Answer 1

    public static List SplitByMaxLength(this string str)
    {
        List splitString = new List();

        for (int index = 0; index < str.Length; index += MaxLength)
        {
            splitString.Add(str.Substring(index, Math.Min(MaxLength, str.Length - index)));
        }

        return splitString;
    }
