WPF窗口不断更新GUI

我有一个WPF中的应用程序，它不断更改GUI屏幕中的值（更新！）。这会导致内存usuage上升。特别是所有堆中的＃字节。专用字节也增加。为了模拟一个更新GUI的类似场景，我使用下面的代码创建了一个简单的应用程序。WPF窗口不断更新GUI

namespace TextFieldUpdateTest 
{ 
    /// <summary> 
    /// Interaction logic for Window1.xaml 
    /// </summary> 
    public partial class Window1 : Window 
    { 
     Int32 Counter = 0; 
     Thread NewThread; 
     private delegate void ForLoop(); 
     public delegate void LoopHandler(object sender,EventArgs args); 
     public event LoopHandler LoopChange; 
     public Window1() 
     { 
      InitializeComponent(); 
      NewThread = new Thread(new ThreadStart(ForLoop1)); 
      LoopChange +=new LoopHandler(Window1_LoopChange); 
     } 

     private void button1_Click(object sender, RoutedEventArgs e) 
    { 
     if (!NewThread.IsAlive) 
     { 
      NewThread.Start(); 
     } 
    } 

    public void ForLoop1() 
    { 
     for (; ;) 
     { 
      LoopChange(0, EventArgs.Empty); 
      Thread.Sleep(10); 
     } 
    } 

    public void Window1_LoopChange(object sender,EventArgs args) 
    { 
     LoopChange -= this.Window1_LoopChange; 
     this.Dispatcher.Invoke(new ForLoop(ForLoop2)); 
     LoopChange +=new LoopHandler(Window1_LoopChange); 
    } 

    public void ForLoop2() 
    { 
     Counter++; 
     if (Counter % 2 == 0) 
     { 
      textBox1.Text = "11111"; 
      textBox2.Text = "22222"; 
      textBox3.Text = "33333"; 
      textBox4.Text = "44444"; 
      textBox5.Text = "55555"; 
      textBox6.Text = "66666"; 

     } 
     else 
     { 
      textBox1.Text = "00000"; 
      textBox2.Text = "77777"; 
      textBox3.Text = "88888"; 
      textBox4.Text = "99999"; 
      textBox5.Text = "10101"; 
      textBox6.Text = "45454"; 

     } 

    } 

    private void button2_Click(object sender, RoutedEventArgs e) 
    { 
     if (NewThread.IsAlive) NewThread.Abort(); 
    } 
} 
}

的XAML是

<Window x:Class="TextFieldUpdateTest.Window1" 
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
Title="Window1" Height="300" Width="427"> 
<Grid> 
    <Label Height="30" HorizontalAlignment="Left" Margin="42,41,0,0" Name="label1" VerticalAlignment="Top" Width="79">1</Label> 
    <Label Height="30" HorizontalAlignment="Left" Margin="42,72,0,0" Name="label2" VerticalAlignment="Top" Width="79">2</Label> 
    <Label HorizontalAlignment="Left" Margin="42,101,0,131" Name="label3" Width="79">3</Label> 
    <Label HorizontalAlignment="Left" Margin="42,131,0,101" Name="label4" Width="79">4</Label> 
    <Label Height="30" HorizontalAlignment="Left" Margin="42,0,0,71" Name="label5" VerticalAlignment="Bottom" Width="79">5</Label> 
    <Label Height="30" HorizontalAlignment="Left" Margin="42,0,0,40" Name="label6" VerticalAlignment="Bottom" Width="79">6</Label> 
    <TextBox Height="23" Margin="131,43,155,0" Name="textBox1" VerticalAlignment="Top" FontSize="16" /> 
    <TextBox Height="23" Margin="131,74,155,0" Name="textBox2" VerticalAlignment="Top" FontSize="16" /> 
    <TextBox Height="23" Margin="131,103,155,0" Name="textBox3" VerticalAlignment="Top" FontSize="16"/> 
    <TextBox Height="23" Margin="131,0,155,106" Name="textBox4" VerticalAlignment="Bottom" FontSize="16" /> 
    <TextBox Height="23" Margin="131,0,155,78" Name="textBox5" VerticalAlignment="Bottom" FontSize="16" /> 
    <TextBox Height="23" Margin="131,0,155,47" Name="textBox6" VerticalAlignment="Bottom" FontSize="16" /> 
    <Button Height="23" HorizontalAlignment="Right" Margin="0,41,22,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click">Button1</Button> 
    <Button Height="23" HorizontalAlignment="Right" Margin="0,101,22,0" Name="button2" VerticalAlignment="Top" Width="75" Click="button2_Click">Button2</Button> 
</Grid>

现在，我无法运行该代码（编辑：代码变化，从而它编译并运行正常，但内存的问题仍然存在，我减少了睡眠时间，使其更加明显）。可能是什么原因。

谢谢。

存储信息的数据类（必须实现INotifyPropertyChanged以更新UI更改）。这解决了永久增加的记忆问题。
