第一步,用WPF (.NET Framework),添加個TextBox,簡單設置屬性。this
第二步,貼代碼spa
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; 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; using System.Windows.Threading; //添加Threading類 namespace ClockSample { public partial class MainWindow : Window { public MainWindow() { InitializeComponent(); DispatcherTimer ClockOut = new DispatcherTimer(); // 類的實例化--設置對象(實例成員) ClockOut.Interval = TimeSpan.FromSeconds(1); //設置屬性 ClockOut.Tick += ClockOut_Tick;// 連接事件處理器 ClockOut.Start(); } private void ClockOut_Tick(object sender, EventArgs e) { this.ClockBox.Text = DateTime.Now.ToString(); } } }
心得:初識類的使用方法。 對象
