Windows Phone 8.1中的命令欄

Question

如何在Windows Phone 8.1（Winprt）應用程序的C＃中創建輔助命令？

//WINRT:
CommandBar CommandBarObject = new CommandBar();
AppBarButton FirstBtn = new AppBarButton() { Icon = new BitmapIcon() { UriSource = new Uri("ms-appx:///Assets/first.png") } };
FirstBtn.Label = "First";
FirstBtn.Click += FirstBtn_Click;
FirstBtn.IsEnabled = true;

CommandBarObject.PrimaryCommands.Add(FirstBtn);
CommandBarObject.SecondaryCommands.Add(secondaryCommand);

現在如何制作此secondaryCommand ？

Answer 1

只需放在AppBarButton ：

 CommandBar CommandBarObject = new CommandBar();
 AppBarButton FirstBtn = new AppBarButton() { Icon = new BitmapIcon() { UriSource = new Uri("ms-appx:///Assets/first.png") } };
 FirstBtn.Label = "First";
 FirstBtn.Click += FirstBtn_Click;
 FirstBtn.IsEnabled = true;

 AppBarButton secondaryCommand = new AppBarButton() { Label = "Second", IsEnabled = true } };
 secondaryCommand.Click += FirstBtn_Click;

 CommandBarObject.PrimaryCommands.Add(FirstBtn);
 CommandBarObject.SecondaryCommands.Add(secondaryCommand);
