asp.net根据生日计算年龄（具体到年月天）

private string getAge(string bornDate)

{

DateTime b = DateTime.Parse(bornDate);

int a2 = DateTime.Now.Year;

int b2 = b.Year;

int a3 = DateTime.Now.Month;

int b3 = b.Month;

int a4 = DateTime.Now.Day;

int b4 = b.Day;

int aa = (a2 - 1900) * 365 + a3 * 30 + a4;

int bb = (b2 - 1900) * 365 + b3 * 30 + b4;

int cc = aa - bb; //天数

int dd = (int)Math.Floor(Convert.ToDouble(cc / 365));

int days = cc - dd * 365;

int ee = days / 30;

int day = days - ee * 30;

return dd.ToString() + "岁 零" + ee.ToString() + "个月 零"+day+"天";

}
