WPF 登录界面
没用背景图，自己实现一些背景效果
<Window Loaded="Window_Loaded" > <Grid> <Ellipse Grid.Row="1" x:Name="blueQ" Stroke="Black" Fill="#FF1C84EE"/> </Grid> </Window>
private void Window_Loaded(object sender, RoutedEventArgs e) { blueQ.Width = this.ActualHeight * 2; blueQ.Height = this.ActualHeight * 2; blueQ.Margin = new Thickness(-this.ActualHeight, -this.ActualHeight, 0, 0); }
