If you want to do something when selected date changes, the Calendar control has a SelectedDatesChangedevent. Add an event handler method for this event.
如果您想在选定日期更改时执行某些操作，日历控件有一个SelectedDatesChanged事件。为此事件添加事件处理程序方法。
XAML:
XAML：
<Calendar SelectedDatesChanged="Calendar_OnSelectedDatesChanged"/>
Code behind:
后面的代码：
private void Calendar_OnSelectedDatesChanged(object sender, SelectionChangedEventArgs e)
{
}
It sounds like your question might be around object scope in C#. Needs further explanation
听起来您的问题可能与 C# 中的对象范围有关。需要进一步解释

You might want to use a DatePickerinstead of a Calendar and listen for the following event SelectedDateChanged.
您可能希望使用DatePicker而不是 Calendar 并侦听以下事件 SelectedDateChanged。
You could try and listen for the DisplayDateChangedevent for the Calendar class and do something when the date changes.
您可以尝试侦听Calendar 类的DisplayDateChanged事件，并在日期更改时执行某些操作。
