我有一个问题,我有一个shell页面,上面有几个
shell内容
链接,如下所示:

<?xml version="1.0" encoding="utf-8" ?>
<Shell xmlns="http://xamarin.com/schemas/2014/forms"
       xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

       x:Class="MyApp.SideMenuItems" BackgroundColor="#212121"
       FlyoutBackgroundColor="#212121"
       x:Name="MainShell">

    <Shell.FlyoutHeader>

    </Shell.FlyoutHeader>

    <Shell.TitleView>
        <Image Source="Title_Dark.png" HeightRequest="30" VerticalOptions="CenterAndExpand" />
    </Shell.TitleView>

    <Shell.ItemTemplate>
        <DataTemplate>
            <StackLayout HorizontalOptions="StartAndExpand" Orientation="Horizontal" Padding="30, 15, 0, 15">

    <FlyoutItem Title="SideNav"
                Shell.TabBarIsVisible="False"
                FlyoutDisplayOptions="AsMultipleItems">
        <ShellContent Title="Home" Icon="Home_Dark.png" IsTabStop="true" ContentTemplate="{DataTemplate local:HomePage}"/>
        <ShellContent Title="Search" Icon="Search_Dark.png" IsTabStop="true" ContentTemplate="{DataTemplate local:HomePage}" />
        <ShellContent Title="Settings" Icon="Settings_Dark.png" IsTabStop="true" ContentTemplate="{DataTemplate local:HomePage}" />
    </FlyoutItem>
</Shell>

只是现在我想用C#添加
ShellContent
,但我不知道如何才能做到这一点

有什么建议吗

只是现在我想使用C#添加ShellContent,但我不知道如何才能做到这一点

如果您想在C#中执行此操作,可以尝试下面的代码

public partial class AppShell : Xamarin.Forms.Shell
{
    public AppShell()
    {
        InitializeComponent();
        ShellSection shell_section = new ShellSection
        {
            Title = "home",
        };

        shell_section.Items.Add(new ShellContent() { Content = new ItemsPage() });

        ShellSection shell_section1 = new ShellSection
        {
            Title = "about",


        };

        shell_section1.Items.Add(new ShellContent() { Content = new AboutPage() });

        myshell.Items.Add(shell_section);
        myshell.Items.Add(shell_section1);
    }
}
myshell是Shell的名称

x:Name="myshell"
结果:

        myshell.Items.Add(shell_section1);
    }
}

x:Name="myshell"
结果:


就像你给了一个名字
x:name=“MainShell”
,为什么不对你想在C#中访问的ShellContent项目做同样的事情呢?就像你给了一个名字
