LINQ生成XML格式数据

代码如下

复制代码

using System.Xml.Linq;
static void Main(string[] args)
{
//LINQ生成XML格式的数据，相比较把对象序列化成XML文件要灵活性好点using System.Xml.Linq;
List list = new List
{
new Student{ID=1,Name="林书豪",Scores=new List{80,90,100}},
new Student{ID=1,Name="张三丰",Scores=new List{77,88,99}}
};

var xml = new XElement("Root",
from l in list
let x = String.Format("{0},{1},{2}", l.Scores[0], l.Scores[1], l.Scores[2])
select new XElement("Student",
new XElement("ID", l.ID),
new XElement("Name", l.Name),
new XElement("Scores", x)
)
);
Console.Write(xml);
Console.Read();

/*

1
林书豪
80,90,100

2
张三丰
877,88,99

*/
}

class Student
{
public int ID { get; set; }
public string Name { get; set; }
public List Scores;
}

序列化成XML文件

对象序列化成XML

代码如下

复制代码

using System.Xml.Serialization;
public void WriteXML()
{
Product[] productlist = new Product[] {
new Product(){Name="苹果",Price=5.5},
new Product(){Name="橘子",Price=2.5},
new Product(){Name="干柿子",Price=16.00}
};
XmlSerializer writer = new XmlSerializer(typeof(Product[]));

StreamWriter file = new StreamWriter(Server.MapPath("product.xml"));
writer.Serialize(file, productlist);
file.Close();
}

public class Product
{
public string Name { get; set; }
public double Price { get; set; }
}
生成一个XML文件：

<?xml version="1.0" encoding="utf-8"?>

苹果

5.5

橘子

2.5

干柿子
