VB.NET導出數據到EXCEL中

----------VB.NET 導出數據到EXCEL中-------------

在引用當中引入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()

添加數據到EXCEL的行（列）,源數據的數組要與EXCEL的行（列）對應。

上面代碼使用的是DataGrid的控件，如果使用Table也是一樣一樣的哦

數組大小可以自己來定義，如果數據的數量大於數組的范圍，那麼以數組為准（誰叫要用數組輸出呢 :-)）

BTW：機器要安裝了office才能夠引用Microsoft Excel 11.0 Object Library

路徑是*\Microsoft office\office11\execl.exe

第一次寫blog，有什麼寫得不對的，高手請指點了
