使用configSource转换包含的配置文件 [英] Transforming included configuration files using configSource

问题描述

这个问题有点像是两个伙伴.在VS2015中，我的MVC项目具有多个不同的构建配置，包括测试，UAT，实时等.使用我的web.config，只需右键单击它，然后选择 Add Config Transform 即可为每个构建配置创建转换文件

This question is kind of a two parter. In VS2015 my MVC project has multiple different build configurations, Test, UAT, Live etc. With my web.config I can simply right click it and select Add Config Transform to create the transform files for each build configuration.

如果我有一个外部配置文件(例如Log4Net.config)，如何配置它以具有像web.config这样的相关转换?是通过编辑project.csproj文件手动完成的吗?

If I have an external config file, such as Log4Net.config how can I configure this to have dependant transforms like web.config ? Is this done manually by editing the project.csproj file ?

第二，因此我有一个web.config文件:

Secondly, I have a web.config file thus :

<configuration>
    <configSections>
        <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, Log4net" />
    </configSections>

    ...

    <log4net configSource="Log4Net.config" />
</configuration>

构建项目时，web.config会自动通过project.csproj文件中的以下AfterBuild目标进行转换:

When I build the project, the web.config automatically gets transformed through the following AfterBuild target in the project.csproj file :

<Target Name="AfterBuild">
    <TransformXml Source="Web.config"
            Transform="Web.$(Configuration).config"
            Destination="$(OutputPath)\$(AssemblyName).config" />
</Target>

如何使用相同的配置转换来转换包含的Log4Net.config文件?我意识到可以将另一个TransformXml放入AfterBuild目标中，但这是进行此转换的正确方法，还是我错过了什么?

How can I transform the included Log4Net.config file using the same configuration transformation ? I realise that I could place another TransformXml into the AfterBuild target, but is this the correct way of doing this transform, or am I missing something ?

推荐答案

我选择了使用基本Log4Net.config文件，用于每个构建配置的Log4Net.XXX.config文件以及在AfterBuild目标:

I opted for the solution of using a base Log4Net.config file, a Log4Net.XXX.config file for each build configuration and an additional TransformXml task in the AfterBuild target :

• Log4Net.config
• Log4Net.Debug.config
• Log4Net.Release.config
• Log4Net.Test.config
• Log4Net.UAT.config

project.csproj文件现在看起来像这样:

The project.csproj file now looks like this :

<Content Include="Log4Net.config">
  <CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>
<None Include="Log4Net.Debug.config">
  <DependentUpon>Log4Net.config</DependentUpon>
</None>
<None Include="Log4Net.Release.config">
  <DependentUpon>Log4Net.config</DependentUpon>
</None>
<None Include="Log4Net.Test.config">
  <DependentUpon>Log4Net.config</DependentUpon>
</None>
<None Include="Log4Net.UAT.config">
  <DependentUpon>Log4Net.config</DependentUpon>
</None>

....

<Target Name="AfterBuild">
   <TransformXml Source="Web.config" Transform="Web.$(Configuration).config" Destination="$(OutputPath)\$(AssemblyName).config" />
   <TransformXml Source="Log4Net.config" Transform="Log4Net.$(Configuration).config" Destination="$(OutputPath)\Log4Net.config" />
</Target>

一个示例Log4Net.Test.config看起来像这样(我正在使用转换来更改连接字符串和Log4Net的日志记录级别):

And an example Log4Net.Test.config looks like this (I am using the transform to change connection strings and Log4Net's logging level) :

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

<log4net  xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
    <appender>
        <connectionString
            value="Data Source=example.com;Initial Catalog=ExampleLogs;User ID=xxx;Password=xxx"
            xdt:Transform="Replace" />
    </appender>

    <root>
        <level
            value="DEBUG"
            xdt:Transform="Replace" />
    </root>
</log4net>

这将成功转换输出路径中的Log4Net.config文件.它使用与转换web.config文件相同的方法，因此，选择该项目的任何其他开发人员都应该易于理解.

This transforms the Log4Net.config file in the output path successfully. It uses the same approach as transforming web.config files and so should be easily understandable by any other developer that picks up the project.

尽管这可行并且已经投入生产了一段时间，但我仍在寻找一些确认，证明这是对包含的配置文件进行转换的正确方法.

Whilst this works and has been in production for a while now, I'm still looking for some confirmation that this is the correct way of doing transforms of included config files.
