<Window x:Class="WpfApp1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Transparent Text" Height="450" Width="800">
    <Grid>
        <TextBlock x:Name="transparentText" Text="Hello, World!" FontSize="24" FontWeight="Bold" HorizontalAlignment="Center" VerticalAlignment="Center"/>
    </Grid>
</Window>

using System.Windows;
using System.Windows.Media;

namespace WpfApp1
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            // 设置文本的背景和前景颜色
            Brush backgroundBrush = new SolidColorBrush(Color.FromArgb(0, 0, 0, 0)); // 设置为完全透明的背景色
            Brush foregroundBrush = Brushes.Black; // 设置前景色为黑色

            transparentText.Background = backgroundBrush;
            transparentText.Foreground = foregroundBrush;
        }
    }
}
