现在我的应用程序中有一些隐式样式的 TabItem。我想在我的应用程序中添加“夜间模式”并更改我的风格。我该怎么办？

您可以使用合并字典来做到这一点。将所有“正常”样式放入字典中，并默认将其添加到应用程序资源中：

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Styles/Normal.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

然后您可以删除当前字典并动态加载另一个字典：

private void ChangeStyles()
{
    App.Current.Resources.MergedDictionaries.Clear();

    StreamResourceInfo resInfo = App.GetResourceStream(new Uri("Styles/NewStyles.xaml", UriKind.Relative));
    XDocument xaml = XDocument.Load(resInfo.Stream);
    ResourceDictionary resource = XamlReader.Load(xaml.ToString()) as ResourceDictionary;

    App.Current.Resources.MergedDictionaries.Add(resource);
}

You can do this with merged dictionaries. Put all your "normal" styles in a dictionary and add it to the app resources by default:

<Application.Resources>
    <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="Styles/Normal.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>

Then you can remove the current dictionary and load another one dynamically:

private void ChangeStyles()
{
    App.Current.Resources.MergedDictionaries.Clear();

    StreamResourceInfo resInfo = App.GetResourceStream(new Uri("Styles/NewStyles.xaml", UriKind.Relative));
    XDocument xaml = XDocument.Load(resInfo.Stream);
    ResourceDictionary resource = XamlReader.Load(xaml.ToString()) as ResourceDictionary;

    App.Current.Resources.MergedDictionaries.Add(resource);
}

阿方索的想法是对的……
但你必须在 WPF 中这样做

App.Current.Resources.MergedDictionaries.Clear(); 
Uri uri = new Uri("/Resources/GlassButton5Night.xaml", UriKind.Relative);
var resDict = Application.LoadComponent(uri) as ResourceDictionary;
App.Current.Resources.MergedDictionaries.Add(resDict);

并且你必须确保在正确的级别重置你的 MergedDictionaries

Alfonso was right in idea...
but you have to do it like this in WPF

App.Current.Resources.MergedDictionaries.Clear(); 
Uri uri = new Uri("/Resources/GlassButton5Night.xaml", UriKind.Relative);
var resDict = Application.LoadComponent(uri) as ResourceDictionary;
App.Current.Resources.MergedDictionaries.Add(resDict);

And you have make sure you reset your MergedDictionaries at the right level
