推荐答案

我得到了这个

and i got this

 static void Main(string[] args)
        {
            string[] items = new string[] { "TO - 1","TO - 2","TO - 3","TO - 4","TO - 15","To - 18","TI - 50","TI - 58","TI - 59","TO - 60","TO - 63" };

 string asc = string.Join(",", items.OrderBy(k => k)); //TI - 50,TI - 58,TI - 59,TO - 1,TO - 15,To - 18,TO - 2,TO - 3,TO - 4,TO - 60,TO - 63
string desc = string.Join(",", items.OrderByDescending(k => k)); //TO - 63,TO - 60,TO - 4,TO - 3,TO - 2,To - 18,TO - 15,TO - 1,TI - 59,TI - 58,TI - 50
        
        }
