            List<string> list = new List<string>(); // Результат
            for (int i = 1; i < lines.Length; i++)
            {
                if (lines[i] == "")
                    continue;
                // string[] lineParts = lines[i].Split(' ');
                list.Add(lines[i]);
            }
