如果你想要修改ProgressBar的foreground 颜色，用下面的方法是不行的： ProgressBarIsIndeterminate= True Foreground= Aquamarine / 要修改ProgressBar的颜色，需要override默认主题资源字典中的如下值： ResourceDictionary.ThemeDictionaries ResourceDictionaryx:Key= Default x: String x:Key= ProgressBarIndetermin

　　

　　如果你想要修改ProgressBar的foreground 颜色，用下面的方法是不行的：

<ProgressBar IsIndeterminate="True" Foreground="Aquamarine" />

　　要修改ProgressBar的颜色，需要override默认主题资源字典中的如下值：

<ResourceDictionary.ThemeDictionaries>
    <ResourceDictionary x:Key="Default">
        <x:String x:Key="ProgressBarIndeterminateForegroundThemeBrush">Red</x:String>
    </ResourceDictionary>
</ResourceDictionary.ThemeDictionaries>

　　可以将这个override添加到App.xaml中，或者创建一个新的资源字典，并合并到App.xaml中：

　　A、直接添加到App.xaml中，如下代码：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.ThemeDictionaries>
            <ResourceDictionary x:Key="Default">
                <x:String x:Key="ProgressBarIndeterminateForegroundThemeBrush">Red</x:String>
            </ResourceDictionary>
        </ResourceDictionary.ThemeDictionaries>
        <ResourceDictionary.MergedDictionaries>

            <!-- 
                Styles that define common aspects of the platform look and feel
                Required by Visual Studio project and item templates
                -->
            <ResourceDictionary Source="Common/StandardStyles.xaml"/>
        </ResourceDictionary.MergedDictionaries>

    </ResourceDictionary>
</Application.Resources>

　　B、创建了一个CustomStyles.xaml，并将该文件合并到App.xaml中：

<Application
    x:Class="Sample.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Common/StandardStyles.xaml" />
                <ResourceDictionary Source="Common/CustomStyles.xaml" />
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

　　CustomStyles.xaml:

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
    <!-- Global Overrides -->
    <ResourceDictionary.ThemeDictionaries>
        <ResourceDictionary x:Key="Default">
            <x:String x:Key="ProgressBarIndeterminateForegroundThemeBrush">Red</x:String>
        </ResourceDictionary>
    </ResourceDictionary.ThemeDictionaries>
</ResourceDictionary>
