推荐答案

您可以将年份添加为

You can add years as

for (int i = 0; i <= 9; i++) {
    ddl.Items.Add(DateAndTime.Now.Year + 1);
}

要添加月份(如果年份是当前年份)

To add months, if the year is current year

for (int i = DateAndTime.Now.Month; i <= 12; i++) {
    ddl.Items.Add(DateAndTime.MonthName(i));
}

其他

else

for (int i = 1; i <= 12; i++) {
    ddl.Items.Add(DateAndTime.MonthName(i));
}
