我想以编程方式在屏幕右下方放置一个按钮。按钮应放置在屏幕高度和宽度的25%处(右下角)。如何以编程方式完成?
var displayInformation = DisplayInformation.GetForCurrentView();
ScreenHeight= (int)displayInformation.ScreenHeightInRawPixels;//1080
ScreenWidth= (int)displayInformation.ScreenWidthInRawPixels;//1920
<Button x:Name="btnTest" VerticalAlignment="Bottom">

根据您的评论,您需要距离右下角的距离。您可以通过设置按钮的边距并设置对齐来实现这一点 要根据应用程序/页面大小设置边距,可以使用以下代码段:
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
this.SizeChanged += MainPage_SizeChanged;
}
private void MainPage_SizeChanged(object sender, SizeChangedEventArgs e)
{
var height = this.ActualHeight;
var width = this.ActualWidth;
btnTest.Margin = new Thickness(0, 0, 0.25 * width, 0.25 * height);
}
}
您可以在MainPage_SizeChanged
:
btnTest.VerticalAlignment = VerticalAlignment.Bottom;
btnTest.HorizontalAlignment = HorizontalAlignment.Right;
另一种选择是在xaml中设置对齐:
<Button x:Name="btnTest" Content="Test" VerticalAlignment="Bottom" HorizontalAlignment="Right"/>
