c# - 如何从 app.config 中读取自定义对象列表

Question

我在 app.config 中定义了自定义设置，但在阅读该部分时出现错误。它使用简单的结构，比如只读取一个配置文件，但一旦我有一个配置文件列表，它就会失败并出现错误:“未知元素“配置文件””。谁能告诉我我做错了什么？

这是我的 app.config 的一部分:

<?xml version="1.0"?>
<configuration>
  <configSections>
   <section name="DTester.Properties.ProfileSection" type="DTester.Settings.ProfileSection, DTester"/>
  </configSections>

    <DTester.Properties.ProfileSection>
        <profiles>
            <profile site="test1" urlscheme="http" urldomain="localhost">
                <dataSource dataSource="test2" databaseName="test1" dbUserName="test1" dbUserPassword="test1" />
                <user userName="test" password="test" TOHSoftwareVersion="8" iOSVersion="3" deviceUDID="12312"/>
            </profile>

            <profile site="test2" urlscheme="http" urldomain="localhost" >
                <dataSource dataSource="test2" databaseName="test2" dbUserName="test2" dbUserPassword="test2" />
                <user userName="test" password="test" TOHSoftwareVersion="3" iOSVersion="8" deviceUDID="123122"/>
            </profile>
        </profiles>
    </DTester.Properties.ProfileSection>

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

我用这个工具得到了响应 https://nconfiggen.codeplex.com/wikipage?title=Example2&referringTitle=Home

这是修改后的配置部分:

<DTesterConfiguration>
            <option cmpResWithOacis="true" valRecentRosterPat="false"  maxPatCount="1" maxResCount="3" maxDetCount="3" />
            <profiles defaultProfile="test1">
                <profile site="test1" urlscheme="http" urldomain="localhost">
                    <dataSource dataSource="test2" databaseName="test1" dbUserName="test1" dbUserPassword="test1" />
                    <user userName="test" password="test" TOHSoftwareVersion="dfdf" iOSVersion="dfdf" deviceUDID="dfdf"/>
                </profile>

                <profile site="test2" urlscheme="http" urldomain="localhost" >
