经常需要在数据库与Execl之间互导数据。net时代，ADO.NET可以使用使用Microsoft.Jet.OleDb访问访问Excel，网上已经有很多类似的资源，最典型也是最简单的可能如下：（asp.net环境）

[code]Code

Dim strConnE As String = "Provider=Microsoft.Jet.OLEDB.4.0;" _

& "Data Source='" & WebPath _

& "';Extended Properties='Excel 8.0;IMEX=1'"

Dim connE As OleDbConnection = New OleDbConnection(strConnE)

connE.Open()

Dim cmd As OleDbCommand = New OleDbCommand("SELECT * FROM [Sheet1$]", connE)

Dim da As OleDbDataAdapter = New OleDbDataAdapter

da.SelectCommand = cmd

Dim ds As DataSet = New DataSet

da.Fill(ds, "myExcel")
