在这个示例中,我们使用了三个视图模型:`LoginViewModel`,`HomeViewModel`和`ViewModelBase`,其中`LoginViewModel`和`HomeViewModel`继承自`ViewModelBase`。`LoginViewModel`用于处理登录逻辑,`HomeViewModel`用于处理主页逻辑。`ViewModelBase`实现了`INotifyPropertyChanged`接口,用于在属性更改时通知视图。
我们还使用了三个服务:`ILoginService`,`IRedirectService`和`LoginRedirectService`。`ILoginService`用于处理登录逻辑,`IRedirectService`用于处理跳转逻辑,`LoginRedirectService`实现了`IHostedService`接口,用于在应用程序启动时将用户重定向到登录界面。
最后,我们使用了`RelayCommand`类实现了`ICommand`接口,以便我们可以在视图中使用命令。

在以上代码中,MainWindowViewModel类包含了登录窗口的数据和行为,其中LoginCommand命令用于处理登录操作。当用户点击登录按钮时,LoginAsync方法被执行,该方法首先验证输入是否合法,然后对密码进行哈希处理,并模拟发送登录请求。如果请求成功,程序会跳转到主窗口,否则会提示错误信息。
MainViewModel类则包含了主窗口的数据和行为,其中LogoutCommand命令用于处理注销操作。当用户点击注销按钮时,Logout方法被执行,该方法会关闭主窗口,并跳转回登录窗口。
RelayCommand类是一个通用的命令实现,用于将委托转换为ICommand接口。
LoginHostedService类继承自IHostedService接口,用于在应用程序启动时显示登录窗口,并在应用程序关闭时关闭登录窗口。
App类则用于配置和启动应用程序,其中使用了Microsoft.Extensions.Hosting和Microsoft.Extensions.DependencyInjection库来实现依赖注入和应用程序生命周期管理。
