✅ getting length of a list???

In my database file, I have a function that loads all of the ghost items back into a list and returns it

public List<Ghost>? LoadGhosts()
{
    var ghostInfo = File.ReadAllText(dbFile);
    List<Ghost> ghosts = new List<Ghost>();
            
    foreach (Ghost ghost in ghosts)
    {
        Ghost g = JsonSerializer.Deserialize<Ghost>(ghostInfo);
        ghosts.Add(g);
    }

    return ghosts;
}

public List<Ghost>? LoadGhosts()
{
    var ghostInfo = File.ReadAllText(dbFile);
    List<Ghost> ghosts = new List<Ghost>();
            
    foreach (Ghost ghost in ghosts)
    {
        Ghost g = JsonSerializer.Deserialize<Ghost>(ghostInfo);
        ghosts.Add(g);
    }

    return ghosts;
}

and in my game file, I am obtaining that list and attempting to get the length of it

public static void PlayGame(string selectedDiff, string username, DateTime date)
{
    Database db = new Database();
    var ghosts = db.LoadGhosts();
    int randGhostIndex = Helpers.RandomNumber(0, ghosts.Length);
}

public static void PlayGame(string selectedDiff, string username, DateTime date)
{
    Database db = new Database();
    var ghosts = db.LoadGhosts();
    int randGhostIndex = Helpers.RandomNumber(0, ghosts.Length);
}

I'm passing the length of the list to my random number generator, however, it says that ghosts doesn't have the Length property, so how do I get the length of the ghosts list to pass to my random number generator?
