運行以下代碼將全屏打開應用程式。單擊寬度按鈕應將應用程式寬度更改為 500，但不會更改為更小。還有什么需要補充的嗎？
主視窗.xaml

主視窗.xaml.cs
namespace WpfApp1
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void Button_Click(object sender, RoutedEventArgs e)
{
this.Width = System.Convert.ToDouble(xwidth.Text);
}
private void Window_SizeChanged(object sender, SizeChangedEventArgs e)
{
Console.WriteLine("changed " System.Convert.ToString(this.Width));
}
}
}
uj5u.com熱心網友回復：
WindowState 已最大化，將其更改為正常
private void Button_Click(object sender, RoutedEventArgs e){
WindowState = WindowState.Normal;
Width = Convert.ToDouble(xwidth.Text);
}
