Question

我将Web应用程序/解决方案从.NET 3.5升级到4.5.2。并且在将XML反序列化为对象时遇到了问题（没有编译问题）。自.Net 2.0以来，该应用程序的先前版本在过去的12年中没有遇到任何问题。在运行时，CallStack显示以下错误。经过广泛的谷歌搜索后，似乎我必须添加Add（），但我无法弄清楚它在升级到.NET 4.5.2之后的容量和位置以及为什么停止工作。向Map和/或MapEntry添加空Add（对象obj）并不是一个技巧。我花了很多时间，感谢任何帮助！

[InvalidOperationException]：要进行XML可序列化，从IEnumerable继承的类型必须在其继承层次结构的所有级别都具有Add（System.Object）的实现。 System.Xml.XPath.XPathNodeIterator未实现Add（System.Object）。 [InvalidOperationException]：反映字段mapItems时出错 [InvalidOperationException]：存在反映类型Framework.Common.Configuration.StructuredSettings.Map的错误 [InvalidOperationException]：反映类型Framework.Reporting.ReportConfig
