这是我需要帮助的地方 显示我通过 form1 填充的数组
displayMessage("Name: " + People[i].Firstname + People[i].Lastname + " BirthDate: " + People[i].Birthdate.Year + People[i].Birthdate.Day + People[i].Birthdate.Month + "\n\n");
//richTxtDisplay.AppendText(People[i].ToString());
//richTxtDisplay.AppendText(People[i].Firstname + People[i].Lastname + People[i].Birthdate + "\n");

我的班级是Person ..
public class Person
{
private string _firstname;
private string _lastname;
private DateTime _birthdate;
public Person(string firstname, string lastname, DateTime birthdate)
{
_firstname = firstname;
_lastname = lastname;
_birthdate = birthdate;
}
public string Firstname
{ get { return _firstname; } }
public string Lastname
{ get { return _lastname; } }
public DateTime Birthdate
{ get { return _birthdate; } }
public int getAge()
{
TimeSpan ts =
DateTime.Now - _birthdate;
int year = (int)ts.TotalDays / 365;
return year;
}
public int daysUntillBirthDate()
{
int age = getAge();
DateTime proximobirthday = _birthdate.AddYears(age + 1);
TimeSpan ts = proximobirthday - DateTime.Now;
return ts.Days;
}
}
我已经用名字、姓氏和出生日期标记了显示数组的位置。我没有任何错误，它不会显示任何内容，我可以单击按钮多次显示，它不会破坏我的代码。我不记得要使用哪种格式豁免，但 try catch 应该足够好。
