推荐答案

``node.RemoveAll（ ）``不会删除节点本身。

尝试下面这样的事情 -

``node.RemoveAll()`` will not delete the node itself.
Try something like following-

XmlDocument doc = new XmlDocument();
doc.Load(path);
XmlElement el = (XmlElement)doc.SelectSingleNode("/Announcements/Announce[ID=TextId]");		
if(el != null) 
{ 
  el.ParentNode.RemoveChild(el); 
}
UploadToSFTP.UploadFileToSFTPServer();//not sure what it does for you
doc.Save(path);		

希望，它有帮助：）

Hope, it helps :)

你必须从中删除你想要的节点父节点。

You have to remove the node you want from its parent node.

if (attribute.Value == TextId) {
   XmlNode parentNode = node.ParentNode;
   parentNode.RemoveChild(node);
}

希望这会有所帮助。

Hope this helps.
