我在 WPF 中有一个应用程序，它不断更改 GUI 屏幕中的值（更新！）。这会导致内存使用量上升。特别是所有堆中的#of Bytes。私有字节也会增加。为了模拟始终更新 GUI 的类似场景，我使用以下代码创建了一个简单的应用程序。
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();
}
}
}
XAML 是

现在，我无法运行此代码（编辑：代码已更改，使其编译和运行正常，但内存问题仍然存在，我减少了睡眠时间，使其更明显）。可能是什么原因。
谢谢。
