You can also set the app.configto read another file. Something like this:
您还可以设置app.config读取另一个文件。像这样的东西：
<?xml version="1.0"?>
<configuration>
<appSettings file="my\custom\file\path\external.config"/>
</configuration>

并且external.config将有 appSettings 部分：

<add key="myKey" value="myValue" />
</appSettings>
