2.在 程序中引用以下命名空间:
using System;
using System.Linq;
using System.Xml.Linq;
using System.Linq;
using System.Xml.Linq;
3.读取方法如下:
main 函数入口
class Program
{
static void Main(string[] args)
{
XDocument doc = XDocument.Load("demo.xml");
var text = from t in doc.Descendants("conf") //定位到节点
.Where(w => w.Element("to").Value.Contains('@')) //若要筛选就用上这个语句
select new
{
to = t.Element("to").Value,
froms = t.Element("from").Value,
head = t.Element("heading").Value,
body = t.Element("body").Value,
title = t.Element("title").Attribute("name").Value //注意此处用到 attribute
};
foreach (var a in text)
{
Console.WriteLine(a.to);
Console.WriteLine(a.froms);
Console.WriteLine(a.head);
Console.WriteLine(a.body);
Console.WriteLine(a.title);
}
Console.ReadKey();
}
}
{
static void Main(string[] args)
{
XDocument doc = XDocument.Load("demo.xml");
var text = from t in doc.Descendants("conf") //定位到节点
.Where(w => w.Element("to").Value.Contains('@')) //若要筛选就用上这个语句
select new
{
to = t.Element("to").Value,
froms = t.Element("from").Value,
head = t.Element("heading").Value,
body = t.Element("body").Value,
title = t.Element("title").Attribute("name").Value //注意此处用到 attribute
};
foreach (var a in text)
{
Console.WriteLine(a.to);
Console.WriteLine(a.froms);
Console.WriteLine(a.head);
Console.WriteLine(a.body);
Console.WriteLine(a.title);
}
Console.ReadKey();
}
}
结果:
小结: Linq to Xml 确实是个好东西 ,它极大地方便了我们的编程。
