【问题描述】：

几天前我开始使用 mahapps（仍在学习），我尝试在标题栏中添加一个图标，我所做的一切都与他们网站上的示例相同，但它不会出现。这就是我正在尝试的：

<Controls:MetroWindow.RightWindowCommands>
    <Controls:WindowCommands>
    <StackPanel Orientation="Horizontal">
        <Rectangle Width="20"
               Height="20"
               Fill="{Binding RelativeSource={RelativeSource AncestorType=Button}, Path=Foreground}">
            <Rectangle.OpacityMask>
                <VisualBrush Stretch="Fill" Visual="{StaticResource appbar_cog}" />
            </Rectangle.OpacityMask>
        </Rectangle>
        <Button Margin="4 0 0 0" Content="settings" Click="Button_Click"/>
    </StackPanel>
    </Controls:WindowCommands>
</Controls:MetroWindow.RightWindowCommands>`

还有我的 app.xaml：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.AnimatedTabControl.xaml" />
            <ResourceDictionary Source="/Resources/Icons.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

如何让图标出现？这是我希望它看起来像的示例：

【解决方案1】：

试试这个：

MainWindow.xaml：

<Controls:MetroWindow x:Class="MahApps.Metro.Application31.MainWindow"
                  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                  xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
                  Icon="mahapps.metro.logo2.png"
                  BorderBrush="{StaticResource AccentColorBrush}"
                  BorderThickness="2"
                  Title="MainWindow"
                  Height="350"
                  Width="350">

<Controls:MetroWindow.RightWindowCommands>
    <Controls:WindowCommands>
        <Button>
            <StackPanel Orientation="Horizontal">
                <Rectangle Width="20"
                           Height="20"
                           Fill="{Binding RelativeSource={RelativeSource AncestorType=Button}, Path=Foreground}">
                    <Rectangle.OpacityMask>
                        <VisualBrush Stretch="Fill" Visual="{StaticResource appbar_cog}" />
                    </Rectangle.OpacityMask>
                </Rectangle>
                <TextBlock Margin="5,0,0,0">Settings</TextBlock>
            </StackPanel>
        </Button>
    </Controls:WindowCommands>
</Controls:MetroWindow.RightWindowCommands>

<Grid>
    <Rectangle Fill="{StaticResource AccentColorBrush}">
        <Rectangle.OpacityMask>
            <VisualBrush Stretch="Fill"
                         Visual="{StaticResource appbar_cog}" />
        </Rectangle.OpacityMask>
    </Rectangle>
</Grid>

App.xaml：

<Application x:Class="MahApps.Metro.Application31.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         StartupUri="MainWindow.xaml">
<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Controls.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Fonts.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Colors.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Blue.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseLight.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro.Resources;component/Icons.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

注意事项：要让一切正常工作，您需要：

1) 将mahapps.metro.logo2.png 显式添加到您的项目中； 2) 显式添加对MahApps.Metro.Resources的项目引用

谢谢！它起作用了，奇怪的是如何将它全部放在一个按钮中解决它

【解决方案2】：

在您的代码中使用Icon 和ShowIconOnTitleBar 和ShowTitleBar，如下所示：

<Controls:MetroWindow x:Class="MetroDemo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:Controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
        Title="My Application"
        Width="960" Height="600"
        Icon="mahapps.metro.logo2.ico"
        ShowIconOnTitleBar="True"
        ShowTitleBar="True">
    <Grid />
</Controls:MetroWindow>

【讨论】：

@ShakedDahan，我建议您下载 MahApps 演示应用程序（我在答案中添加了它）并逐行检查您的代码。还要检查正确路径中的图标文件。所以我想通过这种方式你可以很容易地找到问题并解决它。请给我反馈。
我已经查过了，会不会是我的应用流向是 RightToLeft 的问题？
不，我使用 MahApp 从右到左和从左到右。检查您的图标（.ico 文件）。请在您的问题中添加窗口Xaml 属性。
我想你误会我说的那个图标了，我说的是这个：prntscr.com/curbm3
