Creation of XML in. NET (linqtoxml)

Linqtoxml comparison is flexible and convenient, it is based on functional programming
The specific use is as follows:
Referencing the assembly using System.Xml.Linq;

1. Create a XDocument and set the document header

XDocument XDoc = new XDocument ();
XDoc. Declaration = new Xdeclaration ("1,0", "gb2312", null);

2. Create the root node element XElement

XElement root = new XElement ("root");//Create Node

XDoc. Add (root);//adding child nodes

3. Create child nodes and add attributes

Similar to DOM schema creation

XElement stu= New XElement ("Student");//Create Student node

XAttribute id= New XAttribute ("id", "001");//create a property ID and set the value to "001"

Stu.add (ID);//Add id attribute for Stu node

Chained mode creation

XElement stu= New XElement ("Student", New XAttribute ("id", "001"));

4. Create a child node for student (three Methods of creation)

XElement name = new XElement ("name");

XText xt = new XText ("Zhang San");

　　Name. Add (XT);

XElement age = New XElement ("Age");

　　Age. Value = "12";

　　XElement gender = new XElement ("Gender", "male");

5. Save
XDoc. Save ("Xxx.xml");

Complete chained creation
New XDocument (New Xdeclaration ("1.0", "gb2312", null), New XElement ("root", New XElement ("Student", New XAttribute ("id", "001"), New XElement ("Name", "Zhang San"), New XElement ("Age", "page"), New XElement ("Gender", "Male"))). Save ("Xxx.xml");

Build Result:

<?xml version= "1.0" encoding= "gb2312"?>
<root>
<student id= "001" >
<Name> Zhang San </Name>
<Age>12</Age>
<Gender> Men </Gender>
</Student>
</root>
