上面的问题还没解决,新问题又来了。书上一直是用ADO.NET来做连接的对象的,但是今天实验了N次都不成功。上网请教高手,他说ASP.NET现在基本不怎么用ADO的了(注意:他说的是ADO,而不是ADO.NET)然后我自己又上网去找连接数据库的实例,结果都如他说的。现在都用OLEDB来连接,我下载了一个实例来做研究。同时他也发了一本英文的入门教材给我。
如果真是我的书的问题的话,事情可能就有点麻烦了。那我就必须换一本教材了,还是去图书馆找吧,哎……
基本确认ADO.NET似乎已经不再被应用,于是我决定在以后还是改用OLEDB。连接事例源代码如下:

大家好,以下是有关ASP.net连接Access数据库的例程,
在这里和大家分享一下:
Asp.net连接Access数据库例程详解:
<%@ Import Namespace="System.Data" %>
<%@ Import NameSpace="System.Data.OleDb" %>
<script laguage="VB" runat="server">
Dim myConnection As OleDbConnection
Dim myCommand As OleDbCommand
sub page_load(sender as Object,e as EventArgs)
'1.连接数据库
dim dbname as string
dbname=server.mappath("authors.mdb")
myConnection = New OleDbConnection( "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source="&dbname )
myConnection.Open()
la1.text="Connection Opened!"
'2.添加记录
myCommand = New OleDbCommand( "Insert INTO Authors(Authors,country) Values('Simson','usa')", myConnection )
myCommand.ExecuteNonQuery()
la2.text="New Record Inserted!"
'3 更新数据(Access)
myCommand = New OleDbCommand( "UPDATE Authors SET Authors='Bennett' WHERE Authors = 'Simson'", myConnection )
myCommand.ExecuteNonQuery()
la3.text="Record Updated!"
'4 删除数据(access)
myCommand = New OleDbCommand( "DELETE FROM Authors WHERE Authors = 'David'", myConnection )
myCommand.ExecuteNonQuery()
la4.text="Record Deleted!"
'5 使用DateGrid显示数据
myCommand = New OleDbCommand( "select * FROM Authors", myConnection )
MyDataGrid.DataSource=myCommand.Executereader()
MyDataGrid.DataBind()
end sub
