如何實現一個窗口的風格（style），讓所有的窗口都繼承這樣同樣的風格，包括標題欄，放大、縮小和關閉按鈕。

?那么，我們可不可以就建立一個Base窗口，然后將這個窗口的風格給設計好之后，所有的窗口都繼承自他呢？

答案是否定的，我們一定要知道，窗口是一個類，它可以繼承，但是風格（XAML)文件是繼承不了的。

所以我們能夠做到的是：

1、窗口類繼承，BaseWindow封裝窗口最大化按鈕，最小化按鈕的點擊等事件。

2、風格（Style）就利用屬性來設置，把window看成一個控件，利用Style=“BaseWindowStyle”就可以了。

以下是詳細的步驟：

1、新建一個BaseWindowStyle的模板文件。點擊項目名稱，右鍵“添加”->”資源字典”->輸入名稱為“BaseWindowStyle.xaml”，然后將以下的末班文件拷貝進去：

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><ControlTemplate x:Key="WindowTemplateKey"TargetType="{x:Type Window}"><Border Background="{TemplateBinding Background}"BorderBrush="{TemplateBinding BorderBrush}"BorderThickness="{TemplateBinding BorderThickness}"><Grid><AdornerDecorator><ContentPresenter /></AdornerDecorator><ResizeGrip Visibility="Collapsed"IsTabStop="false"HorizontalAlignment="Right"x:Name="WindowResizeGrip"VerticalAlignment="Bottom" /></Grid></Border><ControlTemplate.Triggers><MultiTrigger><MultiTrigger.Conditions><Condition Property="ResizeMode"Value="CanResizeWithGrip" /><Condition Property="WindowState"Value="Normal" /></MultiTrigger.Conditions><Setter Property="Visibility"TargetName="WindowResizeGrip"Value="Visible" /></MultiTrigger></ControlTemplate.Triggers></ControlTemplate><ControlTemplate x:Key="BaseWindowControlTemplate" TargetType="{x:Type Window}"><DockPanel LastChildFill="True"><!--外邊框--><Border Width="Auto"Height="Auto"DockPanel.Dock="Top"Background="#FF7097D0"CornerRadius="0,0,0,0"x:Name="borderTitle"><Grid><Grid.ColumnDefinitions><ColumnDefinition

Foreground="White" Text="{TemplateBinding Title}"/><StackPanel Grid.Column="1" HorizontalAlignment="Right" Orientation="Horizontal"><!--最小化按鈕--><Button x:Name="btnMin" Content="M" Margin="2,2,2,2"

BorderBrush}"BorderThickness="{TemplateBinding BorderThickness}"Width="Auto"Height="Auto"DockPanel.Dock="Top"CornerRadius="0,0,4,4"><AdornerDecorator><ContentPresenter /></AdornerDecorator></Border></DockPanel></ControlTemplate><Style x:Key="BaseWindowStyle"TargetType="{x:Type Window}"><Setter Property="Foreground"Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" /><Setter Property="Background"Value="{DynamicResource {x:Static SystemColors.WindowBrushKey}}" /><Setter Property="Template" Value="{StaticResource BaseWindowControlTemplate}"/><Setter Property="AllowsTransparency"Value="True" /><Setter Property="WindowStyle"Value="None" /><Setter Property="BorderBrush"Value="#FF7097D0" /><Setter Property="BorderThickness"Value="4,4,4,4" /><Style.Triggers><Trigger Property="ResizeMode"Value="CanResizeWithGrip"><Setter Property="Template"Value="{StaticResource WindowTemplateKey}" /></Trigger></Style.Triggers></Style><!--最小化按鈕--><Style x:Key="MinButtonStyle" TargetType="{x:Type Button}"><Setter Property="Foreground" Value="Black"/><!--修改模板屬性--><Setter

/></Path.Data></Path></Border><ControlTemplate.Triggers><Trigger Property="IsMouseOver" Value="True"><Setter Property="Background" TargetName="back" Value="#FFD4BD9B"/></Trigger><Trigger

Value="#FFCDA05F"/></Trigger></ControlTemplate.Triggers></ControlTemplate></Setter.Value></Setter></Style></ResourceDictionary>

2、引用該模板文件。資源文件建立后，我們需要在程序中引用這個文件，打開APP.XAML,將引用的BaseWindowStyle添加進去：

<Applicationxmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="MyFirst.App"StartupUri="MainWindow.xaml"><Application.Resources><ResourceDictionary Source="BaseWindowStyle.xaml"></ResourceDictionary></Application.Resources> </Application>

3、建立BaseWindow類，實現窗口點擊，拖動等事件。在工程上點擊右鍵“添加”->“類”->輸入”BaseWindow.cs“

該類繼承自Window,然后要載入模板文件，在模板文件中獲取最小化、最大化等按鈕，然后將這些按鈕的點擊事件和窗口綁定起來，實現窗口的響應：

using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Input;namespace MyFirst {public class BaseWindow : Window{public BaseWindow(){InitializeStyle();this.Loaded += delegate{InitializeEvent();};}private void InitializeEvent(){ControlTemplate baseWindowTemplate = (ControlTemplate)App.Current.Resources["BaseWindowControlTemplate"];Button minBtn = (Button)baseWindowTemplate.FindName("btnMin", this);minBtn.Click += delegate{this.WindowState = WindowState.Minimized;};Button maxBtn = (Button)baseWindowTemplate.FindName("btnMax", this);maxBtn.Click += delegate{this.WindowState = (this.WindowState == WindowState.Normal ? WindowState.Maximized : WindowState.Normal);};Button closeBtn = (Button)baseWindowTemplate.FindName("btnClose", this);closeBtn.Click += delegate{this.Close();};Border borderTitle = (Border)baseWindowTemplate.FindName("borderTitle", this);borderTitle.MouseMove += delegate(object sender, MouseEventArgs e){if (e.LeftButton == MouseButtonState.Pressed){this.DragMove();}};borderTitle.MouseLeftButtonDown += delegate(object sender, MouseButtonEventArgs e){if (e.ClickCount >= 2){maxBtn.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));}};}private void InitializeStyle(){this.Style = (Style)App.Current.Resources["BaseWindowStyle"];}} }

?

4，其它窗口類繼承自BaseWindow:

public partial class?MainWindow : BaseWindow

5，其它窗口的風格指向BaseWindowStyle。

這里要注意一點Winodow的風格可不是直接 Style=”BaseWindowStyle” 那么簡單，可以看看MainWindow.xaml的代碼：

<local:BaseWindow x:Class="MyFirst.Login"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:src="clr-namespace:MyFirst"Title="MainWindow" Height="300" Width="300"></local:BaseWindow>

?

經過這么多步，我們終于實現了凡是繼承自BaseWindow的窗口，都有統一的風格了！

當然，如上的窗口還不是那么漂亮完美，但是相信你有辦法把它做的美美的！
