VB.NET 导出数据到EXCEL中

----------VB.NET 导出数据到EXCEL中-------------

  在引用当中引入Microsoft Excel 11.0 Object Library

        Dim oExcel As New Excel.Application

        Dim obook As Excel.Workbook

        Dim oSheet As Excel.Worksheet

        Dim DataArray(2000, 2000) As Integer

        obook = oExcel.Workbooks.Open("c:/1.xls")

        oSheet = obook.Worksheets(1)

        oSheet.Name = "ok"

        Dim myAdapter As New OleDb.OleDbDataAdapter("select * from list", Module1.dbConn)

        Dim mydataset As New DataSet

        myAdapter.Fill(mydataset, "list")

        DataGrid1.DataSource = mydataset.Tables("list")

        Dim i As Integer

        Dim iCount As Integer

        iCount = mydataset.Tables("list").Rows.Count

        For i = 0 To iCount - 1

            DataArray(i, 0) = DataGrid1.Item(i, 0)

        Next

        oSheet.Range("b1").Resize(100, 1).Value = DataArray

        obook.Save()

        oExcel.Quit()

添加数据到EXCEL的行（列）,源数据的数组要与EXCEL的行（列）对应。

上面代码使用的是DataGrid的控件，如果使用Table也是一样一样的哦

数组大小可以自己来定义，如果数据的数量大于数组的范围，那么以数组为准（谁叫要用数组输出呢 :-)

）

BTW：机器要安装了office才能够引用Microsoft Excel 11.0 Object Library

路径是*/Microsoft office/office11/execl.exe

第一次写blog，有什么写得不对的，高手请指点了
