            Console.WriteLine(s1);
            Console.ReadKey();

static string Join(string[] strs, string seperater)//加上分隔符“－”
        {
            string result = "";
            for (int i = 0; i < strs.Length - 1; i++)
            {
                result = result + strs[i] + seperater;
            }
            if (strs.Length > 0)
            {
                result = result + strs[strs.Length - 1];
            }
            return result;
        }

运行结果：834858-12-34513-99
