Dim domXmlDocument As System.Xml.XmlDocument Dim tmpPath As String = AppTempFilePath Dim xmlFile As String = tmpPath + "\testXml.xml"
'窗体加载事件 Private Sub TestXml_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load '读xml过程测试通过 Dim domXmlDocument As System.Xml.XmlDocument Dim tmpPath As String = AppTempFilePath Dim xmlFile As String = tmpPath + "\testXml.xml" Dim reader As System.Xml.XmlReader = Nothing Try reader = New Xml.XmlTextReader(xmlFile) 'reader. While reader.Read Me.lboxXml.Items.Add(reader.Name + reader.Value) End While
Catch ex As Exception MsgBox(ex.Message) Finally If Not (reader Is Nothing) Then reader.Close() End If End Try
End Sub
'载入xml事件 Private Sub btnXmlLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnXmlLoad.Click 'Me.lboxXml.Items.Clear() ''读xml过程测试通过
'Dim reader As System.Xml.XmlReader = Nothing 'Try ' reader = New Xml.XmlTextReader(xmlFile) ' While reader.Read ' Me.lboxXml.Items.Add(reader.Name + ":" + reader.Value) ' End While 'Catch ex As Exception ' MsgBox(ex.Message) 'Finally ' If Not (reader Is Nothing) Then ' reader.Close() ' End If 'End Try Dim ds As New DataSet Try '如果直接使用ds做datasource则不会展开datagrid，用dv则可以直接显示正确。 ds.ReadXml(xmlFile) Dim tb As DataTable Dim dv As DataView tb = ds.Tables(0) dv = New DataView(tb) DataGrid1.DataSource = dv 'DataGrid1.DataMember = "testXmlMember" 'DataGrid1.DataMember = "employeefname" 'Dim dxd As New XmlDataDocument Catch ex As Exception MsgBox(ex.Message.ToString) End Try
End Sub
'保存新建xml内容事件 Private Sub btnSaveNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSaveNew.Click
Dim myTW As New XmlTextWriter(tmpPath + "\testXmlWrite.xml", Nothing)
myTW.WriteStartDocument() myTW.Formatting = Formatting.Indented
myTW.WriteStartElement("Team")
myTW.WriteStartElement("player") myTW.WriteAttributeString("Name", "George Zip") myTW.WriteAttributeString("Position", "QB") myTW.WriteElementString("Nickname", "Zippy") myTW.WriteElementString("JerseyNumber", XmlConvert.ToString(7))
myTW.WriteEndElement()
myTW.WriteEndElement()
myTW.WriteEndDocument()
myTW.Close()
End Sub
对于修改datagrid中指定内容并保存到xml中还不会,弄明白了,在vb.net与xml读写的2中写出来!
