动态加载XAML文件（2）

本文主要是介绍动态加载XAML文件（2），希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

C#代码部分

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;
using System.Threading;namespace SilverlightApplication1
{public partial class MainPage : UserControl{public MainPage(){InitializeComponent();this.Loaded += new RoutedEventHandler(MainPage_Loaded);}void MainPage_Loaded(object sender, RoutedEventArgs e){WebClient _wc = new WebClient();_wc.DownloadProgressChanged += new DownloadProgressChangedEventHandler(_wc_DownloadProgressChanged);_wc.OpenReadCompleted += new OpenReadCompletedEventHandler(_wc_OpenReadCompleted);_wc.OpenReadAsync(new Uri("SilverlightApplication2.xap", UriKind.Relative));}void _wc_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e){_progress1.Text = e.ProgressPercentage.ToString() + "%";if (e.ProgressPercentage == 100){_progress1.Visibility = Visibility.Collapsed;}}void _wc_OpenReadCompleted(object sender, OpenReadCompletedEventArgs e){System.Windows.Resources.StreamResourceInfo Info = new System.Windows.Resources.StreamResourceInfo(e.Result, "application/binary");AssemblyPart AP = new AssemblyPart();System.Reflection.Assembly Asm;System.Windows.Resources.StreamResourceInfo streamInfo = Application.GetResourceStream(Info, new Uri("SilverlightApplication2.dll", UriKind.Relative));Asm = AP.Load(streamInfo.Stream);var obj = (Asm.CreateInstance("SilverlightApplication2.MainPage") as FrameworkElement);obj.SetValue(Grid.ColumnProperty, 0);obj.SetValue(Grid.RowProperty, 0);LayoutRoot.Children.Add(obj);}}
}

XAML部分：

<UserControl x:Class="SilverlightApplication1.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:DesignWidth="640" d:DesignHeight="480"><Grid x:Name="LayoutRoot"><Grid.RowDefinitions><RowDefinition Height="*" /><RowDefinition Height="*" /></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinition Width="*"/><ColumnDefinition Width="*"/></Grid.ColumnDefinitions><TextBlock x:Name="_progress1" FontSize="30" Text="0%" Grid.Row="0" Grid.Column="0"/><TextBlock x:Name="_progress2" FontSize="30" Text="0%" Grid.Row="0" Grid.Column="1"/><TextBlock x:Name="_progress3" FontSize="30" Text="0%" Grid.Row="1" Grid.Column="0"/><TextBlock x:Name="_progress4" FontSize="30" Text="0%" Grid.Row="1" Grid.Column="1"/></Grid>
</UserControl>
