WPF 简单页面切换示例

原理比较简单，但是有个坑，为了使界面能够正确更新，记得使用 INotifyPropertyChanged 接口来实现属性更改通知。

namespace PageTest
{
    /// 
    /// Interaction logic for MainWindow.xaml
    /// 
    [AddINotifyPropertyChangedInterface]
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            DataContext = this;
        }
        object curMain;
        public object CurMain { get => curMain; set => curMain = value; }
        private void Button_Click(object sender, RoutedEventArgs e)
        {
            CurMain = new Page1();
        }
        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            CurMain = new Page2();
        }
    }
}
