查找Visual Studio 2010扩展的主目录 [英] Finding the home directory for a Visual Studio 2010 extension

问题描述

我正在对Visual Studio向导进行更改，该向导从模板创建项目，并且需要向该程序集添加对程序集的引用，该程序集也位于扩展目录中.所以我需要设置<hintpath>.

I am making changes to a Visual Studio wizard that creates a project from a template, and needs to add a reference to an assembly to the project that also lives in the extension directory. So I need to set the <hintpath>.

我无法弄清正在运行的VS扩展如何发现其扩展目录，该目录是这样的目录:

I have not been able to figure out how a running VS extension can discover its extension directory, which is a directory name like this:

％USERPROFILE％\ AppData \ Local \ Microsoft \ VisualStudio \ 10.0 \ Extensions \ myCompany \ myExtension

%USERPROFILE%\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\myCompany\myExtension

使用System.Reflection.Assembly.GetExecutingAssembly().CodeBase会产生:

"C:\ Windows \ Microsoft.Net \ assembly \ GAC_MSIL \ myCompany.myExtension \ v4.0_1.0.0.0__936015a19c3638eb \ myCompany.myExtension.dll"

"C:\Windows\Microsoft.Net\assembly\GAC_MSIL\myCompany.myExtension\v4.0_1.0.0.0__936015a19c3638eb\myCompany.myExtension.dll"

不幸的是，没有帮助.使用GetCallingAssembly()并不更好，它指向MSIL_GAC中的另一个目录.

Unfortunately, not helpful. Using GetCallingAssembly() is no better--it points at another directory in the MSIL_GAC.

是否有一个Visual Studio界面返回此信息?我找不到它.

Is there a Visual Studio interface that returns this information? I haven't been able to find it.

如果不可能，那么至少可以确定该扩展程序是否在实验性实例中运行，还是在非实验性实例中运行?我可以使用这些信息来找到扩展目录.

If that's not possible, is it at least possible to determine if the extension is running in the experimental instance vs. non-experimental? I could use that information to locate the extension directory.

推荐答案

也许看看 IInstalledExtension.InstallPath .您可以通过 IVsExtensionManager .

Maybe look at IInstalledExtension.InstallPath. You can get an IInstalledExtension via an IVsExtensionManager.

不幸的是，备注中的消息表明这不是正确的处理方式:

Unfortunately, the message in the remarks suggests this is not the right way to do things:

尽管此API支持扩展管理器基础结构，但我们建议您不要使用它，因为它可能会发生更改.

Although this API supports the Extension Manager infrastructure, we recommend that you do not use it because it is subject to change.

这是代码:

    static IVsExtensionManager GetExtensionManager()
    {
        return myPackage.GetService(System.typeof(IVsExtensionManager)) as IVsExtensionManager;
    }
    static IInstalledExtension GetExtension(string identifier)
    {
        return GetExtensionManager().GetInstalledExtension(identifier);
    }
    static string GetExtensionDirectory(string identifier)
    {
        return GetExtension(identifier).InstallPath;
    }

string identifier是您在扩展程序source.extension.vsixmanifest文件的"ID"字段中输入的内容.默认为软件包GUID.

The string identifier is whatever you put in the "ID" field of your extension's source.extension.vsixmanifest file. It defaults to the package GUID.
