this.DragMove();
}
private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
//UI异步更新
this.Dispatcher.Invoke(DispatcherPriority.Normal, (Action)(() =>
{
//秒针转动,秒针绕一圈360度,共60秒,所以1秒转动6度
secondPointer.Angle = DateTime.Now.Second * 6;
//分针转动,分针绕一圈360度,共60分,所以1分转动6度
minutePointer.Angle = DateTime.Now.Minute * 6;
//时针转动,时针绕一圈360度,共12时,所以1时转动30度。
//另外同一个小时内,随着分钟数的变化(绕一圈60分钟),时针也在缓慢变化(转动30度,30/60=0.5)
hourPointer.Angle = (DateTime.Now.Hour * 30)+ (DateTime.Now.Minute * 0.5);
//更新时间值
this.labTime.Content = DateTime.Now.ToString("HH:mm:ss");
}));
}
}
}
3、编辑MainWindow.xaml.CS文件,
对后台逻辑进行定制,代码如下:
-
using System;
using System.Collections.Generic;
-
using System.Linq;
using System.Text;
-
using System.Windows;
using System.Windows.Controls;
-
using System.Windows.Data;
using System.Windows.Documents;
-
using System.Windows.Input;
using System.Windows.Media;
-
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
-
using System.Windows.Shapes;
namespace WpfClock
