需求：封装按钮，按钮上面只显示文字。在鼠标移上去、鼠标点击按钮、以及将按钮设为不可用时按钮的背景色和前景色需要发生变化

实现：继承Button类，封装如下6个属性：

#region 依赖属性/// 
/// 当鼠标移到按钮上时，按钮的前景色（这是依赖属性）/// 
public static readonly DependencyProperty MouserOverForegroundProperty =    DependencyProperty.Register ( "MouserOverForeground", typeof ( Brush ), typeof ( TextButton ), new PropertyMetadata ( Brushes.Black ) );/// 
/// 鼠标移到按钮上时，按钮的背景色（这是依赖属性）/// 
public static readonly DependencyProperty MouseOverBackgroundProperty =    DependencyProperty.Register ( "MouseOverBackground", typeof ( Brush ), typeof ( TextButton ), new PropertyMetadata ( Brushes.White ) );/// 
/// 当鼠标按下时，按钮的前景色（这是依赖属性）/// 
public static readonly DependencyProperty MousedownForegroundProperty =    DependencyProperty.Register ( "MousedownForeground", typeof ( Brush ), typeof ( TextButton ), new PropertyMetadata ( Brushes.Black ) );/// 
/// 当鼠标按下时，按钮的背景色（这是依赖属性）/// 
public static readonly DependencyProperty MousedownBackgroundProperty =    DependencyProperty.Register ( "MousedownBackground", typeof ( Brush ), typeof ( TextButton ), new PropertyMetadata ( Brushes.White ) );/// 
/// 当按钮不可用时，按钮的前景色（这是依赖属性）/// 
public static readonly DependencyProperty DisabledForegroundProperty =    DependencyProperty.Register ( " DisabledForeground", typeof ( Brush ), typeof ( TextButton ), new PropertyMetadata ( Brushes.Black ) );/// 
/// 当按钮不可用时，按钮的背景色（这是依赖属性）/// 
public static readonly DependencyProperty DisabledBackgroundProperty =    DependencyProperty.Register ( "DisabledBackground", typeof ( Brush ), typeof ( TextButton ), new PropertyMetadata ( Brushes.White ) );#endregion

然后更改按钮的样式，样式封装在资源字典中：

然后在TextButton的构造函数中设置按钮的样式：

#region 构造函数public TextButton() : base(){    //获取资源文件信息    ResourceDictionary rd = new ResourceDictionary();    rd.Source = new Uri ( "/Zmy.Wpf.Controls;component/Style.xaml", UriKind.Relative );    this.Resources.MergedDictionaries.Add ( rd );    //设置样式    this.Style = this.FindResource ( "TextButtonStyle" ) as Style;}#endregion

这样整个文字按钮就封装好了，调用起来非常简单：
