本文介绍了在WPF应用程序中实现主题切换的两种方法，一种是在XAML中直接设置主题，另一种是在运行时通过用户交互来改变主题。通过具体示例展示了如何在界面上设置不同的主题风格。

wpf中更换主题包含多种方式，这里介绍两种常用方式，方式一：在xaml中更换主题即使用默认主题，方式二：在软件页面中更换主题。

方式一实现方法：

在窗体属性中添加主题属性即可：dx:ThemeManager.ThemeName="Office2007Blue"

方式二实现方式：

方式二实现想比较方式一复杂一点，这里我列举一种相对简单的方法：

第一步：添加主题图片，可以从源码中查找。

第二步：在RibbonGalleryBarItem中添加主题列表（也可以使用其他控件），xaml代码如下：

<dxr:RibbonGalleryBarItem x:Name="gTheme"  >
                    <dxr:RibbonGalleryBarItem.Gallery>
                        <dxb:Gallery MinColCount="2" ColCount="10" RowCount="2" 
							ItemCheckMode="Single" AllowHoverAnimation="True" AllowHoverImages="True" 
							FilterCaption="Themes" IsItemCaptionVisible="False" ItemCaptionHorizontalAlignment="Center" 
							HoverGlyphSize="48,48" ItemClick="Gallery_ItemClick" ItemGlyphSize="24,24" ItemGlyphStretch="Uniform">
                            <dxb:GalleryItemGroup Caption="Standard" >
                                <dxb:GalleryItem Caption="DXStyle" Glyph="Images/ThemeIcons/DXStyle.png" />
                                <dxb:GalleryItem Caption="VS2010" Glyph="Images/ThemeIcons/VS2010.png"/>
                                <dxb:GalleryItem Caption="MetropolisDark" Glyph="Images/ThemeIcons/MetropolisDark.png"/>
                                <dxb:GalleryItem Caption="MetropolisLight" Glyph="Images/ThemeIcons/MetropolisLight.png"/>
                                <dxb:GalleryItem Caption="Seven" Glyph="Images/ThemeIcons/Seven_48x48.png"/>
                                <dxb:GalleryItem Caption="Light Gray" Glyph="Images/ThemeIcons/LightGray_48x48.png" />
                                <dxb:GalleryItem Caption="Deep Blue" Glyph="Images/ThemeIcons/DeepBlue_48x48.png"/>
                            </dxb:GalleryItemGroup>
                            <dxb:GalleryItemGroup Caption="Office2007">
                                <dxb:GalleryItem Caption="Office 2007 Black" Glyph="Images/ThemeIcons/Office2007Black_48x48.png"/>
                                <dxb:GalleryItem Caption="Office 2007 Blue" Glyph="Images/ThemeIcons/Office2007Blue_48x48.png"/>
                                <dxb:GalleryItem Caption="Office 2007 Silver" Glyph="Images/ThemeIcons/Office2007Silver_48x48.png"/>
                            </dxb:GalleryItemGroup>
                            <dxb:GalleryItemGroup Caption="Office2010">
                                <dxb:GalleryItem Caption="Office 2010 Black" Glyph="Images/ThemeIcons/Office2010Black_48x48.png"/>
                                <dxb:GalleryItem Caption="Office 2010 Blue" Glyph="Images/ThemeIcons/Office2010Blue_48x48.png"/>
                                <dxb:GalleryItem Caption="Office 2010 Silver" Glyph="Images/ThemeIcons/Office2010Silver_48x48.png"/>
                            </dxb:GalleryItemGroup>
                            <dxb:GalleryItemGroup Caption="Office2013">
                                <dxb:GalleryItem Caption="Office 2013" Glyph="Images/ThemeIcons/Office2013_48x48.png"/>
                                <dxb:GalleryItem Caption="Office 2013 DarkGray" Glyph="Images/ThemeIcons/Office2013DarkGray_48x48.png"/>
                                <dxb:GalleryItem Caption="Office 2013 LightGray" Glyph="Images/ThemeIcons/Office2013LightGray_48x48.png"/>
                            </dxb:GalleryItemGroup>
                        </dxb:Gallery>
                    </dxr:RibbonGalleryBarItem.Gallery>
                </dxr:RibbonGalleryBarItem>

关联子项，代码如下：

<dxr:RibbonDefaultPageCategory>
                            <dxr:RibbonPageGroup Caption="主题">
                                <dxr:RibbonGalleryBarItemLink BarItemName="gTheme"/>
                            </dxr:RibbonPageGroup>
                        </dxr:RibbonPage>
                    </dxr:RibbonDefaultPageCategory>

第三步，在Gallery_ItemClick事件中添加切换主题的代码如下所示：

        private void Gallery_ItemClick(object sender, DevExpress.Xpf.Bars.GalleryItemEventArgs e)
        {
            string themeName = (string)e.Item.Caption;
            themeName = themeName.Replace(" ", string.Empty);
            DevExpress.Xpf.Core.ThemeManager.SetThemeName(this, themeName);
        }

最后，贴一张效果图：
