  WPF界面与逻辑处理

  界面交互对象、界面渲染、业务逻辑控制、事件驱动与数据驱动。WPF在接受Windows消息会直接命中的窗口句柄，然后通过路由进入到内部对象（命中）。在业务逻辑层面WPF不直接操作控件，隔山大牛（通过数据建模MVVM来获取数据)。

实现了数据Binding、Command指令、NotifyPropertyChanged（控件属性变更会传递给对象）

public class ShowNumModel:INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler? PropertyChanged;
        private string content;
        public string Content
        {
            get { return content; }
            set 
            { 
                content = value;
                this.PropertyChanged?.Invoke(this, new PropertyChangedEventArgs("content"));
            }
        }
        public ShowNumModel(string content)
        {
            this.Content = content;  
        }
    }

public class CommandHelper : ICommand
    {
        public event EventHandler? CanExecuteChanged;

        public Action<object> DoExecute { get; set; }

        public bool CanExecute(object? parameter)
        {
            return true;
        }

        public void Execute(object? parameter)
        {
            DoExecute?.Invoke(parameter);
        }

        public CommandHelper(Action<object> doExecute)
        {
            DoExecute = doExecute;
        }
    }

 public class MainWindowsModel
    {
        public event PropertyChangedEventHandler? PropertyChanged;

        public string Title { get; set; } = "AlbertZhao";

        public ButtonModel BtnModel { get; set; } = new ButtonModel();

        public CommandHelper ButtonClickCommand
        {
            get => new CommandHelper(DoButtonClick); 
        }     

        private void DoButtonClick(object obj)
        {
            ButtonModel button = obj as ButtonModel;
            var test = button.Content;
            // 实现界面时间的实时刷新
            Task.Run(() =>{

                while (true)
                {
                    // 这一句等同于async ()=> await Task.Delay(100);
                    // Task.Delay(100).GetAwaiter().GetResult();
                    this.BtnModel.Content = DateTime.Now.ToString();
                }
            });

        }

    }
