在MSBuild任务中读取配置值 [英] Read Config Value in MSBuild Task

问题描述

有没有办法在MSBuild任务中读取System.Config连接字符串？

Is there a way to read a System.Config connection string in an MSBuild task?

基本上我在配置文件中设置了连接字符串

Basically I have my connection string setup in a config file

<add name="MyApp.MyConnectionString" connectionString="..." />

我想在MSBuild任务中引用它...

And I would like to reference it in an MSBuild task like so ...

<Target Name="Migrate" DependsOnTargets="Build">
    ...
    <Migrate Connectionstring="$(MyApp.MyConnectionString)" ... />
</Target>

推荐答案

MSBuild社区任务项目，使用xpath提取值。

There's an XMLRead task in the MSBuild Community Tasks Project, that uses xpath to pull out a value.

<XmlRead 
  XPath="/add/@connectionString"
  XmlFileName="app.config">
    <Output TaskParameter="Value" PropertyName="MyConnectionString" />
</XmlRead>
<Message Text="MyConnectionString: $(MyConnectionString)"/>

（注意：完全未经测试）
