第一次机会 System.Configuration.ConfigurationErrorsException“此元素当前不与任何上下文关联”

Question

有谁知道这个特殊异常的含义以及如何解决它？

请注意，我并不是在“例外”对话框中寻求有关抑制它的帮助。 我想了解其根本原因以及如何解决该原因本身（如果可能的话）。

谢谢。

PS

导致FCE的行是：

using (ServiceHost host = new ServiceHost(typeof(WcfPortal)))

升级到.NET 4和VS2010后，问题不会自行产生。 我想微软已经修复了它。

Answer 1

在遇到完全相同的问题后，我浪费了大约一个小时。

我有一个 WPF 应用程序，它已成功调用 Web 服务并获取一些数据。

但是...今天早上，我进入VS2008中的“异常”对话框，并要求它抛出“公共语言运行时异常”的异常。

从那时起，我的应用程序一旦到达初始化 webservice 变量的位置就会崩溃：

MikesWebServiceSoapClient client = new MikesWebServiceSoapClient ();

A first opportunity exception of type 'System.Configuration. System.Configuration.dll 中发生 ConfigurationErrorsException'
附加信息：此元素当前不与任何上下文关联

我确实阅读了此 StackOverflow 线程中的注释，但感到困惑。 在“异常”对话框中，我可以禁用“System.Configuration”异常的抛出...但此异常仍然会发生。 而且我没有任何其他与 System.Configuration 相关的可以取消勾选的异常。

我什至尝试勾选“公共语言运行时异常”，但取消勾选它的每一个子项。 但我的应用程序仍然会因异常而崩溃...

最终，我意识到在“异常”对话框中，我需要添加一个名为“System.Configuration.ConfigurationErrorsException”的新异常类型”，单击“确定”，然后取消勾选这个新的异常类型。

现在，我的应用程序将运行，异常会默默发生，但应用程序将继续运行。

我确实喜欢 WPF，但可笑的是，我浪费了多少时间来追寻此类已经存在多年的愚蠢问题。

我不介意，但这是 VS2008 创建的 WebService 变量......而且它总是工作得很好。 直到你要求WPF关注异常，那就是......

Silverlight Web 服务。

如上所述，经过多次实验，我找到了解决此错误的有效方法——将所有内容从“调试”更改为“发布”。 这意味着更改 web.config 文件中的所有属性，例如 (from ="true")，以及将 Visual Studio 的配置管理器从“调试”设置为“发布”。

当你这样做时，错误就会消失。 我原来的解决方法是错误的——不需要像我建议的那样从数据集更改为类。 一旦更改为发布，错误就会消失。

Answer 3

我过去在处理 WCF 时也遇到过类似的问题。 在这种情况下，基本上是 MS 代码吞噬了异常，但在调试模式下它仍然被捕获为 FCE。 请参阅此链接 了解更多信息。

如果您的问题出在 WCF 中，则适当的解决方法是抑制 FCE 对话框，因为您对此无能为力。 如果它与 WCF 无关，我怀疑它可能位于您正在使用的另一个基类库或第三方 dll 中。 不管怎样，你对此无能为力。 根据我的经验，我从未见过这种异常会导致任何有意义的事情。

如果您认为它可能有一定价值，您可能需要发布更多有关异常起源的上下文信息，以便人们可以插话并提供帮助。

Answer 4

就我而言，以下解决方案有效：

1. 我找到了我的程序使用的配置（设置）文件（在异常详细信息中）。
2. 我停止了调试。
3. 我发现，我从该位置删除了配置文件。
4. 我重新编译了我的应用程序。

希望也适用于您的情况:)
