一．前言
申明：WPF自定义控件与样式是一个系列文章，前后是有些关联的，但大多是按照由简到繁的顺序逐步发布的等。
本文主要内容：
自定义Window窗体样式；基于自定义窗体实现自定义MessageBox消息提示框；
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：
第一步：干掉默认样式：WindowStyle = WindowStyle.None；第二步：设置窗体透明：AllowsTransparency = true；第三步：设置自己的窗体样式；
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：
窗体Icon、标题栏（可以通过样式实现）；窗体的基本按钮：最小化、最大化、关闭按钮；窗体的鼠标拖动；好像Win8、Win10的功能吧，窗体拖动到桌面边缘自动最大化、还原；鼠标调整窗口大小；双击标题栏最大化、还原；
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：
/// <summary>/// WindowBase.xaml 的交互逻辑/// </summary>public class WindowBase : Window{#region 默认Header：窗体字体图标FIconpublic static readonly DependencyProperty FIconProperty =DependencyProperty.Register("FIcon", typeof(string), typeof(WindowBase), new PropertyMetadata("\ue62e"));/// <summary>/// 按钮字体图标编码/// </summary>public string FIcon{get { return (string)GetValue(FIconProperty); }set { SetValue(FIconProperty, value); }}#endregion#region 默认Header：窗体字体图标大小public static readonly DependencyProperty FIconSizeProperty =DependencyProperty.Register("FIconSize", typeof(double), typeof(WindowBase), new PropertyMetadata(20D));/// <summary>/// 按钮字体图标大小/// </summary>public double FIconSize{get { return (double)GetValue(FIconSizeProperty); }set { SetValue(FIconSizeProperty, value); }}#endregion#region CaptionHeight 标题栏高度public static readonly DependencyProperty CaptionHeightProperty =DependencyProperty.Register("CaptionHeight", typeof(double), typeof(WindowBase), new PropertyMetadata(26D));/// <summary>/// 标题高度/// </summary>public double CaptionHeight{get { return (double)GetValue(CaptionHeightProperty); }set{SetValue(CaptionHeightProperty, value);//this._WC.CaptionHeight = value; }}#endregion#region CaptionBackground 标题栏背景色public static readonly DependencyProperty CaptionBackgroundProperty = DependencyProperty.Register("CaptionBackground", 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public static readonly DependencyProperty CaptionForegroundProperty = DependencyProperty.Register("CaptionForeground", 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public static readonly DependencyProperty HeaderProperty = DependencyProperty.Register("Header", 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public static readonly DependencyProperty MaxboxEnableProperty = DependencyProperty.Register("MaxboxEnable", 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public static readonly DependencyProperty MinboxEnableProperty = DependencyProperty.Register("MinboxEnable", typeof(bool), typeof(WindowBase), new PropertyMetadata(true));public bool MinboxEnable{get { return (bool)GetValue(MinboxEnableProperty); }set { SetValue(MinboxEnableProperty, value); }}#endregionpublic WindowBase(){this.WindowStyle = WindowStyle.None;this.AllowsTransparency = true;this.WindowStartupLocation = WindowStartupLocation.CenterScreen;this.Style = this.FindResource("DefaultWindowStyle") as Style;this.Icon = Images.CreateImageSourceFromImage(Properties.Resources.logo);//12=6+6//Margin=6,Border.Effect.BlueRadius=6this.MaxHeight = SystemParameters.WorkArea.Height + 12 + 2;//bind commandthis.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;}protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e){base.OnMouseLeftButtonDown(e);if (e.ButtonState == MouseButtonState.Pressed){this.DragMove();}}}
绑定命令的扩展方法：
/// <summary>/// 绑定命令和命令事件到宿主UI/// </summary>public static void BindCommand(this UIElement @ui, ICommand com, Action<object, ExecutedRoutedEventArgs> call){var bind = new CommandBinding(com);bind.Executed += new ExecutedRoutedEventHandler(call);@mandBindings.Add(bind);}
WindowBase的样式有两个，一个是基础样式BaseWindowStyle，可以自定义头部标题栏，提供更多定制需求。另一个样式DefaultWindowStyle为默认窗体样式，用于大多数不要特别定制的窗体需求。BaseWindowStyle样式代码：

三．实现自定义MessageBox消息提示框
基于第二节自定义的窗体WindowBase，实现自定义的MessageBox就简单了，效果图：
仔细观察，不难发现上面的窗体大小是根据内容的多少自适应的。窗体自适应内容的的关键设置就是SizeToContent="WidthAndHeight"，但为了达到更好的效果控制，还需要控制内容的大小范围，范围可以自己调整，看了样式代码你就了解了：
<local:WindowBase x:Class="System.Windows.MessageBoxX"xmlns="/winfx//xaml/presentation"xmlns:x="/winfx//xaml"xmlns:shell="/winfx//xaml/presentation/shell"xmlns:local="clr-namespace:XLY.Framework.Controls" MaxboxEnable="False" MinboxEnable="False" ResizeMode="NoResize" FIcon="" x:Name="mb" Title="MessageBox" ShowInTaskbar="False" SizeToContent="WidthAndHeight" Style="{StaticResource DefaultWindowStyle}" CaptionHeight="24"> <local:WindowBase.InputBindings><KeyBinding Key="Escape" Command="{x:Static shell:SystemCommands.CloseWindowCommand}"/></local:WindowBase.InputBindings><Grid><Grid Margin="5,8,5,5"><Grid.RowDefinitions><RowDefinition Height="*"/><RowDefinition Height="60"/></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinition Width="100"/><ColumnDefinition Width="*"/></Grid.ColumnDefinitions><TextBlock x:Name="ficon" HorizontalAlignment="Right" FontSize="80" Text="" Foreground="{Binding Foreground,ElementName=mb}" Style="{StaticResource FIcon}" Margin="5"/><TextBlock x:Name="txtMessage" Grid.Column="1" VerticalAlignment="Center" HorizontalAlignment="Left" Foreground="{Binding Foreground,ElementName=mb}" FontSize="{Binding FontSize,ElementName=mb}" TextWrapping="Wrap" Margin="5,20,10,20" MinWidth="260" MaxWidth="420">新建一个WPF程序在Windows8下面就会出现左边的窗口边框，颜色取决于Windows主题我想在想创建一个右边那样的窗口，要么是窄边，要么没有边</TextBlock><StackPanel Orientation="Horizontal" VerticalAlignment="Top" Margin="1" Grid.Column="0" Grid.Row="1" Grid.ColumnSpan="2" HorizontalAlignment="Center"><local:FButton x:Name="btnOK" FIcon="" Width="85" Height="30" CornerRadius="0" Margin="5,5,20,5" Click="btnOK_Click">确定</local:FButton><local:FButton x:Name="btnCancel" FIcon="" Width="85" Height="30" CornerRadius="0"Margin="20,5,10,5" Click="btnCancel_Click">取消</local:FButton></StackPanel></Grid></Grid></local:WindowBase>
上面不同消息类型的颜色资源：
<!--MessageBoxX--><SolidColorBrush x:Key="InfoForeground" Color="White"></SolidColorBrush><SolidColorBrush x:Key="QuestionForeground" Color="#74B80C"></SolidColorBrush><SolidColorBrush x:Key="WarningForeground" Color="DarkOrange"></SolidColorBrush><SolidColorBrush x:Key="ErrorForeground" Color="#E74E4E"></SolidColorBrush>
