ConfigurationErrorsException

Question

我得到一个例外，我不知道如何调试。它出现在以下行：

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

抛出System.Configuration.ConfigurationErrorsException错误初始化配置系统。

什么是配置系统，它在哪里被初始化以及它与XmlSerializer有什么关系？

完整的例外情况：

Answer 1

app.config文件中有错误。部分运行时存在问题。确保它已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>
