C#学习总结

1. wpf窗体在屏幕中间显示

 public MainWindow()        {            InitializeComponent();            this.WindowStartupLocation = WindowStartupLocation.CenterScreen;        }

 private void calculator_Loaded(object sender, RoutedEventArgs e)        {            //this.WindowState = System.Windows.WindowState.Normal;            //this.WindowStyle = System.Windows.WindowStyle.None;            //this.ResizeMode = System.Windows.ResizeMode.NoResize;            //this.Topmost = true;            this.Left = 0.0;            this.Top = 0.0;            this.Width = System.Windows.SystemParameters.PrimaryScreenWidth;            this.Height = System.Windows.SystemParameters.PrimaryScreenHeight;        }

3.wpf窗体设置背景图片

<Window.Background>        <VisualBrush TileMode="Tile" Viewport="0,0,0.5,0.5" Stretch="None" ViewboxUnits="RelativeToBoundingBox" AlignmentY="Center">            <VisualBrush.Visual>                <Image Source="background.jpg" Width="308" Height="399" Stretch="Fill" StretchDirection="Both"></Image>            </VisualBrush.Visual>        </VisualBrush>    </Window.Background>
