c# - 无法将 XmlReader 加载到 XDocument 中

Question

我正在尝试将 XmlReader 加载到 XDocument 中以便于操作。 XML 格式正确且有效(我仔细检查过)。当我尝试将它加载到 XDocument 时，我得到一个 InvalidOperationException

The XmlReader state should be EndOfFile after this operation.

加载这个的代码是

public void ReadXml(System.Xml.XmlReader reader)
{
    var doc = XDocument.Load(reader);
}

我提供了导致问题的 XML 示例。我可以毫无问题地序列化和反序列化此类，但不能加载它。有什么想法吗？

很晚的回答，以防有人遇到同样的问题。您可以通过在阅读器上使用 ReadSubtree() 来修复它，例如:

public void ReadXml(System.Xml.XmlReader reader)
{
     var doc = XDocument.Load(reader.ReadSubtree());
}
