如何在.Net MAUI 中为 ContentPage 标题添加样式？

我正在使用 .NET MAUI 创建桌面应用程序。

在这里，我有一个ContentPage与标题My title.

<ContentPage
    x:Class="MAUI.Desktop.Pages.PlanningPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    Title="My title">
....

Its title is aligned left by default, do you know how to align it to the center of the page? If possible, I also want to add more style to it too.

编辑：建议的解决方案

• 我忘了提及我的页面已被考虑NavigationPage。所以，这是我的解决方案：

<ContentPage
    x:Class="MAUI.Desktop.Pages.PlanningPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
>
 <NavigationPage.TitleView>
        <Label
            x:Name="pageTitleView"
            HorizontalTextAlignment="Center"
            Text="My title"/>
</NavigationPage.TitleView>
......

在代码隐藏中xaml.cs file:

 protected override void OnSizeAllocated(double width, double height)
 {
     base.OnSizeAllocated(width, height);
     pageTitleView.WidthRequest = width;
 }

• 如果您正在与Shell app，你可以按照来自@mm8的回答 https://stackoverflow.com/a/74657045/12020710

你可以定义你自己的TitleView:

<ContentPage                          x:Class="MAUI.Desktop.Pages.PlanningPage"
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    Title="Planification">
    <Shell.TitleView>
        <Grid>
            <Label Text="My Title" HorizontalOptions="Center" VerticalOptions="Center" />
        </Grid>
    </Shell.TitleView>
    ...
