Question

我想在我的应用中播放mp3音频，但什么也没发生我的代码就是这个

XAML：

<Page
    x:Class="SunnahForKids.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:SunnahForKids"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Grid Background="Black">

        <StackPanel Width="900" Height="700" HorizontalAlignment="Center">
            <MediaElement HorizontalAlignment="Left" Name="a" AutoPlay="False" Source="azan.mp3" Height="100" Margin="451,299,0,0" VerticalAlignment="Top" Width="100" Volume="100"/>

            <Button Content="Button" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0,0,676,0" Height="189" Click="Button_Click"/>
        </StackPanel>

            a.Play();

        }


    }

我正在努力奋斗2天需要帮助。我也点了这个链接MediaElement in WinRT / Win8 does not work at all 更新我的驱动程序，但它是最新的。英特尔R（Q35）快速芯片组家族（微软公司WDDM-1.0）中的显示驱动程序请让我离开这里..

我尝试了你的代码并且代码有效，所以发生了一些奇怪的事情。我会尝试听取链接中提到的事件（例如，对于寻找代码示例的开发人员，进一步向下）。

检查计算机上的事件日志（Windows =＆gt;应用程序），如果您错过了Windows的更新，并检查该mp3是否会播放。

收听MediaFailed事件（建议您在文档中进行操作），看看是否可以在那里获取一些信息。Code from msdn:

private void videoMediaElement_MediaFailed(object sender, ExceptionRoutedEventArgs e)
{
    // Check the event arguments => e

    // get HRESULT from event args 
    string hr = GetHresultFromErrorMessage(e);

    // Handle media failed event appropriately 
}

private string GetHresultFromErrorMessage(ExceptionRoutedEventArgs e)
{
    String hr = String.Empty;
    String token = "HRESULT - ";
    const int hrLength = 10;     // eg "0xFFFFFFFF"

    int tokenPos = e.ErrorMessage.IndexOf(token, StringComparison.Ordinal);
    if (tokenPos != -1)
    {
        hr = e.ErrorMessage.Substring(tokenPos + token.Length, hrLength);
    }

    return hr;
}

媒体元素不在Windows应用商店中播放音频
