Given the text, it must be divided into sentences, and sentences into words. So, you need to create a List sentences and place sentences there, and then create a List> words and put the words there, right? Or sentences should be a sheet of sheets, and the words just a sheet. So, how to add elements to the sheet of sheets.

Please help me, I don’t understand how to work with lists at all.

And they say that recursion is divine!

Let's start with the biggest nesting, with the words that make up the sentence.

var sentence = new List<string>(); sentence.Add("Hello"); sentence.Add("world");

Words are combined into sentences that make up the text:

 var text = new List<List<string>>(); var sentence = new List<string>(); sentence.Add("Hello"); sentence.Add("world"); text.Add(sentence);

The last code can be rewritten as follows:

 var text = new List<List<string>>(); text.Add(new List<string>()); text[text.Count - 1].Add("Hello"); text[text.Count - 1].Add("world");

Here we first add an empty sentence to the text, and then add words to the last ( text[text.Count - 1] ) text sentence.

If we had another level of nesting, for example, a card file, which consists of texts, it would look like this:

 var directory = new List<List<List<string>>>(); var text = new List<List<string>>(); var sentence = new List<string>(); sentence.Add("Hello"); sentence.Add("world"); text.Add(sentence); directory.Add(text);

    As an option:

     var sentenseList = inputText .Split(new[] { "." }, StringSplitOptions.RemoveEmptyEntries) .Select(x => x.Split(new[] { "-", " ", "," }, StringSplitOptions.RemoveEmptyEntries).ToList()) .ToList();

    Where inputText is a string variable containing the input text to parse.
