.NET - 在App.Config

Question

我有一个.NET 4.7应用程序。在这个应用程序中，我有几个我想在App.config文件中使用的自定义配置元素。出于这个原因，我在我的项目中定义了几个与配置相关的类。这个项目编译，结构如下：

./
  /ConfigurationItems
    Children
    Child
  App.config
  Program.cs

在我的App.config文件中，我有以下内容：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="Children" type="MyOrg.MyApp.ConfigurationItems.Children, MyOrg.MyApp.exe" />
  </configSections>

  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7" />
  </startup>  

  <Children>
    <Child Name="Joe" />
    <Child Name="Suzy" />
  </Children>  
</configuration>

当我运行此应用程序时，我会转到以下行：

  var children = ConfigurationManager.GetSection("Children") as MyOrg.MyApp.ConfigurationItems.Children;

此时，我收到以下异常：

System.Configuration.ConfigurationErrorsException: 'An error occurred creating the configuration section handler for Children: Could not load file or assembly 'MyOrg.MyApp.exe' or one of its dependencies. The system cannot find the file specified.'

FileNotFoundException: Could not load file or assembly 'MyOrg.MyApp.exe' or one of its dependencies. The system cannot find the file specified.

我做错了什么？如何使用项目中定义的自定义配置元素？

谢谢

从type元素移除<section>属性中的“.exe”文件扩展名：

  <configSections>
    <section name="Children" type="MyOrg.MyApp.ConfigurationItems.Children, MyOrg.MyApp" />
  </configSections>
