問題描述

我有一個被許多其他 Web 應用程序項目引用的類庫.它的 app.config 中有許多我希望在所有引用 Web 項目中使用的設置.構建類庫時，它會將 app.config 作為 .dll.config 復制到自己的 bin 文件夾中.

I have a class library that is referenced by many other web application projects. It has many settings in its app.config that I wish to use in all of the referencing web projects. When the class library is built, it copies the app.config to its own bin folder as <assembly.name>.dll.config.

• 默認情況下，Visual Studio/MSBuild 似乎不這樣做.
• 更改 Copy to Output Directory 或 Build Action(任意組合)不起作用.
• SlowCheetah VS 擴展似乎可以做我想做的事情，這是其配置轉換過程的意外副作用，但我想這樣做 沒有任何第 3 方擴展.

• Visual Studio / MSBuild does not seem to do this by default.
• Changing Copy to Output Directory or Build Action (in any combination) does not work.
• SlowCheetah VS extension appears to do what I want as an unintended side-effect of its config transform process, but I want to do this without any 3rd-party extensions.

順便說一句:手動將所有這些配置放入每個 Web 應用程序項目中是不切實際的.我可以通過在 bin 文件夾中查找 <assembly.name>.dll.config 來讀取文件，然后從那里提取設置.我已經可以做到這一點，所以這不是問題 - 我只需要確保文件可以在那里閱讀

As an aside: It's impractical to manually put all of this config in each of the web application projects. I can read the file by looking for <assembly.name>.dll.config in the bin folder, and extract the settings from there. I can already do this, so that's not an issue - I just need to ensure the file is going to be there for reading

推薦答案

這可以通過將以下內容添加到類庫的項目文件 assembly.name.csproj 來實現，無需 3rd-party 工具:

This can be achieved without 3rd-party tools by adding the following to the class library's project file, assembly.name.csproj:

// Find this <Import> element for Microsoft.CSharp.targets
<Import Project="$(MSBuildToolsPath)Microsoft.CSharp.targets" />
// Add this <ItemGroup> element immediately after
<ItemGroup>
    <Content Include="app.config">
        <Link>$(TargetName).dll.config</Link>
        <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </Content>
</ItemGroup>

這會導致 app.config 被復制到將其作為 .dll.config 引用的任何項目.很好，因為你只需要配置一個.csproj文件，效果就級聯到所有引用的項目.

This causes the app.config to be copied to whichever project is referencing it as <assembly.name>.dll.config. It's good because you only need to configure the one .csproj file and the effect cascades out to all referencing projects.
