解决方案
在这里试试这个：
在你的ButtonOnClick活动中
DateTime bday = Convert.ToDateTime（txtDOB.Text）;
今日DateTime = DateTime.Today;
int age = today.Year - bday.Year;
if （bday > today.AddYears（-age））age--;
txtAge.Text = age.ToString（）;
希望有帮助

这很痛苦，不是吗？
见这里：使用Age：它与TimeSpan不同！ [ ^ ]
嗯，这个答案可能很多！是的，dob的年龄计算可以有多种方式。绝对取决于您从用户输入的格式。最简单的可能是：
var today = float .Parse（DateTime.Now.ToString（ yyyy.MMdd））;
var inputDob = float .Parse（dateOfBirth.ToString（ yyyy.MMdd））;
var age =（ int ）（今天 - inputDob）;
哪里 dateOfBirth 是你的输入。

Here try this:
In your Button'sOnClickevent
DateTime bday = Convert.ToDateTime(txtDOB.Text); DateTime today = DateTime.Today; int age = today.Year - bday.Year; if (bday > today.AddYears(-age)) age--; txtAge.Text = age.ToString();
Hope it helps

It's a pain, isn't it?
See here: Working with Age: it's not the same as a TimeSpan![^]
Well,this answer could be numerous! Yes, age calculation from dob could be a number of ways. Absolutely that depends on which format you are taking input from user. The simplest one could be like:
var today = float.Parse(DateTime.Now.ToString("yyyy.MMdd")); var inputDob = float.Parse(dateOfBirth.ToString("yyyy.MMdd")); var age = (int)(today - inputDob);
Where dateOfBirth is your input.
