前言

虽然写的大部分都是不联网项目，上位机的项目一般写好了就不动了。但是说不定以后就需要自动更新呢。桌面程序不像网页，联网就能用。而是要进行版本号判断进行更新的。

运行环境

• Visual Studio 2022
• .net core 8.0
• IIS

ClickOnce（Visual Studio 程序发布）

毕竟是微软官方的部署方式，应该是挺简单的

ClickOnce 安全性和部署

快速创建软件安装包-ClickOnce

IIS新建文件夹

C# 控制台测试

新建一个简单的控制台程序进行测试

安装测试

这里报错是因为没有签名。

安装成功，但是默认路径是C盘，有点尬尴

Choose install path for ClickOnce application during setup

更新测试

卸载

直接卸载即可

新建一个WPF项目

</Window>

    /// <summary>/// Interaction logic for MainWindow.xaml/// </summary>public partial class MainWindow : Window{public MainWindow(){InitializeComponent();AutoUpdateTest();}public void AutoUpdateTest(){Assembly assembly = Assembly.GetEntryAssembly();LabelVersion.Text = $"Current Version : {assembly.GetName().Version}";//显示版本号AutoUpdater.AppTitle = "升级更新";Thread.CurrentThread.CurrentCulture =Thread.CurrentThread.CurrentUICulture = CultureInfo.CreateSpecificCulture("zh");AutoUpdater.LetUserSelectRemindLater = true;AutoUpdater.RemindLaterTimeSpan = RemindLaterFormat.Minutes;AutoUpdater.RemindLaterAt = 1;AutoUpdater.ReportErrors = true;DispatcherTimer timer = new DispatcherTimer { Interval = TimeSpan.FromMinutes(2) };//定时去检测更新根据自己业务需求timer.Tick += delegate { AutoUpdater.Start("http://localhost:10911/Updates/AutoUpdaterStarter.xml"); };timer.Start();}private void Button_Click(object sender, RoutedEventArgs e){AutoUpdater.Start("http://localhost:10911/Updates/AutoUpdaterStarter.xml");}}

代码封装

这里用到了之前的代码

简单使用

总结

还是AutoHelper好使，简单好用。AutoHelper的UpdateLog.html就自己加描述了，就是简单的html语言。
