关于vb.net:Custom配置节处理程序找不到处理程序

Custom config section handler can't find handler

我正在用我的自定义处理程序abramain.myconfigHandler在app.config中创建配置。

错误：

无法从程序集"system.configuration，version=4.0.0.0，culture=neutral，publicKeyToken=b03f5f7f11d50a3a"加载类型"abramain.myconfigHandler.applicationListCollection"。

相关讨论

问题似乎出在您为自定义部分指定处理程序的行上的app.config中：

1	<section name="applicationList" type ="AbraMain.MyConfigHandler.ApplicationListCollection"/>

自定义处理程序类型的类型声明还需要包含可在其中找到它的程序集。否则，它将尝试在默认的System.Configuration程序集中找到它。这也是你所说的错误信息。

因此，您也可以通过包含程序集的名称来解决问题。我假设你们的集会叫以东十一〔二〕。然后您需要将该行更改为：

1	<section name="applicationList" type ="AbraMain.MyConfigHandler.ApplicationListCollection, AbraMain"/>

不过，您似乎还有第二个问题。对于配置部分，需要有一个实现ConfigurationSection的处理程序。

因此，需要添加一个新类来执行此操作：

然后指向你的app.config使用它：

1	<section name="applicationList" type ="AbraMain.MyConfigHandler.ApplicationList, AbraMain"/>
