只预设了dateTimePicker的值。

just preset the value of dateTimePicker.

感谢您回复adriancs，但是回复不起作用，它只增加3天的总停留时间，而不是 - 当应用程序启动时，它应显示当前日期加上出发日期的三天。


在你的回答中，出发日期始终保持在圣母院，并且不允许用户输入日期选择，

thanks for replying adriancs, but your reply does not work, it only adds 3 days to the total stay, instead of - When the application starts, it should be displaying the current date plus three days in the departure date.

In your answer the departure date stays the dame all the time and does not allow user to enter selection of date,
