如何解決反序列化xml文件時產生的問題？

Question

反序列化xml文件時發生以下問題

{System.InvalidOperationException: There is an error in XML document (3, 514). ---> System.NotSupportedException: XLinq
   at System.Xml.Serialization.XmlSerializationReader.ReadXmlNodes(Boolean elementCanBeType)
   at System.Xml.Serialization.XmlSerializationReader.ReadTypedPrimitive(XmlQualifiedName type, Boolean elementCanBeType)
   at System.Xml.Serialization.XmlSerializationReader.ReadTypedPrimitive(XmlQualifiedName type)

這是Xml，我正在嘗試解析，

並使用以下類對其進行反序列化，

幫我解決問題

Answer 1

問題在於Xml文件中的空節點值。 我已經將反序列化類的屬性修改為Nullable，它工作正常。

Answer 2

• http://www.w3.org/TR/2000/REC-xml-20001006#syntax指出，＆符號必須轉義為＆或類似符號。 所以沒關系。

• 顯然有問題。 也許是您的XML。 因此，刪除它的主要部分，找出導致錯誤的節點。

• 也許這是您的課程定義。 因此，請使用XDocument.Load或.Parse來確定XML是否正確，並知道您的類定義有錯誤。 通過從中刪除部分來簡化類，並找出哪個字段/屬性/屬性/引起錯誤。
