[VB.NET+XML]完成简单程序配置

简单的一个应用例子 ，只是简单的操作XML文件，在实际的应用上可以先建一个配置类保存状态。

XML文件的结构：

1

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

2

<config>

3

<Function Name="a" Checked="false" />

4

<Function Name="b" Checked="false" />

5

<Function Name="c" Checked="false" />

6

<Function Name="d" Checked="false" />

7

</config>

具体的程序：需要一个CheckedListBox,两个Button

1

Public doc As New XmlDocument

2

Public rootnode As XmlElement

3

Public strPathConfig As String = Application.StartupPath & "\config.xml"

4

Public intNum As Int16

5

Private Sub Button1_Click()Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

6

WriteConfig()

7

End Sub

8

Private Sub Form1_Load()Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

9

'做准备工作

10

doc.Load(strPathConfig)

11

rootnode = doc.DocumentElement

12

intNum = rootnode.ChildNodes.Count - 1

13

'

14

LoadConfig()

15

End Sub

16

'添加到CheckedListBox

17

Function LoadConfig()Function LoadConfig()

18

Dim i As Int16

19

For i = 0 To intNum

20

CheckedListBox1.Items.Add(rootnode.ChildNodes(i).Attributes(0).Value, CType(rootnode.ChildNodes(i).Attributes(1).Value, Boolean))

21

Next

22

End Function

23

'确定，然后写入XML

24

Function WriteConfig()Function WriteConfig()

25

Dim i As Int16

26

Dim str As String

27

For i = 0 To intNum

28

rootnode.ChildNodes(i).Attributes(1).Value = CheckedListBox1.GetItemChecked(i).ToString

29

Next

30

doc.Save(strPathConfig)

31

End Function

32

33

Private Sub Button2_Click()Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

34

'需要清除CheckedListBox内的Items

35

CheckedListBox1.Items.Clear()

36

LoadConfig()

37

End Sub
