UWP:如何启动位于特定目录中的 exe 文件? [英] UWP: how to start an exe file that is located in specific directory?

问题描述

我正在尝试从 UWP 应用程序启动位于 C:/Program Files (x86)/App 中的 exe.我该怎么做.

I am trying to start an exe that is located in C:/Program Files (x86)/App from UWP app. How can I do this.

我可以使用 UWP 的 Windows 桌面扩展启动 exe 文件，添加隐藏复制代码

I can start exe file by using Windows Desktop extension for UWP, add Hide Copy Code

<Extensions>
        <desktop:Extension Category="windows.fullTrustProcess"          Executable="Assetsapp.exe" />
</Extensions>

到 Package.appmanifest 并调用它

to Package.appmanifest and call this

await FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync();

在主类中.但是我需要将 app.exe 添加到项目的 Assets 目录
我的问题是，如果 exe 文件位于其他目录中，如何在不准确添加 exe 文件的情况下启动它.
谢谢

in main class. But I need to add app.exe to Assets directory of project
My question is if exe file is located in other directory, how can I start it without adding exactly the exe file.
Thanks

推荐答案

今天我编写了一个程序，可以从 UWP 成功启动任何 .exe 程序.想分享过程以造福他人.这是对 stefan Wick MSFT 的回答的补充.首先需要更新 package.appmanifest.这是我在 package.appmanifest 中的内容:

Today I wrote a program to successfully launch any .exe programs from UWP. Want to share the process for the benefit of others. This is in addition to the answer by stefan Wick MSFT. First the package.appmanifest needs to be updated. This is what I have in package.appmanifest:

<?xml version="1.0" encoding="utf-8"?>

      </uap:VisualElements>

        <Extensions>

          <desktop:Extension Category="windows.fullTrustProcess" Executable="AssetsLauncher.exe" >
          <desktop:FullTrustProcess>
            <desktop:ParameterGroup GroupId="ChromeGroup" Parameters="chrome.exe"/>
            <desktop:ParameterGroup GroupId="WordGroup" Parameters="WINWORD.exe"/>
          </desktop:FullTrustProcess>
          </desktop:Extension>
        </Extensions>

    </Application>
  </Applications>

  <Capabilities>

    <Capability Name="internetClient"/>
    <rescap:Capability Name="runFullTrust" />

  </Capabilities>

</Package>

标签中的代码负责启动可执行文件.带有 <Capabilities> 标签的代码添加了启动可执行文件的能力或权限.像 runFullTrust 这样的限制性能力在它下面有绿线.这不是错误，程序将运行而不会出现任何错误.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:

The code within the <Extensions> tag is the one responsible for launching the executable files. The code with <Capabilities> tag add capability or permission to launch the executable.The restrictive capabilities like runFullTrust is having green green line below it. It is not a error and program will run without any error. The Launcher.exe in the above code is a console app. I write the code in the text editor and created Launcher.exe from it. The code of the Launcher.exe is this:

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.不允许 UWP 启动 .exe 应用程序.但是 UWP 应用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:

Saved this Launcher.exe console app in Assets folder of the UWP project. UWP is not allowed to launch .exe apps. But UWP app calls this code to launch any .exe program. The GroupId ChromeGroup is used to launch chrome browser by passing chrome.exe parameter to the Launcher.exe. The GroupId WordGroup is used to launch MS Word by passing WINWORD.exe parameter to Launcher.exe. The code to pass the parameter to Launcher.exe is :

`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 作为参数来做到这一点.Api 在 Windows.ApplicationModel 命名空间下可用.

On the click of a button above Api pass on the name of the exe file to Launcher.exe program. It do this by accepting GroupId as parameter. The Api is available under Windows.ApplicationModel NameSpace.

您要启动的可执行文件可能未安装在系统上.它可能不会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.

The executable you want to launch may not be installed on system. It may not be packaged with your application in Assets folder. Than you can give full path of the executable in the Parameters attribute.
