提前感谢在哪里创建id、标题等节点？看起来您是在重用这些节点，而不是创建新节点，这就是它无法正常工作的原因 如果您正在重用一个子节点，它将从当前节点中将其删除，并将其插入新节点，这就是您看到空元素的原因
也在这里检查，基本上是相同的问题。在哪里创建id、标题等节点？看起来您是在重用这些节点，而不是创建新节点，这就是它无法正常工作的原因 如果您正在重用一个子节点，它将从当前节点中将其删除，并将其插入新节点，这就是您看到空元素的原因
也请检查这里，基本上是相同的问题。您是否考虑过使用System.XML.Serialization命名空间，它有一个XMLSerializer类，可以很好地完成这类工作？这里有一些MSDN文档--其中深入介绍了一些好的示例，这里有一个简短的描述，足以说明基本内容--您是否考虑过使用System.XML.Serialization名称空间，它有一个XMLSerializer类，可以很好地完成这类工作？这里有一些MSDN文档，其中有一些很好的例子，有一些很深入的说明，还有一个简短的说明，基本内容已经足够了-您还没有说您使用的是哪个版本的.NET。如果使用.NET3.5或更高版本，那么我建议使用LINQtoXML，特别是当您可以从查询中获取强类型数据时。例如：

public class Testing

var items = new[]

这也可能有帮助-这也可能有帮助-只是一个参考，但您不需要rdr.HasRows，因为它与rdr.Read（）是冗余的，rdr.Read（）只在找到并返回另一行时返回true。只是一个参考，但您不需要rdr.HasRows，因为它与rdr.Read（）是冗余的，rdr.Read（）只在找到并返回另一行时返回true。
