c#我可以在App.xml中使用Properties.settings值吗？

这是我在一个c#wpf项目中的

App.xaml

<Application x:Class="Test.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"
             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/REPLACEME.xaml" />
                <ResourceDictionary Source="pack://application:,,,/MahApps.Metro;component/Styles/Accents/REPLACEME.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

是否有任何方法可以将

Properties.settings.default

值添加到“REPLACEME”的位置

有没有办法将Properties.settings.default值添加到“REPLACEME”所在的位置

不，不使用内置的XAML编译器

您最好在

App.xaml.cs

中以编程方式添加资源字典：

public partial class App : Application
{
    protected override void OnStartup(StartupEventArgs e)
    {
        base.OnStartup(e);

        this.Resources.MergedDictionaries.Add(new ResourceDictionary() { Source = new Uri($"pack://application:,,,/MahApps.Metro;component/Styles/Accents/{Properties.settings.default}.xaml") });
    }
}

XAML是一种标记语言
