C# XML 序列化和反序列化_c#xml序列化和反序列化-优快云博客

本文介绍了一种使用C#实现的XML序列化和反序列化方法，通过自定义对象与XML字符串之间的转换，实现了数据的有效存储和读取。文章详细展示了序列化过程中的关键步骤，包括创建XmlSerializer实例、使用MemoryStream进行数据流操作、以及通过StringBuilder收集XML字符串。同时，也介绍了如何从XML字符串中反序列化出原始对象。

调用实例

string XMLString = XmlUtility.SerializeToXml(_SocketXML_590Req);

XmlFactory590Req.message _SocketXML_590Req = XmlUtility.DeserializeToObject<XmlFactory590Req.message>(XMLString);
