读XML
XmlDocument xd = new XmlDocument();
string fileName = @"D:\test.xml";
xd.Load(fileName);
XmlNodeList xmlNoteList = xd.GetElementsByTagName("user");
List< User > users = new List< User >();
foreach (XmlElement item in xmlNoteList)
{
User user = new User();
user.Id = int.Parse(item.GetAttribute("id"));
XmlNodeList xnl = item.ChildNodes;
user.Name = xnl[0].InnerXml;
user.Age =int.Parse(xnl[1].InnerXml);
user.Gender = xnl[2].InnerXml;
users.Add(user);
}
foreach (var item in users)
{
Console.WriteLine(item);
}
Read XML
<? xml version = "1.0" encoding = "gb2312" ?>
< users >
< user id = '1' >
< name >张三</ name >
< age >15</ age >
< gender >男</ gender >
</ user >
< user id = '2' >
< name >李四</ name >
< age >14</ age >
< gender >男</ gender >
</ user >
</ users >
test.xml
写XML
string fileName =@"D:\test.xml";
XmlDocument xmlDoc = new XmlDocument();
XmlNode header = xmlDoc.CreateXmlDeclaration("1.0","utf-8",null);
xmlDoc.AppendChild(header);
//创建一级节点
XmlElement rootNode = xmlDoc.CreateElement("users");
List< User > list = GetUsers();
foreach (var item in list)
{
XmlElement xn = InserUser(item,xmlDoc);
rootNode.AppendChild(xn);
}
xmlDoc.AppendChild(rootNode);
xmlDoc.Save(fileName);
}
/// < summary >
/// 创建整个user的元素
/// </ summary >
/// < param name = "user" ></ param >
/// < param name = "xmlDoc" ></ param >
/// < returns ></ returns >
private static XmlElement InserUser(User user, XmlDocument xmlDoc)
{
XmlElement xn = xmlDoc.CreateElement("user");
xn.SetAttribute("id", user.Id + "");
xn.AppendChild(GetXmlNode(xmlDoc,"name",user.Name));
xn.AppendChild(GetXmlNode(xmlDoc, "age", user.Age + ""));
xn.AppendChild(GetXmlNode(xmlDoc, "gender", user.Gender));
return xn;
}
private static XmlElement GetXmlNode(XmlDocument xmlDoc,string name,string value)
{
XmlElement xn = xmlDoc.CreateElement(name);
xn.InnerText = value;
return xn;
}
private static List< User > GetUsers()
{
List< User > list = new List< User >();
for (int i = 0; i < 10; i++)
{
User user = new User();
user.Id = i;
user.Name = "Name" + i;
user.Age = 15;
user.Gender = "男";
list.Add(user);
}
return list;
}
Write XML
实体类
class User
{
public int Id { set ; get ; }
public string Name { get ; set ; }
public int Age { get ; set ; }
public string Gender { set ; get ; }
public override string ToString()
{
return Id + "," +Name + "," +Age+ "," + Gender;
}
}
