in the Index.cshtml

    <table class="table">

I have created a model of a book based on a list of a file.txt in order to display a table with all the books available, their author, publisher and price, now, for each book, I should be able to open a descriptive sheet also containing ISBN , pages and quantities. From paragraph in the html below @Html.DisplayFor(modelItem => line.Titolo) I inserted a link to the About.cshtml, but I don't know what code to write inside and what to write in the controller too?

this is my controller at the moment:

public ActionResult Index()
        {
            var fileInput = Reader.Read("C:/Users/test/source/repos/Books/Books/App_Data/Libri.txt");

            var libriList = new List<Libro>();
            if (fileInput != null)
            {
                for (var i = 1; i < fileInput.Count; i++)
                {
                    var libri = new Libro();
                    libri = libri.BuildLibro(fileInput[i]);

                    if (libri != null)
                    {
                        libriList.Add(libri);
                    }
                }
            }
        Session["currentLibriList"] = libriList;
        return View(libriList);
    }

       public ActionResult About(string titoloId)
    {
        var myFilteredList = new List<Libro>();
        if (Session["currentLibriList"] != null)
        {
            var lookupList = (List<Libro>)(Session["currentLibriList"]);
            myFilteredList = (List<Libro>)lookupList.Where(x => x.Titolo == titoloId);
        }
        return View(myFilteredList);
    }

and this is About.cshtml

<html>
<body>

    <table class="table">
        @foreach (var line in Model)
        {
        <tr>
            <td>
                @Html.DisplayFor(modelItem => line.Titolo)
            </td>
            <td>
                @Html.DisplayFor(modelItem => line.Autore)
            </td>
            <td>
                @Html.DisplayFor(modelItem => line.Editore)
            </td>
            <td>
                @Html.DisplayFor(modelItem => line.Prezzo)<p>€</p>
            </td>
            <td>
                @Html.DisplayFor(modelItem => line.Pagine)
            </td>
            <td>
                @Html.DisplayFor(modelItem => line.Quantità)
            </td>
            <td>
                @Html.DisplayFor(modelItem => line.ISBN)
            </td>

        </tr>
        }

    </table>
</body>
</html>
