推荐答案

if (root.HasChildNodes)
{
  foreach (XmlNode node in root.ChildNodes)
  {
    //your code...

    if (Correct.Count > 0)
    {
      //your code...
      //don't save the document here....
      //doc.Save(FolderPath + "\\" + file.Name);
    }
    if (Wrong.Count > 0)
    {
      //your code...
      //don't save the document here....
      //doc.Save(FolderPath + "\\" + file.Name);
    }
    // save after all correcr and wrong child node added
    doc.Save(FolderPath + "\\" + file.Name);
  }

}
