推荐答案

差不多。 ..

根据定义，子节点在没有父节点的情况下不能存在，因此您需要做的是将父节点的所有子节点移动到另一个父节点然后删除 - 现在为空 - 节点...

LINQ to XML有很多很酷的方法o轻松做到这一点...

其中一个是 AddBeforeSelf [ ^ ] ...

Almost...
A child node, by definition, can not exists without parent, so what you have to do is to move ALL child nodes of the parent to an other parent and then remove - the now empty - node...
LINQ to XML has a lot of cool methods to do such thing with ease...
One of them is AddBeforeSelf[^]...

XElement nodeToRemove = bla-bla-bla;

nodeToRemove.AddBeforeSelf(nodeToRemove.Elements());
nodeToRemove.Remove();
