如何在Windows Phone 8.1(C#,XAML)中隐藏状态栏?
在Windows Phone 8它被设置做shell:SystemTray.IsVisible="False"任何页面.但它没有Windows Phone 8.1

我是ASP/MVC的新手,我无法弄清楚如何div在HTML标记中链接到一个页面.这是纯HTML中的当前链接.我想完成这个,但是用剃刀语法

this.canSwitch = command.Label == "Yes" ? true : false;

我试过了:
var uiContext = TaskScheduler.FromCurrentSynchronizationContext();
Task.Factory.StartNew(() => {
MessageDialog md = new MessageDialog(question);
md.Commands.Add(new UICommand("Yes", CommandInvokedHandler));
md.Commands.Add(new UICommand("No", CommandInvokedHandler));
md.ShowAsync();
},

MessageDialog md = new MessageDialog(question);
md.Commands.Add(new UICommand("Yes", CommandInvokedHandler));
md.Commands.Add(new …Run Code Online (Sandbox Code Playgroud)
