C#学习小结

1. wpf窗体在屏幕中间显示

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

2.wpf窗体启动时，窗口最大化

 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

4.窗体之间数据的传递

窗体之间数据的传递是通过数据对象的属性进行传递的。

5.image.Source

private void button2_Click(object sender, RoutedEventArgs e)
        {
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Filter = "图片文件|*.PNG";
            if (ofd.ShowDialog() == true)
            {
                image1.Source = new BitmapImage(new Uri(ofd.FileName));


            }
        }
