如何在wpf xaml中设置textbox的提示文本和提示文本颜色？

我想在xaml文本框中创建提示文本并设置提示文本颜色。有没有办法直接在xaml文件中设置文本框中的提示文本和提示文本颜色？请告诉我怎么走。

我使用MaterialDesignThemes。下载NuGet并按如下所示提供给我们：

xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes" 

<TextBox materialDesign:HintAssist.Hint="Floating Hint" Style="{StaticResource MaterialDesignFloatingHintTextBox}" VerticalAlignment="Center"/>

您还需要在App.xaml中进行以下更改

<ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Dark.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml" />
            <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.DeepPurple.xaml" />
        </ResourceDictionary.MergedDictionaries>
