Question

我使用this question的答案作为构建我正在构建的应用程序的基础。

在设计模式下看起来都很好，我得到以下结果：

但是在运行时我的内容比我的内容有很大差距，在这种情况下是MediaElement：

我的MainWindow的代码是：

<local:MyWindow x:Class="DebriefSuite.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:DebriefSuite"        
        Height="439.091" Width="600" 
        Style="{DynamicResource MyWindowStyle}"
        WindowStyle="None">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="6*"/>
            <RowDefinition Height="1*"/>
        </Grid.RowDefinitions>
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="6*"/>
            <ColumnDefinition Width="2*"/>
        </Grid.ColumnDefinitions>
        <Grid Grid.Row="0" Grid.Column="0">

        </Grid>        
    </Grid>
</local:MyWindow>

我的App.xaml中的代码资源代码与链接的问题相同，但无论如何我都会包含它：

有人能指出我正确的方向，这种格式差异来自何处？

非常感谢。

你看到这个盒子填满了设计中更大的空间，因为这是MediaElement可以占用的最大尺寸。但是您的实际图像小于为MediaElement控件分配的大小，因此它在运行时看起来更小。

因此，如果您希望图像填满空间，请尝试根据需要使用其stretch属性。例如，请参阅此处：MediaElement.Stretch Property
