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

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 :-)）

第一次写blog，有什么写得不对的，高手请指点了

使用vb.net连接到数据库并执行命令。
