如何在XML文件的特定部分中添加一个部分，c# ?

I have this XML file:

我有这个XML文件:

<a>
   <b>
   <name>Ion</name>
   </b>
   <c>
     <article>A10</article>
     <price>100</price>
   </c>
   //here I want to add a new section
   <f>....</f>
   </b>
</a>

I want to add section :

我想补充一节:

 <d>
     <info1>test</info1>
     <info2>test 2</info2>
 </d>

after section <c> ,between ''.

后段，中间"。

I wrote this code in c# to add define and add section d:

我用c#编写了这段代码来添加定义和添加d部分:

XDocument doc = XDocument.Load(file.Directory + "//" + file.Name);
XElement newElement = new XElement("d",
                                       new XElement("info1", txtInfo1.Text),
                                       new XElement("info2", txtInfo2.Text)
                    );
doc.Element("a").Add(newElement);

But with this code I add <d> section in <a> tag and I want to add after <c> section (<a><b><c>...</c><d>...<d/><f>...</f></b></a>)

但是这个代码我添加< d >在 <一> 标记部分,我想添加后< c >部分( <一> < b > < c >…< / c > < d > < d / > < f >…< / f > < / b > < / >)

3 个解决方案

#1

 string path = file.Directory + "//" + file.Name;
 XDocument doc = XDocument.Load(path);
 doc.Root.Element("b").Add(newElement); 
 doc.Save(path); // save document

UPDATE (adding between c and f):

更新(c和f之间增加):

 doc.Root.Element("b").Element("c").AddAfterSelf(newElement);

#2

Looks like you're adding it to the wrong tag. Based on your question you want it added to b:

看起来你把它加错标签了。根据你的问题，你想把它加到b中:

doc.Root.Element("b").Add(newElement);

#3

Instead of doc.Element("a").Add(newElement);

而不是doc.Element阀门(“a”)(newElement);

try this:

试试这个:

doc.Root.Element("b").Add(newElement);

#1

 string path = file.Directory + "//" + file.Name;
 XDocument doc = XDocument.Load(path);
 doc.Root.Element("b").Add(newElement); 
 doc.Save(path); // save document
