在txtA文本框中输入任意个数字以逗号分隔,点击button,txtB文本框中显示将txtA文本框中的数字按从小到大的顺序排序后的结果,依然用逗号分割,请教高手,谢谢!

string s = "1,3,9,18,4,2,0,55,33,22";

            string[] number = s.Split(',');

            for (int i = number.Length - 1; i > 0; i--)

            {

                for (int j = 0; j < i; j++)

                {

                    int a = int.Parse(number[j]);

                    int b = int.Parse(number[j + 1]);

                    if (a > b)

                    {

                        string swap = number[j];

                        number[j] = number[j+1];

                        number[j+1] = swap;

                    }

                }

            }

            

            s = string.Join(",", number);

大概这个意思。测试下吧。
string s = "1,2,3,6,4,8,10";
string[] values = s.Split(new char[] { ',' });
for (int i = values.Length-1; i > 0; i--)
{
for (int j = 0; j < i; j++)
{
if (Convert.ToInt32(values[j]) > Convert.ToInt32(values[j + 1]))
{
string temp = values[j];
values[j] = values[j + 1];
values[j + 1] = temp;
}
}
}
s="";
for (int i = 0; i < values.Length; i++)
s += values[i] + ",";
