二．自定义Window窗体样式

　　自定义的Window窗体效果：

　　因为WPF默认的窗体比较简陋，大都需要自己实现Window窗体样式效果，基本思路很简单：

　　这样从外观样式上可以满足，但做为窗体该具备的基本功能还没有，需要另外来实现了：

　　上面的功能在本文中，一部分是自定义实现的，还有一部分是用了一个开源库（Microsoft.Windows.Shell）用于实现窗体大小、拖放等窗体基本功能，Microsoft.Windows.Shell文件下载：点我下载。

　　进入正题，自定义窗体WindowBase的后台C#代码：  

WindowBase.xaml 的交互逻辑 WindowBase : Window { #region 默认Header：窗体字体图标FIcon DependencyProperty FIconProperty = DependencyProperty.Register(, )); 按钮字体图标编码 FIcon { get { return (string)GetValue(FIconProperty); } set { SetValue(FIconProperty, value); } } #endregion #region 默认Header：窗体字体图标大小 DependencyProperty FIconSizeProperty = DependencyProperty.Register(, typeof(double), typeof(WindowBase), new PropertyMetadata(20D)); 按钮字体图标大小 FIconSize { get { return (double)GetValue(FIconSizeProperty); } set { SetValue(FIconSizeProperty, value); } } #endregion #region CaptionHeight 标题栏高度 DependencyProperty CaptionHeightProperty = DependencyProperty.Register(, typeof(double), typeof(WindowBase), new PropertyMetadata(26D)); 标题高度 CaptionHeight { get { return (double)GetValue(CaptionHeightProperty); } set { SetValue(CaptionHeightProperty, value); //this._WC.CaptionHeight = value; } } #endregion #region CaptionBackground 标题栏背景色 DependencyProperty CaptionBackgroundProperty = DependencyProperty.Register( , typeof(Brush), typeof(WindowBase), new PropertyMetadata(null)); public Brush CaptionBackground { get { return (Brush)GetValue(CaptionBackgroundProperty); } set { SetValue(CaptionBackgroundProperty, value); } } #endregion #region CaptionForeground 标题栏前景景色 DependencyProperty CaptionForegroundProperty = DependencyProperty.Register( , typeof(Brush), typeof(WindowBase), new PropertyMetadata(null)); public Brush CaptionForeground { get { return (Brush)GetValue(CaptionForegroundProperty); } set { SetValue(CaptionForegroundProperty, value); } } #endregion #region Header 标题栏内容模板，以提高默认模板，可自定义 DependencyProperty HeaderProperty = DependencyProperty.Register( , typeof(ControlTemplate), typeof(WindowBase), new PropertyMetadata(null)); public ControlTemplate Header { get { return (ControlTemplate)GetValue(HeaderProperty); } set { SetValue(HeaderProperty, value); } } #endregion #region MaxboxEnable 是否显示最大化按钮 DependencyProperty MaxboxEnableProperty = DependencyProperty.Register( , typeof(bool), typeof(WindowBase), new PropertyMetadata(true)); public bool MaxboxEnable { get { return (bool)GetValue(MaxboxEnableProperty); } set { SetValue(MaxboxEnableProperty, value); } } #endregion #region MinboxEnable 是否显示最小化按钮 DependencyProperty MinboxEnableProperty = DependencyProperty.Register( , typeof(bool), typeof(WindowBase), new PropertyMetadata(true)); public bool MinboxEnable { get { return (bool)GetValue(MinboxEnableProperty); } set { SetValue(MinboxEnableProperty, value); } } #endregion public WindowBase() { this.WindowStyle = WindowStyle.None; this.AllowsTransparency = true; this.WindowStartupLocation = WindowStartupLocation.CenterScreen; ) as Style; this.Icon = Images.CreateImageSourceFromImage(Properties.Resources.logo); .MaxHeight = SystemParameters.WorkArea.Height + 12 + 2; .BindCommand(SystemCommands.CloseWindowCommand, this.CloseCommand_Execute); this.BindCommand(ApplicationCommands.Close, this.CloseCommand_Execute); this.BindCommand(SystemCommands.MaximizeWindowCommand, this.MaxCommand_Execute); this.BindCommand(SystemCommands.MinimizeWindowCommand, this.MinCommand_Execute); } private void CloseCommand_Execute(object sender, ExecutedRoutedEventArgs e) { SystemCommands.CloseWindow(this); } private void MaxCommand_Execute(object sender, ExecutedRoutedEventArgs e) { this.WindowState = this.WindowState == WindowState.Maximized ? WindowState.Normal : WindowState.Maximized; e.Handled = true; } private void MinCommand_Execute(object sender, ExecutedRoutedEventArgs e) { this.WindowState = WindowState.Minimized; e.Handled = true; } OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); if (e.ButtonState == MouseButtonState.Pressed) { this.DragMove(); } } }
