本文将介绍如何利用Silverlight技术创建一个简单的交互式用户界面应用，通过使用多种.NET框架组件，如Windows Presentation Foundation (WPF)控件，实现用户与应用程序之间的交互。示例包括使用ListBox和TextBox进行数据展示和输入操作。

using System; using System.Collections.Generic; using System.Linq; using System.Net; using System.Windows; using System.Windows.Controls; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Animation; using System.Windows.Shapes; namespace FirstSilverlightApplication { public partial class MainPage : UserControl { public MainPage() { InitializeComponent(); } private void listBox1_SelectionChanged(object sender, SelectionChangedEventArgs e) { ListBoxItem theItem = listBox1.SelectedItem as ListBoxItem; textBox1.Text = theItem.Content.ToString(); } } }
<UserControl x:Class="FirstSilverlightApplication.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="400" xmlns:sdk="http://schemas.microsoft.com/winfx/2006/xaml/presentation/sdk"> <Grid x:Name="LayoutRoot" Background="White"> <ListBox Height="154" HorizontalAlignment="Left" Margin="59,12,0,0" Name="listBox1" VerticalAlignment="Top" Width="239" ItemsSource="{Binding}" SelectionChanged="listBox1_SelectionChanged"> <ListBoxItem Content="List1" /> <ListBoxItem Content="List2" /> <ListBoxItem Content="List3" /> </ListBox> <TextBox Height="23" HorizontalAlignment="Left" Margin="59,192,0,0" Name="textBox1" VerticalAlignment="Top" Width="239" /> </Grid> </UserControl>
