试试这个样本并使其适应你的表格：

Try this sample and adapt it to your form:

using System;
public class Program
{
	public static void Main()
	{
		//DateTime dob = dateTimePicker1.Value; // assuming dateTimePicker1 is used
		DateTime dob = new DateTime(1995, 2, 10);
		DateTime today = DateTime.Today;
		int age = today.Year - dob.Year;
		if (dob.AddYears(age) > today)
		{
			age--;
		}
		Console.WriteLine(age);
	}
}

参考： DateTimePicker.Value Property [ ^ ]
