Question

CS0029无法将类型“System.Threading.Timer”隐式转换为“Windows.UI.Xaml.DispatcherTimer”
这是我收到的错误代码，我相信这是无法构建项目的原因。我的教授主持了一次变焦 session 并制作了一个youtube视频，这是他写的一些代码，我们结束了。

namespace DataCollector
{
/// <summary>
/// An empty page that can be used on its own or navigated to within a Frame.
/// </summary>
public sealed partial class MainPage : Page
{

    private DispatcherTimer timer;
    MeasureLengthDevice measurementDevice = null;
    MainViewData displayData = new MainViewData();

    Frame frame = null;
    MainPage page = null;

    public MainPage()
    {
        this.InitializeComponent();
        timer = new Timer(Timer_Tick, null, (int)TimeSpan.FromSeconds(1).TotalMilliseconds, 
(int)TimeSpan.FromSeconds(15).TotalMilliseconds);
        measurementDevice = new MeasureLengthDevice();

        displayData = new MainViewData
        {
            Measurement = measurementDevice.ToString(),
            History = measurementDevice.History
        };

    }

    private void Button_Click(object sender, RoutedEventArgs e)
    {
        frame = (Frame)Window.Current.Content;
        page = (MainPage)frame.Content;
        measure.Text = measurementDevice.Measurement.ToString();
        measureHistory.Text = measurementDevice.History;
    }

    private async void Timer_Tick(object state)
    {
        await CoreApplication.MainView.CoreWindow.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, 
() =>
        {
            if (page != null)
            {
                page.measure.Text = measurementDevice.Measurement.ToString();
            }
            displayData.History = measurementDevice.History;
        });
    }
}
}

该代码显然是错误的，没有更多上下文就无法修复它。但是，您真的应该问您的教授，为什么它不起作用，而不是在Stack Overflow上发布您的问题。
