删除节点Linq到xml不起作用？！ [英] Remove a node Linq to xml is not working?!

问题描述

我正在尝试删除节点。当我执行messagebox.show（）时，它显示已找到该节点但文件中没有删除任何内容。我不确定我做错了什么。

Hi,
I am trying to remove a node. When I do a messagebox.show() it shows the node has been found but nothing is deleted in the file. I am not sure what I am doing wrong.

private static void RemoveElements()
        {
            XDocument doc = XDocument.Load("File.xml");

            var Result = (from c in doc.Descendants("Book")
                          where c.Attribute("ID").Value == "556544"
                          select c).First();
            MessageBox.Show(Result.ToString());
            Result.Remove();
        }

推荐答案

删除节点后，使用save方法将文档保存回磁盘。以下是示例代码（我根据我的示例xml文件修改了代码）。

Once you remove the node, save the document back to disk using the save method. Following is the sample code (I have modified your code as per my sample xml file).

XDocument doc = XDocument.Load("Books.xml");

var Result = (from c in doc.Descendants("book")
              where c.Attribute("id").Value == "111"
              select c).First();
Console.WriteLine(Result.ToString());
Result.Remove();
doc.Save("books1.xml");

这对我来说非常合适。
