DeSerializing an XML file to a C# class

Question

有谁知道通过使用XSD工具生成的类来探索反序列化的XML文件（而不是XPATH）有什么优点（内存/速度）？

Answer 1

我想说的好处是，您将获得一个更易于使用的强类型类，并且如果文件中的XML数据对于创建对象无效，则该类的构造函数也会引发异常，因此您将获得一个免费进行最少的数据验证。

Answer 2

如果您不想编写样板代码，并且在执行过程中需要检查XML的任何值，那么XSD.exe生成的类不会出错。

Answer 3

The two are very different; but XmlSerializer will always deserialize entire objects; with XPath you can pick and choose. I'd use XmlSerializer personally, though - harder to get wrong.

XPath, however, is a complex beast that depends on the back-end. For example, XmlDocument (mutable) will behave differently to XPathDocument (read-only, optimized for query).
