Thank you

Tried this but...I get and error :

XmlDocument doc = new XmlDocument();
          doc.Load(filename);
          XmlElement fileElement = doc.CreateElement("configuration");
          XmlElement rootElement = (XmlElement)doc.SelectSingleNode("/Root");
          rootElement.AppendChild(fileElement);

          doc.Save(filename);

推荐答案

根据我的理解，你不能在根元素之外使用XmlDocument在XML文件中添加任何东西，而且是< ;的ConnectionStrings取代。其他方法是使用文件处理。以下是样本

As per my understanding you can not add anything in XML file using XmlDocument outside the root element and which is <connectionStrings>. Other way to do that is to use File handling. Below is sample

string xml = File.ReadAllText(filename);
      xml = "<configuration>" + xml + "</configuration>";
      File.WriteAllText(filename, xml);
