WPF 通过辅助方法在 csharp 代码写出 XAML 界面效果

            var border = new Border()
            {
                Background = Brushes.Gray,
                Width = 100,
                Height = 100,
                Child = new Grid
                {
                    Children =
                    {
                        new StackPanel()
                        {
                            Orientation = Orientation.Horizontal,
                            VerticalAlignment = VerticalAlignment.Bottom,
                            Margin = new Thickness(10, 10, 10, 10),
                            Children =
                            {
                                new Button
                                {

                                }.Do(b => { b.Click += Foo_Click; })
                            }
                        }
                    }
                }
            };

    public static class UIInitExtensions
    {
        public static Button Do(this Button button, Action<Button> action)
        {
            action(button);
            return button;
        }
    }
