Question

我甚至不知道我是否可以做我正在尝试的事情，但我从几个项目中导入了表单并添加了对这些项目的引用。每个项目都有一组不同的连接字符串，我试图让它们在App.config中共存，我可以通过SECTION过滤（用户从组合框中选择连接）。我希望我可以通过实现ConfigSections来实现这一点。如果它可行，我显然不知道如何。

附件是我的App.config。我收到错误'配置系统无法初始化'，当我深入细节时，它说'无法识别的配置部分amSettings

我正在尝试做什么？如果是这样，我需要纠正什么？

Answer 1

将部分名称从amSettings.Properties.Settings更改为amSettings并将cbSettings.Properties.Settings更改为cbSettings

e.g。

    `<section name="amSettings" `

以下是一个全面的例子：

如果您将配置文件更改为：

    <configSections>
        <section name="amSettings"
                 type="System.Configuration.AppSettingsSection"
                 allowExeDefinition="MachineToLocalUser"
                 requirePermission="false"/>
        <section name="cbSettings"
     type="System.Configuration.AppSettingsSection"
     requirePermission="false"/>
  </configSections>
  <amSettings>
      <add key="ABC" value="DEF"/>
  </amSettings>

然后您可以使用以下代码访问密钥ABC：

        var config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
        AppSettingsSection appSettingSection = (AppSettingsSection)config.GetSection("amSettings");
        var a = appSettingSection.Settings["ABC"].Value;

解决方案是两件事。将部分名称更改为user469104推荐并将部分包装在组名称中。
