【问题描述】:
我可能很累,但是为什么会抛出异常:
this.SomeDatePicker.SelectedDate = DateTime.Now.Date;
同样的情况发生在:
this.SomeDatePicker.SelectedDate = DateTime.Now;
错误信息是:
System.ArgumentOutOfRangeException was unhandled
Message=SelectedDate value is not valid.
Parameter name: d
Source=PresentationFramework
ParamName=d

您确定日期时间格式吗?我的意思是如果 your
DateTime.Now对应于分配给控件的那个? -
