问题描述

文件xml：



< Music>

< song>

< songalbum> Fearless< / songalbum>

< songid> 1< / songid> 



< songname> Love Story< / songname>

< songlinks> / Album / Fearless / Taylor Swift - Taylor Swift _专辑320 lossless.mp3< / songlinks>

< / song>

< / Music>



code xaml



var xmlelem = XElement.Load（@" XMLlistmusic.xml"）;

var song = from x in xmlelem.Descendants（" song"）

// orderby prod.Element（" songname"）。Value

选择p.Element（" songname"）。值;



// var song2 = from p in 

songlist.DataContext = song;

file xml:

<Music>
<song>
<songalbum>Fearless</songalbum>
<songid>1</songid> 

<songname>Love Story</songname>
<songlinks>/Album/Fearless/Taylor Swift - Taylor Swift _ Album 320 lossless.mp3</songlinks>
</song>
</Music>

code xaml

var xmlelem = XElement.Load(@"XMLlistmusic.xml");
var song = from p in xmlelem.Descendants("song")
//orderby prod.Element("songname").Value
select p.Element("songname").Value;

// var song2=from p in 
songlist.DataContext = song;

我想给quey一个"where"  

ex：通过songname给歌曲链接...

谢谢你，

推荐答案

在这里你去！

var xmlelem = XElement.Load(@"XMLlistmusic.xml");
var song = from p in xmlelem.Descendants("song")
           where p.Element("songname").Value.Equals("Love Story")
           select p.Element("songlinks").Value;
