1.實現效果
時鐘實時展示系統本機時間
2.業務場景
模擬時鐘
3.編碼實現
使用 .Net Core 3.1 創建名為 “Clock” 的WPF解決方案,解決方案中需要添加時鐘背景圖片,圖片如下:https://github.com/Abel13/Clock/blob/master/Clock/Assets/clock.png
3.1 主窗體 MainWindow.xaml
使用3個Border佈局時鐘的時針、分針、秒針,並給3個指針添加動畫,動畫說明如下:
- 時針每12個小時迴圈一圈(360°),每個小時旋轉30°(30°*12=360°);
- 分針每60分鐘迴圈一圈(360°),每分鐘旋轉6°(6°*60=360°);
- 秒針每60秒迴圈一圈(360°),每秒鐘旋轉6°(6°*60=360°),並且秒針旋轉6°有個輕微的擺動動畫。

3.2 MainWindow.xaml.cs
後臺代碼開啟三個指針動畫,並設置各指針動畫起始位置
using System;
using System.Windows;
using System.Windows.Input;
using System.Windows.Media.Animation;
namespace Clock
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
int now_hours = DateTime.Now.Hour > 12 ? (DateTime.Now.Hour - 12) : DateTime.Now.Hour;
int now_minutes = DateTime.Now.Minute;
int now_seconds = DateTime.Now.Second;
Storyboard seconds = (Storyboard)second.FindResource("sbseconds");
seconds.Begin();
seconds.Seek(new TimeSpan(0, 0, 0, now_seconds, 0));
Storyboard minutes = (Storyboard)minute.FindResource("sbminutes");
minutes.Begin();
minutes.Seek(new TimeSpan(0, 0, now_minutes, now_seconds, 0));
Storyboard hours = (Storyboard)hour.FindResource("sbhours");
hours.Begin();
hours.Seek(new TimeSpan(0, now_hours, now_minutes, now_seconds, 0));
}
private void Window_MouseDown(object sender, MouseButtonEventArgs e)
{
DragMove();
}
}
}

Design com WPF 大神的學習視頻:

5.代碼下載
源碼中實現了全部效果,大伙可以直接下載編譯運行;建議看大神視頻手敲一遍,加深學習印象;視頻中使用Blend佈局時鐘、設置動畫,類似PS(PhotoShop),設計界面很是方便的。
