstName: name[0], Surname: name[1]));

foreach(var name in names)
{
    Console.WriteLine($"{name.Index}. {name.FirstName} {name.Surname}");
}
