带有单独的.config文件的System.Configuration

http://msdn.microsoft.com/en-us/library/2tw134k3.aspx

我想知道的是(我今天在网上到处寻找)。。。

<configuration>
  <configSections>
    <sectionGroup name="pageAppearanceGroup">
      <section
        name="pageAppearance"
        type="HelperAssembly.Configuration.PageAppearanceSection,HelperAssembly"
        allowLocation="true"
        allowDefinition="Everywhere"
      />
    </sectionGroup>
  </configSections>


  <pageAppearanceGroup fileName="SomeSeparateFile.config"/>

</configuration>

..................

当然,上面的方法是行不通的。

下面是我对上面提到的微软文章的复制/粘贴。 当我把它贴在这里的时候,它已经完全发挥作用了。
