C# &引用；无法加载类型“；从app.config

我继承了一个功能正常的程序，目前它作为一项服务工作。该服务所做的只是在另一个类中调用一个方法，所以我正在尝试编写一个可以运行的winform项目，以便能够处理itit。我已经复制并粘贴了app.config文件，并将项目名称改为servicetester，改为一个新的非服务项目。我还从服务和it构建中复制了不同的代码位和其他代码。当我尝试使用该行运行项目时，我收到以下消息

var connectionManagerDataSection = ConfigurationManager.GetSection("CustomConfigurationSection") as clsCustomConfigurationSection;

信息

An error occurred creating the configuration section handler for CustomConfigurationSection: Could not load type 'servicetester.Configuration.CustomConfigurationSect
ion' from assembly 'servicetester'. (D:\\thepath\\servicetester\\bin\\Debug\\servicetester.vshost.exe.Config line 4)"

内部异常

"System.TypeLoadException: Could not load type 'servicetester.Configuration.CustomConfigurationSection' from assembly 'servicetester'.
   at System.Configuration.TypeUtil.GetTypeWithReflectionPermission(IInternalConfigHost host, String typeString, Boolean throwOnError)
   at System.Configuration.RuntimeConfigurationRecord.RuntimeConfigurationFactory.Init(RuntimeConfigurationRecord configRecord, FactoryRecord factoryRecord)
   at System.Configuration.RuntimeConfigurationRecord.RuntimeConfigurationFactory.InitWithRestrictedPermissions(RuntimeConfigurationRecord configRecord, FactoryRecord factoryRecord)
   at System.Configuration.RuntimeConfigurationRecord.CreateSectionFactory(FactoryRecord factoryRecord)
   at System.Configuration.BaseConfigurationRecord.FindAndEnsureFactoryRecord(String configKey, Boolean& isRootDeclaredHere)

这是app.config，除了项目名称外，它与原始服务项目相同

<?xml version="1.0" encoding="utf-8" ?>
    <configuration>
      <configSections>
      <section name="CustomConfigurationSection" type="servicetester.Configuration.CustomConfigurationSection, servicetester" />
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
          <section name="Proj.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
        </sectionGroup>
  </configSections>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
  </startup>
  <CustomConfigurationSection>
    <EwsConfiguration username="a@b.com" password="letmein" version="2" emailStoreLocation="\\serverpath\" url="https://emailplace" subscriptionConnectionLifetime="15" debug="true"/>
  </CustomConfigurationSection>
  <applicationSettings>
    <Proj.Properties.Settings>
      <setting name="Proj_Email_Log" serializeAs="String">
        <value>http://path</value>
      </setting>
    </Proj.Properties.Settings>
  </applicationSettings>
</configuration>

http://path

没有通往成功的道路 C:\Users\MYUSERNAME\AppData\Local\MYCOMPANY\MYAPP.exe\u Url\u longnastyhash9982749827349879\1.0.0.0\user.config 或者我读过的任何其他类似的地方尝试删除

我已经清理并重建了一切

就.NET framework而言，winform应用程序与该服务的版本相同 这些是谷歌所说的最常见的事情。还有其他想法吗？

谢谢

您需要分区组和自定义分区的名称

var confSection = (CustomSection)System.Configuration.ConfigurationManager.GetSection("MCustomConfigurationSection/applicationSettings");

这里有一个配置示例，其中包含示例customAppSetting和sectionGroup

App.Config

    <?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>
    <sectionGroup name="CustomConfigurationSection">
      <section name="customAppSettings" type="System.Configuration.AppSettingsSection, System.Configuration, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
    </sectionGroup>
  </configSections>
  <customAppSettingsGroup>
    <customAppSettings>
      <add key="Key1" value="val1"/>
      <add key="Key2" value="val2"/>
    </customAppSettings>
  </customAppSettingsGroup>
</configuration>

无论Configuration.CustomConfigurationSection位于何处，servicetester项目都无法访问它。您可能缺少一个include，或者您可能需要将该类复制到servicetester项目。我已经复制了该类以及（希望）所有必需的类。您找到解决方案了吗？我也遇到了同样的问题。我删除了这个项目，添加了一个新项目，从头开始构建一切，忽略了现有的代码。新测试项目中的代码与旧测试项目中的代码完全相同，但仍然有效。我想这可能与项目文件/设置/属性有关，我想我两次都选择了相同的选项，但我不知道。我还创建了一个控制台项目，它第一次工作。也许试一下。试一下，但它会返回与我显示的相同的错误消息Use custom section，这将是有效的。还可以尝试编辑appconfig。

var section = ConfigurationManager.GetSection("CustomConfigurationSection/customAppSettings") as NameValueCollection;
var val1 = section["Key1"];
var val2 = section["Key2"];
