多个AppSettings文件，是可能吗？ [英] Multiple AppSettings files, is it possible?

问题描述

我要创建3个AppSettings配置文件：

I want to create 3 AppSettings config files:

• Database.config


• config


• Global.config

然后在我的App.config中添加：

And after add in my App.config:

<appSettings file="Database.config" />
<appSettings file="Messages.config" />
<appSettings file="Global.config" />

但是当我试图访问一个键，在三个文件之一与 ConfigurationManager 出现以下错误：

But when i try to access a key that there is in one of three files with the ConfigurationManager i got the following error:

配置系统无法初始化。每个配置文件只能显示一次。

Configuration system failed to initialize. Sections must only appear once per config file.

我不能有多个AppSettings配置文件？

I cannot have more than one AppSettings config file?

推荐答案

您不能有多个应用设置，因为它是节的名称。您可以添加一个新的部分，但使用与appsettings相同的部分定义。例如

You can't have more than one appsettings because that's the name of a section. You can add a new section though that uses the same kind of section definition as appsettings. E.g.,

<configuration>
    <configSections>
        <section name="DatabaseConfig" type="System.Configuration.NameValueFileSectionHandler, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"/>
    </configSections>
    ....
    <DatabaseConfig>
       <add key="Whatever" value="stuff"/>
    </DatabaseConfig>
</configuration>
