如何在WP7 BGM中循环播放音乐？

发布于 2024-11-09 15:05:13 字数 568 浏览 5 评论 0原文

private void button1_Click(object sender, RoutedEventArgs e)
{
    MediaElement Lala = 
        ((MediaElement)App.Current.Resources["backgroundMusic"]).Stop();

    if (Lala == true)
    {
        ((MediaElement)App.Current.Resources["backgroundMusic"]).Play();
    }

为什么不循环？

或者还有其他方法让我的BGM循环播放吗？

这是我在 App.xaml 中编写的内容，它可以工作，但不确定如何循环它：

<Application.Resources>
    <MediaElement x:Name="backgroundMusic" Source="Nyan.mp3" AutoPlay="True" Volume="1" />
</Application.Resources>

原文

private void button1_Click(object sender, RoutedEventArgs e)
{
    MediaElement Lala = 
        ((MediaElement)App.Current.Resources["backgroundMusic"]).Stop();

    if (Lala == true)
    {
        ((MediaElement)App.Current.Resources["backgroundMusic"]).Play();
    }

Why won't it loop?

Or is there any other way to make my BGM loop?

This is what I wrote in the App.xaml and it works, but not sure how to loop it:

<Application.Resources>
    <MediaElement x:Name="backgroundMusic" Source="Nyan.mp3" AutoPlay="True" Volume="1" />
</Application.Resources>

由于它尚未得到完全解答 -

您正在寻找 MediaElement 在停止循环时自行循环。你的代码没有这样做。相反，您的代码是 1）单击按钮时停止音乐。下一行代码：if (Lala == true) 是媒体元素上的 bool。

即使代码完全在 XAML 中，自动循环的简单方法也是插入 MediaEnded="" 代码。这样，您可以创建一个事件处理程序来指定媒体结束时要执行的操作。因此，在您的示例中，您的 XAML 将如下所示：

 <MediaElement x:Name="backgroundMusic" Source="Nyan.mp3" AutoPlay="True" Volume="1" MediaEnded="DoThisWhenMediaEnds" />

您的 c# 将如下所示：

 private void DoThisWhenMediaEnds(object sender, RoutedEventArgs e)
 {
    //what to do when the media has ended. In this case:
    backgroundMusic.Play();
 }

好了！你将拥有你所能管理的所有 Nyan 善良。

Since it's not been fully answered --

you're looking for the MediaElement to loop itself when it stops its cycle. Your code is not doing that. Instead your code is 1) Stopping the music when the button is clicked. The next line of code: if (Lala == true) is a bool on a media element.

The simple way to autoloop, even if you have the code entirely in XAML alone, is to insert the MediaEnded="" code. With this, you create an event handler to specify what to do when the media has ended. So in your example, your XAML will look like this:

 <MediaElement x:Name="backgroundMusic" Source="Nyan.mp3" AutoPlay="True" Volume="1" MediaEnded="DoThisWhenMediaEnds" />

and your c# will look like this:

 private void DoThisWhenMediaEnds(object sender, RoutedEventArgs e)
 {
    //what to do when the media has ended. In this case:
    backgroundMusic.Play();
 }

There you go! You will have all the Nyan goodness you can manage.
