如何计算c#中dob的年龄

Question

   private void button1_Click(object sender, EventArgs e)
    {
        DateTime dob = new DateTime();
        textBox1.Text = dob.ToString();
        int age;
        age = Convert.ToInt32(textbox2.Text);
        age = DateTime.Now.Year - dob.Year;
        if (DateTime.Now.DayOfYear < dob.DayOfYear)
            age = age - 1;

    }

如何从dob中剔除年龄.这是我的形式.请给我一些想法

Answer 1

DateTime today = DateTime.Today;

int age = today.Year - bday.Year;

if (bday > today.AddYears(-age))
 age--;

Answer 2

您可以使用TimeSpan计算它,如:

DateTime dob = .....
DateTime Today = DateTime.Now;
TimeSpan ts = Today - dob;
DateTime Age = DateTime.MinValue + ts;


// note: MinValue is 1/1/1 so we have to subtract...
int Years = Age.Year - 1;
int Months = Age.Month - 1;
int Days = Age.Day - 1;
