Answer 1

This should do everything you're asking:

class Program
{
    static void Main(string[] args)
    {
        string sentence = string.Empty;
        sentence = Console.ReadLine();

        var sent = sentence
            .Split(' ')
            .Distinct()
            .OrderBy(x => x);

        foreach (string s in sent)
        {
            Console.WriteLine(s.ToLower());
        }

        Console.ReadLine();
    }
}

Hope it helps!
