试试我在google中找到的这个代码，应该可以解决这个问题：
DateTime now = DateTime.Now;
int age = now.Year - bday.Year;
if (now < bday.AddYears(age))
age--;
答案 1 :(得分：1)
使用javascript
function getAge(dateString) { //parameter date from form, should look like "03/21/1986"
var today = new Date();
var birthDate = new Date(dateString);
var age = today.getFullYear() - birthDate.getFullYear();
var m = today.getMonth() - birthDate.getMonth();
if (m < 0 || (m === 0 && today.getDate() < birthDate.getDate())) {
age--;
}
return age;
}
