啟動應用程序時刪除黑屏

Question

我創建了一個C＃WPF應用程序。 在這種情況下，我的UI組件有限（標簽，MediaElement，圖像源（4））。 我正在用最大化的窗口加載我的應用程序。 當我啟動exe時，黑屏顯示一秒鍾，然后出現實際的UI。

我設置了一個屬性，即AllowsTranparency = True。 它解決了上述問題，但要花一個新的錢，即，如果將此屬性設置為true，則MediaElement中播放的視頻會滯后很多。

因此，排除了此解決方案。

App.xaml中：

<Application x:Class="MainWin.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:local="clr-namespace:MainWin"
             Startup="MainWindow.xaml">
</Application>

主Window.xaml：

<Window x:Class="MainWin.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        xmlns:local="clr-namespace:MainWin"
        mc:Ignorable="d"
        Title="" Width="width" Height="height"
        Loaded="Window_Load"
        WindowState="Maximized"
        WindowStartupLocation="CenterScreen"
        WindowStyle="None"
        AllowsTransparency="False"
        Topmost="True"
        Opacity="0">
    <Grid x:Name="grid" Width="0" Height="0">
        <MediaElement x:Name="name" Opacity="0" Visibility="Visible" LoadedBehavior="Play" MediaEnded="Media_Ended" Source="loc" Margin="0,0,0,0"/>
        <Image Name="name" RenderOptions.BitmapScalingMode="HighQuality" Source="" Visibility="Hidden" Width="1400" Height="660" Opacity="0"/>
        <Image Name="name" RenderOptions.BitmapScalingMode="HighQuality" Source="" Stretch="Fill" Visibility="Hidden" Width="20" Height="12" Opacity="0"/>

        <Image Name="name" RenderOptions.BitmapScalingMode="HighQuality" Source="loc" Stretch="Fill" Visibility="Hidden" Width="0" Height="12" Opacity="0"/>
        <Image Name="name" RenderOptions.BitmapScalingMode="HighQuality" Source="loc" Stretch="Fill" Visibility="Hidden" Width="20" Height="12" Opacity="0"/>
        <Label x:Name="name" Content="text" Width="712" HorizontalAlignment="Center" HorizontalContentAlignment="Center" Visibility="Hidden" Foreground="White" FontSize="font" FontFamily="font" FontWeight="Regular" Opacity="0"/>
        <Label x:Name="name" Content="text" Width="1248" HorizontalAlignment="Center" HorizontalContentAlignment="Center" Foreground="White" FontSize="font" Visibility="Hidden" FontFamily="font"  FontWeight="Regular" Opacity="0"/>
        <Label x:Name="name" Content="text" Width="710" HorizontalAlignment="Center" HorizontalContentAlignment="Center" Visibility="Hidden" Foreground="White" FontSize="font" FontFamily="font"  FontWeight="Regular" Opacity="0"/>
        <Label x:Name="name" Content="text" Width="710"  HorizontalAlignment="Center" HorizontalContentAlignment="Center" Visibility="Hidden" Foreground="White" FontSize="font" FontFamily="font"  FontWeight="Regular" Opacity="0"/>
    </Grid>
</Window>

我想刪除應用程序啟動時出現的黑屏。

Answer 1

更改Background="Color you want"或“透明” Window標簽。
