将数字字符串排序

            string str = "843217965";
            char[] chars = str.ToCharArray();
            List<int> lists = new List<int>();
            foreach (char i in chars)
            {
                lists.Add(int.Parse(i.ToString()));
            }
            //lists.Sort();//sort默认是从小到大的。显示123456789
            int[] ints = lists.ToArray();
            
            
            //冒泡排序，这个是从小到大显示
            for (int i = 0; i < ints.Length; i++)
            {
                for (int j = i; j < ints.Length; j++)
                {
                    if (ints[i] > ints[j])
                    {
                        int temp = ints[i];
                        ints[i] = ints[j];
                        ints[j] = temp;
                    }
                }
            }

            for (int i = 0; i < ints.Length;i++ )
            {
                Console.Write(ints[i].ToString());
            }
