How to access unique sublist from another class

Question

I have a list of list and I want to access for example the second sublist and add a string.

 public static List<List<string>> logsIP1 = new List<List<string>>();

 public static void logsList()
 {
        logsIP1.Add(new List<string> { });
        logsIP1.Add(new List<string> { });
        logsIP1.Add(new List<string> { });
 }

I want something like

Logs.logsIP1.Add(List<string>[0]("test");

Answer 1

Try something like:

 public static List<List<string>> logsIP1 = new List<List<string>>();
 public static void Add(int index, string value)
 {
    var nestedList = logsIP1[index];
    nestedList.Add(value);
  }

Then you can use method Add() to insert new value into nested list by index of main list
