C# 我可以序列化HtmlAgilityPack.HtmlDocument吗

代码：

---

基于异常声明该类未标记为可序列化的事实，我会说“否”。问题：为什么要在会话中存储

HtmlDocument

对象？为什么不将其存储为文本？

基于此异常，该类未标记为可序列化

序列化

HtmlDocument

的一种方法是创建一个模仿该类的类，将所有属性从一个复制到另一个，并序列化副本。或者，您可以下载源代码，编辑可序列化的

HtmlDocument

类，然后在项目中重新编译和引用该类

---

您可以使用诸如之类的类来来回映射属性，这样您就不会自己编写所有映射代码。

这是一大堆内容，没有任何解释。。。注意，你的问题可能会在代码和堆栈跟踪中得到回答。。。我不确定他们是否有其他沟通方式。@m.Babcock:

Console.WriteLine（“我不明白”）

HtmlAgilityPack

是开源的，所以这不是唯一的方法。
