Question

在我的工具中，我在运行时创建了一个TimePicker XAML控件，但是我在为TimeChanged事件苦苦挣扎。

// TimePicker
TimePicker timePicker = new TimePicker
{
    Margin = new Thickness(0, 0, 0, 7),
    HorizontalAlignment = HorizontalAlignment.Center,
    VerticalAlignment = VerticalAlignment.Bottom,
    RequestedTheme = ElementTheme.Dark,
    Name = "Schedule_" + lightnumber + "_timepicker",
    ClockIdentifier = "24HourClock",
    Time = TimeSpan.Parse(hue_schedules_localtime),
};
hueGrid.Children.Add(timePicker);
timePicker.TimeChanged += new TimePickerValueChangedEventArgs(Schedule_TimeChange);

private void Schedule_TimeChange(string sender, TimePickerValueChangedEventArgs e)
        {

        }

我总是收到此错误消息“错误CS1729'TimePickerValueChangedEventArgs'不包含带有1个参数的构造函数”

不幸的是，我在互联网上找不到c＃示例。

有人可以帮我解决这个问题。

您在订阅事件代码时出错，您应将方法/本地函数/ lambda添加为订户，而您尝试将TimePickerValueChangedEventArgs实例添加为订户，而TimePickerValueChangedEventArgs构造函数却没有。 t接受一个参数，所以这就是为什么出现TimePickerValueChangedEventArgs does not contain a constructor that takes 1 arguments错误的原因。固定代码：

timePicker.TimeChanged += Schedule_TimeChange;

private void Schedule_TimeChange(object sender, TimePickerValueChangedEventArgs e)
{

}

如何在C＃中构建TimePicker.TimeChanged事件？
