通过单击按钮以编程方式停止AxWindowsMediaPlayer

Question

如何在单击按钮时手动停止AxWindowsMediaPlayer？我正在WPF中开发一个应用程序，并使用VS 2015。

<WindowsFormsHost x:Name="winhost" HorizontalAlignment="Stretch" VerticalAlignment="Center" Background="Transparent" Visibility="Hidden">
    <ax:AxWindowsMediaPlayer x:Name="axwmp" /> 
</WindowsFormsHost>

如果按钮上有命令绑定，或者以编程方式查看按钮单击事件，则可以执行以下命令：

axWindowsMediaPlayerObject.Ctlcontrols.stop();

这是我的代码，我是如何尝试的：

WPF - MainWindow

<Grid>
    <Grid.RowDefinitions>
        <RowDefinition />
        <RowDefinition />
    </Grid.RowDefinitions>

    <Button Grid.Row="0" Click="ButtonBase_OnClick">Test</Button>

    <WindowsFormsHost Grid.Row="1" x:Name="winhost" HorizontalAlignment="Stretch" VerticalAlignment="Center" Background="Transparent">
        <ax:AxWindowsMediaPlayer x:Name="axwmp" />
    </WindowsFormsHost>
</Grid>

代码在中的应用

public partial class MainWindow : Window
{
    private AxWindowsMediaPlayer mPlayer;

    public MainWindow()
    {
        InitializeComponent();
        mPlayer = axwmp;
        mPlayer.BeginInit();
        mPlayer.EndInit();
        mPlayer.Ctlenabled = true;
        mPlayer.URL = @"http://www.mediacollege.com/audio/tone/files/100Hz_44100Hz_16bit_30sec.mp3";
        mPlayer.Ctlcontrols.play();
    }

    private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
    {
        mPlayer.Ctlcontrols.stop();
    }
}

顺便说一句，您需要将MediaPlayer.exe输出到您的exe。
