用vs2013 web实验题 以空格间隔的共10个以内的整数 输出该组整数的降序排列

如何改写能够完成包含0和负数的排序
string sInput = txtInput.Text.Trim() + " ";

        int j = 0;
        int[] aInput = new int[10];
        string temp = "0";
        for (int i = 0; i <= sInput.Length - 1; i++)
        {
            if (sInput.Substring(i, 1) != " ")
            {
                temp += sInput.Substring(i, 1);
            }
            else
            {
                aInput[j] = int.Parse(temp);
                j++;
                temp = "0";
            }
        }
        Array.Sort(aInput);
        Array.Reverse(aInput);
        foreach (int i in aInput)
        {
            if (i != 0)
            {
                Response.Write(i + "&nbsp;&nbsp;");
            }
        }

    }

 string sInput = txtInput.Text.Trim();
Response.Write(string.Join(" ", sInput.Split(' ').Select(x => int.Parse(x)).OrderBy(x => x).Select(x => x.ToString()).ToArray()));

 string str = "123 9 0 -7 -5 18";
            var result = str.Split(' ').OrderByDescending(t => int.Parse(t));
            foreach (var r in result)
            {
                Console.WriteLine(r);
            }
