从另一个运行的metro应用程序启动一个已安装的metro应用程序

hii

我有一个地铁应用程序，我想从中导航或说启动另一个已经以编程方式安装在ma pc上的地铁应用程序。完成后我新推出的应用程序我也想回到正在运行的应用程序。

I have one metro app from which i want to navigate to or say launch another metro app which is already installed on ma pc programmatically.After i am done with newly launched app i also want to get back to running app.

我正在使用：

Windows.Storage.StorageFile file1 =等待Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync（@" NewApp.exe"）; 

Windows.Storage.StorageFile file1 = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync(@"NewApp.exe"); 

等待Windows.System.Launcher.LaunchFileAsync（file1）;

await Windows.System.Launcher.LaunchFileAsync(file1);

给我文件not Found例外。

which gives me file not Found exception .

这里是地铁应用程序我给.exe扩展名。它是正确的还是需要其他扩展名。

Here for metro app i am giving .exe extension. is it correct or other extension is required.

Plz帮助我..

谢谢你的支持
