如何从VSPackage的当前运行Visual Studio安装路径 [英] How get the current running Visual Studio installation path from VSPackage

问题描述

我创建了一个 VSPackage的应一些XML架构文件复制到Visual Studio的安装路径为： VS％安装路径％\Xml\\ 。\\Schemas

I've created a VSPackage which should copy some XML schema files to Visual Studio's installation path: %VS install path% \Xml\Schemas.

我有多个视觉工作室安装在我的机器上：

I have multiple Visual Studios installed on my machine:

• 的Visual Studio 2013专业版。


• 的Visual Studio 2015社区版。


• 的Visual Studio Express版。

我需要检测的路径到的Visual Studio 从中我的 VSPackage的正在执行其命令。

I need to detect the path to the Visual Studio from which my VSPackage is executing its command.

我怎样才能在当前运行Visual Studio的安装路径的包？

推荐答案

首先，我与卡洛斯同意在延期不应该需要提升权限的特定点。但是，这并不意味着，你的问题不能得到解决;我只想建议做另一种方式...

First, I agree with Carlos in that particular point that an extension should never require elevated priviledges. But that does not mean, your problem cannot be solved; I would just suggest to do it in another way...

我有一个类似的问题，我的扩展之一;我一直在寻找这不会需要Windows Installer安装程序，但对于纯粹的VSIX包工作的解决方案。我通过创建一个小型控制台应用程序，这是我用我的包组装引用解决它。我添加应用程序清单的控制台应用程序，允许我请求所需的执行水平;例如：

I had a similiar issue with one of my extensions; and I was looking for a solution which would not require a Windows installer setup, but work for pure VSIX packages. I solved it by creating a small console application, which I referenced by my package assembly. I added an application manifest to the console application, allowing me to request the required execution level; for instance:

<requestedExecutionLevel level="requireAdministrator" uiAccess="false" />

控制台应用程序看起来像...

The console application looks like...

public class HelperExe
{
    public static int Main(params string[] args)
    {
        // TODO: 
    }
}

控制台应用程序将做到这一点需要提升权限的工作。包创建使用过程类的新进程;可以从限定装配可获得image's文件路径（因为这可能是一个随机的路径，如果该包从VSIX安装）。

The console application will do the work that requires elevated priviledges. The package creates a new process using the Process class; the image´s file path can be obtained from the defining assembly (because this might be a random path, if the package is installed from VSIX).

var consoleAssemblyLocation = new Uri(typeof(HelperExe).Assembly.CodeBase);
var file = new FileInfo(consoleAssemblyLocation.LocalPath);
if (file.Exists)
{
    var consoleProcess = new Process 
    {
        StartInfo = new ProcessStartInfo(file.FullName)
        {
            CreateNoWindow = true
        }
    };

    consoleProcess.Start();
    var timeout = (int)TimeSpan.FromMinutes(5).TotalMilliseconds;
    consoleProces.WaitForExit(timeout);
}

由于该清单将包括 UAC 来提升的过程...这也有漂亮的副作用，用户可以取消操作。请确保您的扩展可以处理...

Since the manifest will involve the UAC to elevate the process... this has also the nice side-effect, that the user can cancel that operation. Make sure that your extension can handle that...

视觉Studio's安装文件夹，可以从注册表中读取;您可以通过一个命令行参数传递所获得的路径控制台应用程序。我做了这样的...

Visual Studio´s installation folder can be read from the registry; you can pass the obtained path to the console application via a commandline argument. I did it like this...

static string GetVisualStudioInstallationFolder(string visualStudioVersion)
{
    string subKeyName = string.Format(
        CultureInfo.InvariantCulture, 
        @"Software\Microsoft\VisualStudio\{0}_Config", 
        visualStudioVersion);

    using (RegistryKey key = Registry.CurrentUser.OpenSubKey(subKeyName))
    {
        if (key != null)
        {
            return (string)key.GetValue("ShellFolder");
        }
    }

    return null;
}
