1. MainPage.xmal

             
                  
                       
                        
                    
                   
                       
                        
                    
                   
                       
                        
                    
               
              
                  
                       
        
         Item 1
                        
        
         Item 2
                        
        
         Item 3
                        
        
         Item 4
                        
        
         Item 5
                    
                   
                   
                   
                   
                   
               
              
          
     

1.1 导航栏 （就是 标签栏）

1.2 listview

                     
      
       Item 1
                      
      
       Item 2
                      
      
       Item 3
                      
      
       Item 4
                      
      
       Item 5
                  
     

1.3 Button

按 F12 生成点击事件代码，（async 异步）

private async void Button_Click_1(object sender, RoutedEventArgs e)        {            await new Windows.UI.Popups.MessageDialog("Hello World").ShowAsync();        }        private async void Button_Click_2(object sender, RoutedEventArgs e)        {            var dialog = new ContentDialog()            {                Title = "提示",                Content = "你确认要退出该页面吗?",                PrimaryButtonText = "确定",                SecondaryButtonText = "取消",                FullSizeDesired = false,            };            await dialog.ShowAsync();        }        private async void button_Click(object sender, RoutedEventArgs e)        {                MediaElement mediaElement = new MediaElement();                var synth = new Windows.Media.SpeechSynthesis.SpeechSynthesizer();                Windows.Media.SpeechSynthesis.SpeechSynthesisStream stream = await synth.SynthesizeTextToStreamAsync("I Love U");                mediaElement.SetSource(stream, stream.ContentType);                mediaElement.Play();        }        private async void SubmitButton_Click(object sender, RoutedEventArgs e)        {            // Call app specific code to submit form. For example:            // form.Submit();            Windows.UI.Popups.MessageDialog messageDialog =                new Windows.UI.Popups.MessageDialog("Thank you for your submission.");            await messageDialog.ShowAsync();        }
