Question

我有我的标签

<Label Content="$500"   Height="113" HorizontalAlignment="Left" Margin="12,21,0,0"
     Name="label1" VerticalAlignment="Top" BorderBrush="Black" AllowDrop="False"
     Panel.ZIndex="1" Width="350" Foreground="#FFEFEFEF" FontFamily="Arial"
     FontSize="100">

我试过这个：

label1.Width = System.Windows.SystemParameters.PrimaryScreenWidth;

但它不起作用。如何让标签的宽度为PrimaryScreenWidth？

以下是我的完整代码：

<Window x:Class="Game.Player1Screen"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Player1Screen" Height="300" Width="300">
    <Grid>

        <Label Content="$500"   Height="113" HorizontalAlignment="Left" Margin="12,21,0,0" Name="label1" VerticalAlignment="Top" BorderBrush="Black" AllowDrop="False" Panel.ZIndex="1" Width="{x:Static SystemParameters.PrimaryScreenWidth}" Foreground="#FFEFEFEF" FontFamily="Arial" FontSize="100">

            <Label.LayoutTransform>

                <RotateTransform Angle="270"/>

            </Label.LayoutTransform>

        </Label>

        <ProgressBar Name="ProgressBarTimer" Panel.ZIndex="0" Orientation="Horizontal" Foreground="Blue" Background="Black" MouseLeftButtonDown="ProgressBarTimer_MouseLeftButtonDown"
Value="0" HorizontalAlignment="Left" Maximum="100" VerticalAlignment="Top" Height="{x:Static SystemParameters.PrimaryScreenHeight}" Width="{x:Static SystemParameters.PrimaryScreenWidth}">
        </ProgressBar>
          </Grid>
</Window>

你做了什么会有用，或者你可以在XAML中设置它：

<Label Width="{x:Static SystemParameters.PrimaryScreenWidth}" />

但是，标签的宽度（ActualWidth）将受其所在容器的约束 - 无论Width设置为何种。

将wpf标签调整为主屏幕宽度
