using Avalonia;
using Avalonia.Controls.ApplicationLifetimes;
using Avalonia.Markup.Xaml;
using Avalonia.Media;

namespace AvaloniaXinChuangDemo;

public partial class App : Application
{
    public override void Initialize()
    {
        AvaloniaXamlLoader.Load(this);
        // 全局字体回退：文泉驿黑体 → Noto思源黑体 → 思源黑体 → 黑体
        Resources["FontFamily"] = new FontFamily("WenQuanYi Zen Hei,Noto Sans CJK SC,Source Han Sans CN,SimHei");
    }

    public override void OnFrameworkInitializationCompleted()
    {
        if (ApplicationLifetime is IClassicDesktopStyleApplicationLifetime desktop)
        {
            desktop.MainWindow = new MainWindow
            {
                DataContext = new MainWindowViewModel()
            };
        }
        base.OnFrameworkInitializationCompleted();
    }
}

5. MainWindow.axaml

<Window
    x:Class="AvaloniaXinChuangDemo.MainWindow"

        <vm:MainWindowViewModel />
    </Window.DataContext>

    <StackPanel Margin="30" Spacing="16">
        <TextBlock Text="Avalonia 信创演示窗口" FontSize="24"/>
        <TextBlock Text="中文测试：银河麒麟、统信UOS、龙芯/飞腾/兆芯" FontSize="16"/>

        <Button Content="点我测试MVVM" Command="{Binding TestCmd}" />
        <TextBlock Text="{Binding Message}" FontSize="16" Foreground="#2255bb"/>
    </StackPanel>
</Window>

6. MainWindow.axaml.cs

using Avalonia;
using Avalonia.Controls;
using Avalonia.Markup.Xaml;

namespace AvaloniaXinChuangDemo;

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

7. MainWindowViewModel.cs（MVVM ViewModel）

using CommunityToolkit.Mvvm.ComponentModel;
using CommunityToolkit.Mvvm.Input;

namespace AvaloniaXinChuangDemo;

public partial class MainWindowViewModel : ObservableObject
{
    [ObservableProperty]
    private string _message = "等待点击按钮";

    [RelayCommand]
    private void Test()
    {
        Message = $"当前时间：{DateTime.Now:yyyy-MM-dd HH:mm:ss}";
    }
}

编译 & 发布命令

# 本地调试运行
dotnet run

# 兆芯/海光 linux-x64 NativeAOT 单文件发布
dotnet publish -c Release -r linux-x64 --self-contained true /p:PublishAot=true

# 飞腾/鲲鹏 arm64
dotnet publish -c Release -r linux-arm64 --self-contained true /p:PublishAot=true

# 龙芯 loongarch64
dotnet publish -c Release -r linux-loongarch64 --self-contained true /p:PublishAot=true

部署到国产系统前置依赖（银河麒麟 / 统信UOS）

sudo apt install libgl1-mesa-dev libgbm-dev libinput-dev libx11-dev libxi-dev

⚠️ 登录系统时选择 X11会话，不要Wayland，规避剪贴板、窗口拖拽异常

可选扩展（按需加，全部MIT）

• Material.Avalonia 表单控件
• Material.Icons.Avalonia 字体图标
• Avalonia.Controls.TreeDataGrid 树形表格（免费旧版）

如果你需要，我可以再增加：

1. DataGrid 示例代码（绑定列表数据）
2. TreeDataGrid 树形表格示例
3. 打包为deb安装包脚本，直接在UOS/麒麟安装
