自定义配置部分

我复制并粘贴了 MSDN 上的示例

我从

<section 
    name="pageAppearance" 
    type="Samples.AspNet.PageAppearanceSection" 
    allowLocation="true" 
    allowDefinition="Everywhere"
  />

到

<section
    name="pageAppearance"
    type="Samples.AspNet.PageAppearanceSection, Samples.AspNet " />

除此之外，所有代码都完全相同.出于某种原因，来自 msdn 的源代码仅显示默认值.谁能帮我弄清楚为什么它不会读取配置部分，谢谢.

other than that all the code is the exact same. For some reason the source code from msdn only displays the default value. Can someone help me figure out why it will not read the config section please, Thank you.
