XAML代码实现：
<Window x:Class="WPFLayoutDemo.ViewBoxDemo"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="ViewBoxDemo" Height="342" Width="535">
<Viewbox Stretch="Uniform">
<Button Content="Hello,Knights Warrior" />
</Viewbox></Window>
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="ViewBoxDemo" Height="342" Width="535">
<Viewbox Stretch="Uniform">
<Button Content="Hello,Knights Warrior" />
</Viewbox></Window>
C#代码实现：
namespace WPFLayoutDemo
{
public partial class ViewBoxDEMOBehind : Window
{
public ViewBoxDEMOBehind()
{
this.InitializeComponent();
Viewbox vb = new Viewbox();
vb.Stretch = Stretch.Uniform ;
//把vb添加为窗体的子控件
this.Content = vb;
//Button1
Button b1 = new Button();
b1.Content = "Hello,Knights Warrior";
vb.Child=b1;
}
}
}
{
public partial class ViewBoxDEMOBehind : Window
{
public ViewBoxDEMOBehind()
{
this.InitializeComponent();
Viewbox vb = new Viewbox();
vb.Stretch = Stretch.Uniform ;
//把vb添加为窗体的子控件
this.Content = vb;
//Button1
Button b1 = new Button();
b1.Content = "Hello,Knights Warrior";
vb.Child=b1;
}
}
}
十一. Border
Border 是一个装饰的控件，此控件绘制边框及背景，在 Border 中只能有一个子控件(这个子控件又可以包含多个子控件)。Border 的几个重要属性：Background:用用一个 Brush 对象来绘制背景 ;BorderBrush:用一个Brush 对象来绘制边框 ;BorderThickness:此属性设置 Border 边框的大小;CornerRadius:此属性设置 Border 的每一个角圆的半径;Padding:此r属性设置 Border 里的内容与边框的之间的间隔。
要实现的效果如下图(用XAML和C#实现同一效果)：
