配置错误异常答案

【问题标题】：ConfigurationErrorsException配置错误异常
【发布时间】：2019-02-02 21:09:27
【问题描述】：

我遇到了一个异常，我不知道如何调试。它被抛出在以下行：

        var serializer = new XmlSerializer(typeof(Universe));

System.Configuration.ConfigurationErrorsException 已被抛出初始化配置系统时出错。

什么是配置系统，它在哪里初始化，它与 XmlSerializer 有什么关系？

完整的例外：

【问题讨论】：

我认为异常的来源是你的代码的另一部分，比如 web.config
可能重复：stackoverflow.com/questions/443235/…
看起来您的代码正在序列化 xml 并在保存时出错。这可能是由于 xml 格式错误或 xml 包含非法 xml 字符。我会在 SaveLoader.cs 中放置一个断点并获取字符串 xml，然后将字符串放入在线 xml 验证程序中以查找错误。您可以使用菜单在 VS 中验证 xml：项目：添加新项目：XML。然后将 xml 字符串粘贴到视图中。错误会像编译器错误一样显示在错误列表中。
错误发生在任何实际序列化之前。我传入的只是类类型，我正在尝试编写它，而不是阅读它。此时没有 XML 文件。
问题似乎与应用程序配置有关。我不确定如何正确定义它们，尤其是因为我根本不想使用它们。我在 dev 构建的 monobundle 中找到了一个配置文件，但它是自动生成的。我尝试了各种建议的解决方案，但似乎没有任何解决方法，并且错误消息似乎保持不变。

【解决方案1】：

您在 app.config 文件中有错误。 runtime 部分存在问题。确保它已在其中声明并具有有效的结构和值。

这里的内部异常消息给出了提示

System.Configuration.ConfigurationErrorsException: Unrecognized configuration section <runtime>
