C＃中，我们可以分享的App.config项目之间的一些内容是什么？我们可以、项目、内容、config
我在Visual Studio 2008中的解决方案两个独立的项目。两者都有自己的App.config。但是，在一个项目中，我需要在另一个项目的App.config中定义的一个或两个属性。是否有可能分享来自其他项目的App.config部分内容？
I have two independent projects in my Visual Studio 2008 solution. Both has its own App.config. But in one project, I need one or two properties defined in another project's App.config. Is it possible to share part of the App.config contents from other project?
推荐答案
是 - 当然。任何配置部分可外部化 - 例如：
Yes - of course. Any configuration section can be "externalized" - e.g.:
<appSettings configSource="AppSettings.DEV.config" />
<connectionStrings configSource="MyConnection.config" />
或
<system.net>
<mailSettings>
<smtp configSource="smtp.TEST.config" />
VS。
<system.net>
<mailSettings>
<smtp configSource="smtp.PROD.config" />
任何配置部分可以被放入一个单独的文件，可以在项目之间共享 - 但没有配置节的集团，不幸的是，它有时有点棘手知道哪个是哪个。
Any configuration section can be put into a separate file that can be shared between projects - but no configuration section groups, and unfortunately, it's sometimes a bit tricky to know which is which.
另外，在某些情况下，Visual Studio会抱怨（用红色波浪下划线）认为，configSource理应是无效的 - 但它是 - 它的配置节对象中的.NET配置系统。
Also, in some cases, Visual Studio will complain (using red wavy underlines) that the "configSource" supposedly isn't valid - but it is - it's defined on the ConfigurationSection object in the .NET config system.
更新： 另一个特点，几乎没有足够的开发者似乎知道和使用是在Visual Studio中，从不同的项目的添加现有文件为纽带的能力
UPDATE: another feature that hardly enough developers seem to know and use is the ability in Visual Studio to add existing files from a different project as a link:
通过这个，你可以添加链接到文件到您的本地项目，他们会始终保持最新。伟大的工作效率助推器，如果你需要做一些文件级共享（如常见的配置文件，或者这样的）！
With this, you can add links to files into your local project, and they'll always be kept up to date. Great productivity booster if you need to do some file-level sharing (like for common configuration files or such)!
