Win10的UWP之进度条

关于UWP的进度条的处理的方案有两种方案
我们新建一个项目，然后处理的界面如下的代码

<Grid.RowDefinitions>            <RowDefinition Height="Auto"/>            <RowDefinition Height="Auto"/>            <RowDefinition Height="Auto"/>            <RowDefinition Height="Auto"/>            <RowDefinition Height="Auto"/>            <RowDefinition Height="*"/>        </Grid.RowDefinitions>            <TextBlock Text="选择" FontSize="20"                       Grid.Row="0"                       HorizontalAlignment="Center"/>            <RadioButton Content="Determinate类型"                          Height="71"                          Name="radionButton1"                         GroupName="Type"                         Grid.Row="1"                         HorizontalAlignment="Center"/>            <RadioButton Content="Indeterminate类型"                         Height="71"                         Name="radioButton2"                         GroupName="Type"                         IsChecked="True"                         Grid.Row="2"                         HorizontalAlignment="Center"/>            <Button Content="启动ProgressBar"                     Height="72"                    x:Name="Begin"                    Click="Begin_Click"                    Grid.Row="3"                    HorizontalAlignment="Center"/>            <Button Content="取消ProgressBar"                    Height="72"                    x:Name="Cancel"                    Click="Cancel_Click"                    Grid.Row="4"                    HorizontalAlignment="Center"                    VerticalAlignment="Center"/>        <ProgressBar x:Name="ProgressBar" IsIndeterminate="True"                         Grid.Row="5"                     Height="24"/>

然后我们再来处理下界面的后台代码

public MainPage()        {            this.InitializeComponent();            //初始化界面时，设置进度条不可见            ProgressBar.Visibility = Visibility.Collapsed;        }        private void Begin_Click(object sender, RoutedEventArgs e)        {            //启动进度条，并可以显示状态            ProgressBar.Visibility = Visibility.Visible;            if (radionButton1.IsChecked==true)            {                //设置进度条的模式为不重复状态                ProgressBar.IsIndeterminate = false;                //启用定时器，再每下一秒改变原来的状态                DispatcherTimer timer = new DispatcherTimer();                timer.Interval = TimeSpan.FromSeconds(1);                timer.Tick += timer_Tick;                timer.Start();            }            else            {                ProgressBar.Value = 0;                ProgressBar.IsIndeterminate = true;            }        }        async void timer_Tick(object sender,object e)        {            if (ProgressBar.Value<100)            {                ProgressBar.Value += 10;            }            else            {                (sender as DispatcherTimer).Tick -= timer_Tick;                (sender as DispatcherTimer).Stop();                await new MessageDialog("进度100%").ShowAsync();            }        }        private void Cancel_Click(object sender, RoutedEventArgs e)        {            ProgressBar.Visibility = Visibility.Collapsed;        }

我们来看一下运行的效果吧

这是模拟了手机的界面运行的结果
