将XML节点读取为c#对象
本文关键字：对象 读取 XML 节点 | 更新日期: 2023-09-27 18:13:38
我有一个xml文件。我想要读取它，之后我想要将该xml文件的值设置为我创建的对象，最后我想将这些对象添加到列表中。问题是，当我打印一些对象值时，添加列表后，所有主题都是相同的，属于最后一个<current id="3">节点。下面是xml文件和实现
<currents>
<current id="1">
<currentCode>1</currentCode>

您不必手动阅读文档。你可以使用XmlSerializer
1)复制xml文档到剪贴板(文档的内容)
2)使用VisualStudio中的PasteSpecial函数。编辑->粘贴特殊->粘贴XML AS类
或者用这些类

[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
