windows phone 7 ..播放或暂停音乐

Question

我正在开发Windows Phone 7中的游戏。我想在主页上添加一个允许在图像之间切换的按钮。

我写了下面的代码，但没有工作

int key = 1;

        switch (key)
        { 
            case 1:
                 var brush = new ImageBrush();
            BitmapImage image = new BitmapImage(new Uri(@"Assets/small/misc/music pause button.png", UriKind.Relative));
            brush.ImageSource = image;
            music.Background = brush;
            key=0;

                break;

            case 0:
                 var brush2 = new ImageBrush();
            BitmapImage image2 = new BitmapImage(new Uri(@"Assets/small/misc/music pause button.png", UriKind.Relative));
            brush2.ImageSource = image2;
            music.Background = brush2;
            key = 1;

                break;

        }

使用togglebutton

解决了这个问题

在xaml中有切换按钮控件    <ToggleButton Name="tog" Margin="555,358,0,7" IsChecked="{x:Null}" Checked="tog_Checked" Unchecked="tog_Unchecked" Background="{x:Null}" BorderBrush="{x:Null}" BorderThickness="0" IsThreeState="False" HorizontalAlignment="Left" Width="123"></ToggleButton>

现在在事件处理程序上添加代码：

    private void tog_Checked(object sender, RoutedEventArgs e)
    {

        tog.Background = brush;
        togkey = 1;
        System.Diagnostics.Debug.WriteLine("1");
    }

    private void tog_Unchecked(object sender, RoutedEventArgs e)
    {

        tog.Background = null;
        togkey = 0;
        System.Diagnostics.Debug.WriteLine("0");
    }
