嗨，我有一个 XML 字符串，我希望使用 C# 在特定位置插入另一个 XML 块。

<测试><组></group><组></group></Test><lol><group></group></Lol>

我想在 <Test> 中的最后一个 < /group> 之后插入一个字符串，使它看起来像

<test><group></group><group></group><我加了这个组></i加了这个组></Test><lol><group></group></lol>

如果有人知道如何做到这一点，请告诉我。

提前致谢。

编辑：

该字符串不仅包含单个元素，还可能包含数百个元素和子元素和子子元素以及许多不同的属性。elementception 这是一个示例字符串，类似于 addme 的外观：

你可以这样做，首先将字符串加载为 xml

   string xmlContent = "Your xml string content";
   //parse the string as xml
   XDocument xmlDoc = XDocument.Parse(xmlContent);
   //get the element which matches your need.
   XElement areaElement = 
       (from el in xmlDoc.Descendants("area") where el.Attribute("id").Value=="workplace"
       select el).FirstOrDefault();
   //create a new group element
   XElement newGroup = new XElement("i added this group");
   //add a value for this element or add attributes what ever is needed to this group here
   //add the new group this will by default add it at the end of all other child elements.
   areaElement.Add(newGroup);
