最小年龄验证GUI c#

我要验证一个顾客至少25岁，以便租车。我相信我有正确的代码来计算客户类中的年龄，但它实际上并没有在应用

的代码中验证它。

代码来自customer.cs

 public int Age
    {
        get
        {
            // Get today's date
            DateTime currDate = DateTime.Now;
            // Get the difference in years
            int age = currDate.Year - birthdayPicker.Year;
            // Subtract another year if we're before the
            // birth day in the current year
            if (currDate.Month < birthdayPicker.Month || (currDate.Month == birthdayPicker.Month && currDate.Day < birthdayPicker.Day))
                age--;
            return age;
        }
    }

来自form .cs的代码(仍然在应用按钮上工作，但在我继续之前试图验证年龄)

private void applyButton_Click(object sender, EventArgs e)
    {
        if (myCust.Age >= (25))
        {
            maketextbox.Text = myVehicle.Make;
            modelTextbox.Text = myVehicle.Model;
            yearTextbox.Text = Convert.ToString(myVehicle.Year);
            vinTextbox.Text = Convert.ToString(myVehicle.Vin);
            MessageBox.Show("Congratulations, you have been approved to rent a car!");
        }
        else
        {
            MessageBox.Show("You are not old enough to rent a car.");
        }

 // Subtract another year if we're before the
 // birth day in the current year
 if (currDate.Month < birthdayPicker.Month || (currDate.Month >= birthdayPicker.Month && currDate.Day < birthdayPicker.Day))
            age--;
