Question

我在新窗口中更新颜色时遇到问题。资源在App.xml中

<Application
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:vsm="clr-namespace:System.Windows;assembly=System.Windows"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" x:Class="EOS_Toolkit.App"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <SolidColorBrush x:Key="EOS_RED" Color="#FF619C1A"/>
        <SolidColorBrush x:Key="EOS_GRAY" Color="#FF666366"/>
        <SolidColorBrush x:Key="NORMAL_TEXT" Color="#FF000000"/>
        <SolidColorBrush x:Key="DESC_TEXT" Color="#FF7C7C7C"/>
        <SolidColorBrush x:Key="MAIN_BACKGROUND" Color="#FFFFFFFF"/>

我按类加载模板并设置它

 def = templates[name];

                if (def.eos_red != null) { Application.Current.MainWindow.Resources["EOS_RED"] = (SolidColorBrush)(new BrushConverter().ConvertFrom(def.eos_red)); }
                if (def.eos_gray != null) { Application.Current.MainWindow.Resources["EOS_GRAY"] = (SolidColorBrush)(new BrushConverter().ConvertFrom(def.eos_gray)); }
                if (def.normal_text != null) { Application.Current.MainWindow.Resources["NORMAL_TEXT"] = (SolidColorBrush)(new BrushConverter().ConvertFrom(def.normal_text)); }
                if (def.desc_text != null) { Application.Current.MainWindow.Resources["DESC_TEXT"] = (SolidColorBrush)(new BrushConverter().ConvertFrom(def.desc_text)); }
                if (def.main_background != null) { Application.Current.MainWindow.Resources["MAIN_BACKGROUND"] = (SolidColorBrush)(new BrushConverter().ConvertFrom(def.main_background)); }

我在使用进度条加载新窗口时有时会在应用程序中进行。

Load loading = new Load(); // okno s progressbarem
            loading.Owner = this;
            loading.Closed += loading_done;
            this.IsEnabled = false;
            loading.Show();
            _Plugins[Convert.ToString(sender.lab_name.Text)].Load(loading.prg_load);
            loading.Hide();
            this.IsEnabled = true;

这里是新窗口的xaml

<Window x:Class="EOS_Toolkit.Load"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Načítaní..." Height="81" Width="300" ResizeMode="NoResize" ShowInTaskbar="False" WindowStartupLocation="CenterOwner" WindowStyle="None" AllowsTransparency="True" Topmost="True" Background="{DynamicResource MAIN_BACKGROUND}">
    <Window.Effect>
        <DropShadowEffect/>
    </Window.Effect>
    <Border BorderBrush="{DynamicResource EOS_RED}" BorderThickness="2">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="Auto"/>
                <RowDefinition Height="Auto"/>
                <RowDefinition/>
            </Grid.RowDefinitions>
            <Rectangle Fill="{DynamicResource EOS_RED}" Margin="0" Grid.Row="0" Stroke="{DynamicResource EOS_RED}" Height="20" VerticalAlignment="Top"/>
            <Label Content="Načítaní..." Margin="0" Grid.Row="1" VerticalAlignment="Top" HorizontalAlignment="Center" FontFamily="Arial" FontSize="24" Foreground="{DynamicResource NORMAL_TEXT}" />
            <ProgressBar x:Name="prg_load" Height="10" Margin="5,0" Grid.Row="2" VerticalAlignment="Top" Foreground="{DynamicResource EOS_RED}" Background="#33000000" BorderBrush="{x:Null}"/>

        </Grid>
    </Border>
</Window>

问题是当我加载temlate并更改值时，应用程序中的每种颜色都会更改，但此窗口仍为默认颜色。有人可以帮忙吗？感谢
