如何将Excel和xml文件数据保存到数据库

Inherits System.Windows.Forms.Form
    Dim DS1 As New System.Data.DataSet
    Dim DS2 As New System.Data.DataSet

     Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
        Dim MyConnection As System.Data.OleDb.OleDbConnection

        MyConnection = New System.Data.OleDb.OleDbConnection( _
              "provider=Microsoft.Jet.OLEDB.4.0; " & _
              "data source=e:\BOOK1.XLS; " & _
              "Extended Properties=Excel 8.0;")
        ' Select the data from Sheet1 of the workbook.
        MyCommand = New System.Data.OleDb.OleDbDataAdapter( _
              "select * from [Sheet1$]", MyConnection)
'或者是DS1.ReadXml("c:\abcd.xml")

        MyCommand.Fill(DS1, "handle")
        DataGrid1.DataSource = DS1
        MyConnection.Close()

    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Try
            Dim j As Integer
            Dim person_id, information_id, handle As String
            Dim handle_time As System.DateTime
            'If Me.SqlConnection1.Close() Then
            Me.SqlConnection1.Open()
            'End If
            For j = 1 To DS1.Tables("handle").Rows.Count - 1

                Me.SqlDataAdapter1.InsertCommand.Parameters("@person_id").Value = DS1.Tables("handle").Rows(j).Item(0)
                Me.SqlDataAdapter1.InsertCommand.Parameters("@information_id").Value = DS1.Tables("handle").Rows(j).Item(1)
                'Me.SqlDataAdapter1.InsertCommand.Parameters("@handle").Value = DS1.Tables("handle").Rows(j).Item(2)
                Me.SqlDataAdapter1.InsertCommand.Parameters("@handle_time").Value = CDate(DS1.Tables("handle").Rows(j).Item(3))
                Me.SqlDataAdapter1.InsertCommand.ExecuteNonQuery()
            Next

            'MessageBox.Show(SqlDataAdapter1.InsertCommand.CommandText)
            Me.SqlConnection1.Close()
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
   End Sub

一个例子，原理就是先把Excel或xml文件的数据通过DataSet读到Datagrid中，再一个个取出保存到数据库中去。
