例外

示例

在美国，驾驶执照不能颁发给16岁以下的人。 以下示例显示一个人必须出生的最新日期，以便合法地颁发驾驶执照。

const int minimumAge = 16;
DateTimeOffset dateToday = DateTimeOffset.Now;
DateTimeOffset latestBirthday = dateToday.AddYears(-1 * minimumAge);
Console.WriteLine("To possess a driver's license, you must have been born on or before {0:d}.",
                  latestBirthday);

let minimumAge = 16
let dateToday = DateTimeOffset.Now
let latestBirthday = dateToday.AddYears(-1 * minimumAge)
printfn $"To possess a driver's license, you must have been born on or before {latestBirthday:d}."

Const minimumAge As Integer = 16
Dim dateToday As DateTimeOffset = DateTimeOffset.Now
Dim latestBirthday As DateTimeOffset = dateToday.AddYears(-1 * minimumAge)
Console.WriteLine("To possess a driver's license, you must have been born on or before {0:d}.", _
                  latestBirthday)

注解

与将单个时间间隔单位（如分钟或天）添加到日期和时间值的大多数其他方法不同， AddYears 无法添加年份的小数部分。 若要向对象添加由其他时间单位组成的时间（除了向对象添加年份 DateTimeOffset ），请使用 Add 该方法。
