如何随时更改时间观察时间？我通过每秒植入时间检查来尝试简单的事情，但这会减慢程序并不断挂断按钮。如何在不挂断程序的情况下完成这项工作？

您好，您可以使用调度程序计时器。以下是UWP中的示例实现：

using System;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;

namespace App1
{
    public sealed partial class MainPage : Page
    {
        private DispatcherTimer timer;
        private int counter = 0;

        public MainPage()
        {
            this.InitializeComponent();
            timer = new DispatcherTimer();

            Loaded += MainPage_Loaded;
        }

        private void MainPage_Loaded(object sender, RoutedEventArgs e)
        {
            timer.Interval = TimeSpan.FromSeconds(1.0);
            timer.Tick += Timer_Tick;
            timer.Start();
        }

        private void Timer_Tick(object sender, object e)
        {
            if (counter == 10)
            {
                //do operation in every 10 seconds
                counter = 0;
                //if you want to stop the timer use timer.Start()
            }
            else
            {
                counter++;
            }
        }
    }
}
