                    tl.Add(x);
                    groups.Add(tl);
                }
                else
                {
                    groups[groups.Count - 1].Add(x);
                }
                t = x;
            }
            return groups;
        }
        //string 数组转换long数组
        public static long[] convertionToLong(string[] strs)
        {
            // 将String数组转换为Long类型数组
            long[] longs = new long[strs.Length]; //声明long类型的数组
            for (int i = 0; i < strs.Length; i++)
            {
                String str = strs[i];       //将strs字符串数组中的第i个值赋值给str
                long thelong = Convert.ToInt64(str);//将str转换为long类型，并赋值给thelong
                longs[i] = thelong;//将thelong赋值给 longs数组中对应的地方
            }
            return longs;  //返回long数组
        }

　　　　　　　　　　 long[] testcount = convertionToLong(ticketcount);
