这个年龄计算程序相当不科学，体验还是差差哒 

 1 DateTime bdDT = new DateTime();
 2             DateTime timenow = DateTime.Now;
 3             Console.WriteLine("请输入您的年龄");
 4             int age = int.Parse(Console.ReadLine());
 5             Console.WriteLine("请输入你今年的生日，如2015-10-5");
 6             string bdST = Console.ReadLine();
 7             bdDT = Convert.ToDateTime(bdST);
 8             int intYearNow=bdDT .Year ;
 9             int intYearNext=bdDT .Year  +1;
10             int Days=0;
11             int intDay = bdDT.Day;
12             int intMonth = bdDT.Month;
13             int intDayNow = timenow.Day;
14             int intMonthNow = timenow.Month;
15             int DayNowNum=timenow .DayOfYear;
16             int DaybdNum=bdDT .DayOfYear;
17             int bdNextNum=0;
18            //判断今年是不是闰年
19             if (intYearNow%4==0&&intYearNow %100!=0)
20             {
21                 Days =366;
22                 if (intMonth >2)
23                 bdNextNum =DayNowNum-1;    //如果今年是闰年，那第二年肯定不是闰年
24                 else
25                 bdNextNum =DayNowNum;      //小于2月则每一年的第几天生日不会改变
26             }
27 
28             else

30             if (intDayNow - intDay >= 0)
31             {
32                 if (intMonthNow - intMonth >= 0)
33                     Console.WriteLine("您还有" + (intMonthNow - intMonth) + "个月零" + (intDayNow - intDay) + "天,总共" + (Days-DayNowNum + bdNextNum) + "天，就过生日啦");
34                 else
35                     Console.WriteLine("您还差" + (intDayNow - intDay) + "天不到" + (intMonth - intMonthNow) + "个月总共" + (DaybdNum - DayNowNum) + "天，就过生日啦");
36             }
37             else
38             {
39                 if (intMonthNow - intMonth >= 0)
40                     Console.WriteLine("您还差" + (intDay - intDayNow) + "天不到" + (12 - intMonthNow + intMonth) + "个月总共" + (Days - DayNowNum + bdNextNum) + "天就过生日了");
41                 else
42                     Console.WriteLine("您还差" + (intDay - intDayNow) + "天不到" + (intMonth - intMonthNow) + "个月总共" + (DaybdNum - DayNowNum) + "天就过生日了");
43             }
44             Console.WriteLine("您的出生日期为"+(bdDT .Year-age)+"年"+intMonth+"月"+intDay+"日");
45 
46             Console.ReadLine();
