< Extensions>中的代码tag是负责启动可执行文件的标签.包含<功能>的代码标签添加启动可执行文件的功能或权限.像runFullTrust这样的限制性功能在它下面有绿绿线.这不是错误,程序将运行没有任何错误.上面代码中的Launcher.exe是一个控制台应用程序.我在文本编辑器中编写代码并从中创建Launcher.exe. Launcher.exe的代码是这样的：

using System;  
using System.IO;   
using System.Diagnostics;                                                                         
using System.Reflection;
    class Program
    {
    static void Main(string []args)
    {
    try
    {

    if(args.Length!=0)
    {
    string executable=args[2];
   /*uncomment the below three lines if the exe file is in the Assets  
    folder of the project and not installed with the system*/         
    /*string path=Assembly.GetExecutingAssembly().CodeBase;
    string directory=Path.GetDirectoryName(path);
    process.Start(directory+""+executable);*/
    Process.Start(executable);
    }
    }
    catch(Exception e)
    {
    Console.WriteLine(e.Message);
    Console.ReadLine();
    }

    }
    }

将此Launcher.exe控制台应用程序保存在UWP项目的Assets文件夹中. UWP不允许启动.exe应用程序.但是UWP应用程序调用此代码来启动任何.exe程序. GroupId ChromeGroup用于通过将chrome.exe参数传递给Launcher.exe来启动Chrome浏览器. GroupId WordGroup用于通过将WINWORD.exe参数传递给Launcher.exe来启动MS Word.将参数传递给Launcher.exe的代码是：

`private async void Button_Click(object sender,RoutedEventArgs e)
{
await FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync("ChromeGroup");
await FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync("WordGroup");
}`

单击Api上方的按钮,将exe文件的名称传递给Launcher.exe程序.它通过接受GroupId作为参数来完成此操作. Api在Windows.ApplicationModel NameSpace下可用.

编辑：

您要启动的可执行文件可能未安装在系统上.它可能无法与您的应用程序一起打包在Assets文件夹中.您可以在Parameters属性中提供可执行文件的完整路径.
