无法将XmlReader加载到XDocument中

Question

我试图加载XmlReader到一个XDocument更容易操纵.XML格式正确且有效(我仔细检查过).当我尝试加载它时XDocument,我得到了一个InvalidOperationException

此操作后,XmlReader状态应为EndOfFile.

加载它的代码是

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

我已经包含了导致问题的XML示例.我可以顺利地序列化和反序列化这个类,但不加载它.有任何想法吗？

Answer 1

很晚才回答,以防有人遇到同样的问题.您可以通过ReadSubtree()在阅读器上使用来修复它,例如:

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

Answer 2

此错误意味着在读取器加载了它认为是 XML 文档的内容后，存在额外的数据。请验证您的 XML 文件在最终结束元素之后是否不包含任何数据，并且已XmlReader初始化为从根元素或文件开头读取，仅此而已。
