请教WPF代码增加控件的问题

Question

情况是这样的！我现在有一个WPF页面的模板！我把它的.xaml里面的内容取出来了。放到一个字符串里了！
想把一些增加控件的代码加到字符串里，然后我就可以重新生成一个WPF的页面，问题是怎么加进去呢？

给你个例子：PageTemplate.xaml
<Page x:Class="DynamicControl.PageTemplate"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="PageTemplate">
  <StackPanel x:Name="Container">
    
  </StackPanel>
</Page>Window1.xaml<Window x:Class="DynamicControl.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="Window1" Height="600" Width="800">
  <Grid>
    <Grid.RowDefinitions>
      <RowDefinition></RowDefinition>
      <RowDefinition Height="Auto"></RowDefinition>
    </Grid.RowDefinitions>
    <TextBox x:Name="TextBoxTemplate" Grid.Row="0"></TextBox>
    <StackPanel Orientation="Horizontal" Grid.Row="1" HorizontalAlignment="Center">
      <Button x:Name="AddButton" Content="Add Button" Click="AddButton_Click" Margin="10"></Button>
      <Button x:Name="AddTextBox" Content="Add TextBox" Click="AddTextBox_Click" Margin="10"></Button>
    </StackPanel>
  </Grid>
</Window>Window1.xaml.cs using System;

{
    /// <summary>
    /// Interaction logic for Window1.xaml

    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            DisplayObject(new PageTemplate());
        }        private void AddButton_Click(object sender, RoutedEventArgs e)
        {
            PageTemplate template = new PageTemplate();
            for (int i = 0; i < 5; ++i)
            {
                Button button = new Button();
                button.Name = string.Format("TestTextBox{0}", i);
                button.Content = string.Format("TestTextBox{0}", i);
                template.Container.Children.Add(button);
            }
            DisplayObject(template);
        }        private void AddTextBox_Click(object sender, RoutedEventArgs e)
        {
            PageTemplate template = new PageTemplate();
            for (int i = 0; i < 5; ++i)
            {
                TextBox textbox = new TextBox();
                textbox.Name = string.Format("TestTextBox{0}", i);
                textbox.Text = string.Format("TestTextBox{0}", i);
                template.Container.Children.Add(textbox);
            }
            DisplayObject(template);
        }        private void DisplayObject(object obj)
        {
            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            settings.IndentChars = new string(' ', 4);
            settings.NewLineOnAttributes = true;
            StringBuilder strBuild = new StringBuilder();
            XmlWriter xmlwrite = XmlWriter.Create(strBuild, settings);
            XamlWriter.Save(obj, xmlwrite);            TextBoxTemplate.Text = strBuild.ToString();
        }
    }
