2）CSharp processing task events

    private void BtnOffTask_Click(object sender, RoutedEventArgs e)
    {
        if (tokenSource == null) return;
        tokenSource.Cancel();
        Loading.SetIsShow(btnLoadingTask, false);
    }
    private CancellationTokenSource tokenSource;
    /// <summary>
    /// 此处演示关闭loading停止任务
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    private void LoadingTask_Click(object sender, RoutedEventArgs e)
    {
        tokenSource = new CancellationTokenSource();
        var cancellationToken = tokenSource.Token;

        var task = new Task(() =>
        {
            for (int i = 0; i < 10; i++)
            {
                //这里做自己的事情
                if (tokenSource.IsCancellationRequested)
                    return;
                Thread.Sleep(1000);
            }
        }, cancellationToken);
        task.ContinueWith(previousTask =>
        {
            if (tokenSource.IsCancellationRequested)
                return;
            Loading.SetIsShow(btnLoadingTask, false);
        }, TaskScheduler.FromCurrentSynchronizationContext());
        Loading.SetIsShow(btnLoadingTask, true);
        task.Start();
    }
    private void BtnLoading_Click(object sender, RoutedEventArgs e)
    {
        var task = new Task(() => { Thread.Sleep(5000); });
        task.ContinueWith(previousTask => { Loading.SetIsShow(btnLoading, false); }, TaskScheduler.FromCurrentSynchronizationContext());
        Loading.SetIsShow(btnLoading, true);
        task.Start();
    }
