使用代码隐藏在wpf中创建圆角形状

下面是一个简单的示例,介绍如何创建 Grid

XAML:

<Grid x:Name="root"></Grid>

代码隐藏:

Grid g = new Grid();
ColumnDefinition cd1 = new ColumnDefinition();
ColumnDefinition cd2 = new ColumnDefinition();
ColumnDefinition cd3 = new ColumnDefinition();
cd1.Width = new GridLength(15, GridUnitType.Pixel);
cd2.Width = new GridLength(200, GridUnitType.Pixel);
cd3.Width = new GridLength(15, GridUnitType.Pixel);
g.ColumnDefinitions.Add(cd1);
g.ColumnDefinitions.Add(cd2);
g.ColumnDefinitions.Add(cd3);

RowDefinition rd1 = new RowDefinition();
RowDefinition rd2 = new RowDefinition();
RowDefinition rd3 = new RowDefinition();
rd1.Height = new GridLength(15, GridUnitType.Pixel);
rd2.Height = new GridLength(100, GridUnitType.Pixel);
rd3.Height = new GridLength(15, GridUnitType.Pixel);
g.RowDefinitions.Add(rd1);
g.RowDefinitions.Add(rd2);
g.RowDefinitions.Add(rd3);

Border border = new Border();
border.BorderThickness = new Thickness(2, 2, 2, 2);
border.BorderBrush = Brushes.Red;
border.CornerRadius = new CornerRadius(15, 15, 15, 15);
Grid.SetColumn(border, 0);
Grid.SetRow(border, 0);
Grid.SetColumnSpan(border, 3);
Grid.SetRowSpan(border, 3);

Grid contentGrid = new Grid();
contentGrid.Background = Brushes.Yellow;
Grid.SetColumn(contentGrid, 1);
Grid.SetRow(contentGrid, 1);

g.Children.Add(border);
g.Children.Add(contentGrid);
root.Children.Add(g);
