c# - 使用 VS Styles 的 Mahapps 抛出 IOException

问题描述

我在我的 WPF 应用程序中使用 Mahapps Tabcontrol。当我使用默认样式时效果很好，如果我尝试在 App.xaml 中使用 VS 样式：

<Application x:Class="UI.App"
         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
         xmlns:system="clr-namespace:System;assembly=mscorlib"
         xmlns:vm="clr-namespace:UI.ViewModel"
         xmlns:controls="http://metro.mahapps.com/winfx/xaml/controls"
         xmlns:local="clr-namespace:UI"
         StartupUri="MainWindow.xaml">

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
            <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" />
            <!-- Accent and AppTheme setting -->
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Teal.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseDark.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/VS/Controls.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/VS/Colors.xaml" />
            <!-- Icons -->
            <ResourceDictionary x:Name="IconsDictionary" Source="Resources/Dictionary.xaml"/>
        </ResourceDictionary.MergedDictionaries>
        <system:Double x:Key="WindowTitleFontSize">16</system:Double>
        <FontFamily x:Key="HeaderFontFamily">Segoe UI</FontFamily>
        <vm:ViewModelLocator x:Key="MainLocator"/>
    </ResourceDictionary>
</Application.Resources>

...它抛出一个错误：IOException: Cannot locate resource 'styles/vs/controls.xaml'。

如果我从 App.xaml 中删除 VS/Styles 引用，则应用程序会编译。

解决方案

找到了解决办法！

首先，从 App.xaml 中删除 VS/Styles：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            
            <!-- MahApps.Metro resource dictionaries. Make sure that all file names are Case Sensitive! -->
            <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" />
            <!-- Accent and AppTheme setting -->
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/Teal.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/BaseDark.xaml" />
            <!-- Icons -->
            <ResourceDictionary x:Name="IconsDictionary" Source="Resources/Dictionary.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

其次，将其移至 Window.Resources 下的 MainWindow.xaml：

<Window.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/VS/Colors.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/VS/Styles.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Window.Resources>

在这里找到修复资源未在“Styles\VS\Colors.xaml”中定义
