C# Xml根节点未关闭

我正在使用xmlwriter创建一个xml文档。xml文档如下所示：

<?xml version="1.0" encoding="utf-8" ?> 
<ExceptionsList /> 

string formatDate = DateTime.Now.ToString("d-MMM-yyyy");

XmlTextWriter xmlWriter = new XmlTextWriter(xmlfileName, Encoding.UTF8);

xmlWriter.Formatting = Formatting.Indented;
xmlWriter.Indentation = 3;
xmlWriter.WriteStartDocument();

xmlWriter.WriteStartElement("ExceptionsList"); // ExceptionsList (Root) Element

xmlWriter.WriteEndElement(); // End of ExceptionsList (Root) Element

xmlWriter.WriteEndDocument();

xmlWriter.Flush();
xmlWriter.Close();

XDocument xml = XDocument.Load(xmlFileName);
XElement root = xml.Root;

root.Add(new XElement("Exception",
    new XElement("Exception Type", exceptionType),
    new XElement("Exception Message", exceptionMessage),
        new XElement("InnerException", innerException),
    new XElement("Comment", comment)));

xml.Save(xmlFileName);

XDocument xml = new XDocument();
xml.Add(new XElement("Exception",
    new XElement("ExceptionType", "Exception"),
    new XElement("ExceptionMessage", 
        new XElement("InnerException", "innerException")),
    new XComment("some comment")));

xml.Save("sample2.xml");

我向根节点添加如下内容：

<?xml version="1.0" encoding="utf-8" ?> 
<ExceptionsList /> 

string formatDate = DateTime.Now.ToString("d-MMM-yyyy");

XmlTextWriter xmlWriter = new XmlTextWriter(xmlfileName, Encoding.UTF8);

xmlWriter.Formatting = Formatting.Indented;
xmlWriter.Indentation = 3;
xmlWriter.WriteStartDocument();

xmlWriter.WriteStartElement("ExceptionsList"); // ExceptionsList (Root) Element

xmlWriter.WriteEndElement(); // End of ExceptionsList (Root) Element

xmlWriter.WriteEndDocument();

xmlWriter.Flush();
xmlWriter.Close();

XDocument xml = XDocument.Load(xmlFileName);
XElement root = xml.Root;

root.Add(new XElement("Exception",
    new XElement("Exception Type", exceptionType),
    new XElement("Exception Message", exceptionMessage),
        new XElement("InnerException", innerException),
    new XElement("Comment", comment)));

xml.Save(xmlFileName);

XDocument xml = new XDocument();
xml.Add(new XElement("Exception",
    new XElement("ExceptionType", "Exception"),
    new XElement("ExceptionMessage", 
        new XElement("InnerException", "innerException")),
    new XComment("some comment")));

xml.Save("sample2.xml");

这也给了我一个运行时堆栈溢出错误

任何帮助都将不胜感激

提前谢谢

您的代码是正确的，您不需要更改

异常列表

元素的关闭方式

xmlWriter.WriteStartElement("ExceptionsList"); // ExceptionsList (Root) Element

xmlWriter.WriteStartElement("Exception"); // An Exception element
xmlWriter.WriteEndElement();

xmlWriter.WriteEndElement(); // End of ExceptionsList (Root) Element

在第二个代码片段中，您需要从元素名称中删除这些空格，因为XML规范禁止这样做，并将元素添加到

XDocument

实例中，如下所示：

<?xml version="1.0" encoding="utf-8" ?> 
<ExceptionsList /> 

string formatDate = DateTime.Now.ToString("d-MMM-yyyy");

XmlTextWriter xmlWriter = new XmlTextWriter(xmlfileName, Encoding.UTF8);

xmlWriter.Formatting = Formatting.Indented;
xmlWriter.Indentation = 3;
xmlWriter.WriteStartDocument();

xmlWriter.WriteStartElement("ExceptionsList"); // ExceptionsList (Root) Element

xmlWriter.WriteEndElement(); // End of ExceptionsList (Root) Element

xmlWriter.WriteEndDocument();

xmlWriter.Flush();
xmlWriter.Close();

XDocument xml = XDocument.Load(xmlFileName);
XElement root = xml.Root;

root.Add(new XElement("Exception",
    new XElement("Exception Type", exceptionType),
    new XElement("Exception Message", exceptionMessage),
        new XElement("InnerException", innerException),
    new XElement("Comment", comment)));

xml.Save(xmlFileName);

XDocument xml = new XDocument();
xml.Add(new XElement("Exception",
    new XElement("ExceptionType", "Exception"),
    new XElement("ExceptionMessage", 
        new XElement("InnerException", "innerException")),
    new XComment("some comment")));

xml.Save("sample2.xml");

我认为问题在于：

    new XElement("Exception Type", exceptionType),
     new XElement("Exception Message", exceptionMessage),

Exception-Type

和

Exception-Mesage

都不是xml元素的有效名称。当然，如果您使用这个（注定的）方法来记录错误。。。堆栈溢出。

我很困惑。。。你为什么说它没有适当地关闭？我觉得这很接近…真的不明白你的意思。堆栈溢出发生在哪里？为什么不希望关闭根元素？为什么希望XmlWriter产生无效的输出？是什么阻止了您将第二个代码片段（或合适的调用）放在ExceptionList的开始和结束元素调用之间？是的，这就是导致stackoverflow的原因。我知道了。TBH，我从未在xml标记中使用空格。我不知道这次为什么这么做：哦，谢谢你的评论！
