如何在Windows 10 IoT

我想在我的Windows 10 IoT(Raspberry Pi 3)版本14986(或更高版本)上运行“Launcher App”。启动器应用程序应该基本上只有两个按钮来启动(或切换到)已部署在设备上的其他应用程序。我想知道是否有人知道如何启动应用程序(来自C#)?

我查看了Windows.System.Launcher.LaunchUriAsync API,但我不知道要传递什么(我在选项下测试了一些URI和TargetApplicationPackageFamilyName,没有运气(调用时没有任何反应)方法)。

示例(不起作用):

    private void button_Click(object sender, RoutedEventArgs e)
    {
        Task.Run(async () =>
        {
            var options = new LauncherOptions();
            options.TargetApplicationPackageFamilyName = "27ad8aa6-8c23-48bd-9633-e331740e6ba7_mr3ez18jctte6!App";

            var uri = new Uri("about:blank");

            await Windows.System.Launcher.LaunchUriAsync(uri, options);
        });
    }

您可以在Microsoft Code上找到答案。有一个样本:

https://code.msdn.microsoft.com/windowsapps/How-to-launch-an-UWP-app-5abfa878

在此示例中,您可以找到Launcher代码:

private async void RunMainPage_Click(object sender, RoutedEventArgs e) 
{ 
    await LaunchAppAsync("test-launchmainpage://HostMainpage/Path1?param=This is param"); 
} 

private async void RunPage1_Click(object sender, RoutedEventArgs e) 
{ 
    await LaunchAppAsync("test-launchpage1://Page1/Path1?param1=This is param1&param1=This is param2"); 
} 

private async Task LaunchAppAsync(string uriStr) 
{ 
    Uri uri = new Uri(uriStr); 
    var promptOptions = new Windows.System.LauncherOptions(); 
    promptOptions.TreatAsUntrusted = false; 

    bool isSuccess = await Windows.System.Launcher.LaunchUriAsync(uri, promptOptions); 

    if (!isSuccess) 
    { 
        string msg = "Launch failed"; 
        await new MessageDialog(msg).ShowAsync(); 
    } 
}

设置技巧,在要启动的应用程序上指定Windows协议,并在LaunchApp URI中指定。
