VB.NET linq to xml

首先一个名称为DATA.XML文件，内容如下

<?xml version="1.0" encoding="utf-8" ?>
<mykeys>
  <myitem ID="1" order="1" kyes="F1" title="F1标题">
    F1内容F1内容F1内容F1内容F1内容
    F1内容F1内容F1内容
    F1内容F1内容
    F1内容
    F1内容F1内容F1内容
  </myitem>
  <myitem ID="2" order="2" kyes="F2" title="F2标题">
    F2内容
    F2F2内容F2内容F2内容
    F2内容F2内容F2内容F2内容
    F2内容F2内容F2内容F2内容
    F2内容
  </myitem>
</mykeys>

建立一个操作类，

Public Class myKeysXml
    Public Structure DTinf
        Public ID As Integer
        Public order As Integer
        Public kyes As String
        Public title As String
        Public sbody As String
    End Structure
     
End Class

使用之前导入

Imports System.Xml.Linq

下面是点击一个按钮执行的操作。

Private Sub Button1_Click(sender As Object,e As EventArgs) Handles Button1.Click
         Dim SXML As XElement = XElement.Load(Application.StartupPath & "\data.xml")
         If SXML Is nothing Then Exit Sub
         Dim Rows = From item In SXML.Elements("myitem")
                    Order By item.Attribute("order").Value
                    Select item

        Dim itemList As New List(Of myKeysXml.DTinf)
         For Each it As XElement In Rows
             Dim item As New myKeysXml.DTinf
             item.ID = it.Attribute("ID")Value
             item.kyes = it.Attribute("kyes")Value
             item.order = it.Attribute("order")Value
             item.title = it.Attribute("title")Value
             item.sbody = it.Value

            itemList.Add(item)
         Next
          
     End Sub

取得itemList的序列，然后大家怎么使用就可以自由发挥了。
