我想使用代码和LINQ-to-XML从头开始创建它.在加载事件"表单中，我编写了以下代码:

推荐答案

搜索要添加的元素并使用Add方法如下图

Search element you want to add and use Add method as shown below

xDoc.Element("content")
    .Elements("item")
    .Where(item => item.Attribute("id").Value == "2").FirstOrDefault()
    .AddAfterSelf(new XElement("item", "C", new XAttribute("id", "3")));

或

<Microsoft>
<DOTNet>

</DOTNet>
</Microsoft>


private void addToXml()
{
   XDocument xmlDoc = XDocument.Load("yourfile.xml");

  xmlDoc.Element("Microsoft").Add(new XElement("DOTNet", new XElement("Name", "Nisar"),
      new XElement("Forum", "dotnetobject"), new XElement("Position", "Member")));
    xmlDoc.Save("yourfile.xml");
  readXml();
}

<Microsoft>
<DOTNet>
  <Name>Nisar</Name>
  <Forum>dotnetobject</Forum>
  <Position>Member</Position>
</DOTNet>
</Microsoft>
