String s=a,b,c,d,e,f,g;怎么排序。倒着排序

Answer 1

string s = "a,b,c,d,e,f,g";

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

    string dec = "";
    for (int i = 0; i < str.Length; i++)
    {
        if (i == str.Length - 1)
        {
            dec += str[str.Length - 1 - i];
        }
        else
        {
            dec += str[str.Length - 1 - i] + ",";
        }

    }
