c# - UWP 组在运行时有奇怪的行为
问题描述
我是 UWP 的 XAML 新手。所以我正在尝试使用 .XAML 制作 4 个组合框。当我尝试运行代码时,它会拉伸使 GUI 看起来很糟糕的组框。.XAML 中的什么可能导致这样的事情?
在设计期间,它看起来像:
当我在模拟器中运行代码时,它看起来像:

关于 UWP 应用程序的另一个问题是,您是否必须有一些特殊的东西才能运行在 Bin 文件夹中输出的 .exe?当尝试以管理员身份运行 .exe 时,它只会崩溃并出现未处理的 win32 异常。
解决方案
当我尝试运行代码时,它会拉伸使 GUI 看起来很糟糕的组框。.XAML 中的什么可能导致这样的事情?
您使用Margin
属性来控制 XAML 控件的位置,这将导致您看到的混乱布局。
请参阅布局文档以了解如何在 UWP 中使用 XAML 制作良好的布局。
例如,您可以简单地使用 Grid 控件将这些控件放在不同的行和列上。
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition></ColumnDefinition>
<ColumnDefinition></ColumnDefinition>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="4*"></RowDefinition>
<RowDefinition Height="4*"></RowDefinition>
<RowDefinition Height="*"></RowDefinition>
</Grid.RowDefinitions>
<ComboBox HorizontalAlignment="Center" Grid.Row="0" Grid.ColumnSpan="2" VerticalAlignment="Center" Height="42" Width="232"/>
<ListView x:Name="DatabaseInfo" Grid.Row="1" Grid.Column="0" Header="Database Info." BorderThickness="2" BorderBrush="Black" SelectionMode="None" FontFamily="Tahoma" >
<ListView.HeaderTemplate>
<DataTemplate>
<ListViewHeaderItem Content="{Binding}" Height="40" />
</DataTemplate>
</ListView.HeaderTemplate>
<StackPanel Width="230" Height="30" Orientation="Horizontal" >
<TextBlock Name="ServerNameDisplay" HorizontalAlignment="Left" Text="Server" Width="115" Height="25" />

</StackPanel>
<StackPanel Width="230" Height="30" Orientation="Horizontal" >
<TextBlock Name="DatabaseNameDisplay" HorizontalAlignment="Left" Text="Database" Width="115" Height="25" />

UWP 在沙盒中运行,它不同于经典的桌面应用程序。您不能直接双击“.exe”文件来启动它。当你在 Visual Studio 中编码时,你可以按F5下来启动它并调试它。如果已部署,您可以从 Windows 的“开始”菜单启动它。
温馨提示:下次请不要在一个帖子中发布多个问题。
