vb.net中怎么创建xml文件并写数据

[led0led]

我要创建一个xml文件 并在里面写上“地址”“邮编”数据 大家帮帮忙

[essenza]

给你一个函数:
Private Sub WriteXmlToFile(ByVal thisDataSet As DataSet)
If thisDataSet Is Nothing Then
Return
End If

Dim filename As String = "myXmlDoc.xml"

Dim myFileStream As New System.IO.FileStream(filename, System.IO.FileMode.Create)

Dim myXmlWriter As New System.Xml.XmlTextWriter(myFileStream, System.Text.Encoding.Unicode)

thisDataSet.WriteXml(myXmlWriter)
myXmlWriter.Close()
End Sub


把dataset中的内容写入XML

不用这么麻烦吧……
直接datatable.writexml(filename)就行了。

这样：
Dim dt as new datatable
dt.columns.add("地址")
dt.columns.add("邮编")
dt.tablename="Ads"

Dim dr as datarow = dt.newrow
dr("地址")="大连"
dr("邮编")="116000"

dt.rows.add(dt)

dt.WriteXml(Application.StartupPath & "mydata.xml")
