在Visual Studio中链接其他文件 [英] Link Additional Files in Visual Studio

问题描述

我试图在我的Visual Studio 2017的C＃项目中包含stylecop.json。我想出了如何通过在任何文本编辑器中修改.csproj来做到这一点的方法。

I am trying to include stylecop.json in my C# project on Visual Studio 2017. I have figured out how to do this by modifying the .csproj in any text editor:

<AdditionalFiles Include="stylecop.json">
      <Link>stylecop.json</Link>
</AdditionalFiles>

我想知道是否存在一种无需进行任何文本编辑的方法。我知道我总是可以像添加其他文件一样添加它，但是那样可以在项目文件夹中复制该文件，而不必在外部进行链接。

I am wondering if there is a way to do this without making any text edits. I understand I can always add it like any other files but that would make a copy of the file within project folder and not link it externally.

推荐答案

您可以在解决方案目录中的某个位置添加一个 Directory.Build.targets 文件（将应用于该目录或该目录下的所有项目），其内容如下：

You can add a Directory.Build.targets file somewhere in your solution directory (will apply to all projects at or below that directory) with the following contents:

<Project>
  <ItemGroup>
    <AdditionalFiles Update="@(AdditionalFiles)">
      <Link Condition="'%(Link)' == ''">%(Identity)</Link>
   </AdditionalFiles>
  </ItemGroup>
</Project>

请注意，在此处使用％（Identity）对于项目锥之外的项目不是最佳选择-例如当您拥有< AdditionalFiles Include = .. \..\foo.bar /> 时。为此，您可以使用类似于VS中基于SDK的项目的机制2017 15.3 / .net core 2.0工具：

Note that using %(Identity) here isn't optimal for items outside the "project cone" - e.g. when you have <AdditionalFiles Include="..\..\foo.bar" />. For this you can use a mechanism similar to what SDK-based projects will do in VS 2017 15.3 / .net core 2.0 tooling:

<Project>
  <ItemGroup>
    <AdditionalFiles Update="@(AdditionalFiles)">
      <LinkBase Condition="'%(LinkBase)' != ''">$([MSBuild]::EnsureTrailingSlash(%(LinkBase)))</LinkBase>
      <Link Condition="'%(Link)' == '' And !$([MSBuild]::ValueOrDefault('%(FullPath)', '').StartsWith($([MSBuild]::EnsureTrailingSlash($(MSBuildProjectDirectory)))))">%(LinkBase)%(RecursiveDir)%(Filename)%(Extension)</Link>
   </AdditionalFiles>
  </ItemGroup>
</Project>

这甚至会保留与例如匹配的项目的目录层次结构 .. \shared\ ** \ * .json 和目标文件夹可以使用 LinkBase 进行设置元数据：

This will even preserve directory hierarchies of items matched with e.g. ..\shared\**\*.json and the target folder could be set using the LinkBase metadata:

<AdditionalFiles Include="..\shared\**\*">
  <LinkBase>SharedFiles</LinkBase>
</AdditionalFiles>

请注意，对<$ c $进行更改后，您可能需要关闭并重新打开解决方案c> Directory.Build.targets 。在即将到来的VS 2017 15.3更新中，VS将自动监视更改。在以前的版本中，文件将由VS缓存，直到解决方案关闭。

Note that you may need to close and re-open the solution after making changes to Directory.Build.targets. In the upcoming VS 2017 15.3 update, changes will be monitored by VS automatically. In previous versions, the file will be cached by VS until the solution is closed.
