在ado.net中我們很少甚至不用recordset今天我就向大家展示如何在ado.net中使用recordset
新建一個vb.net應用程序
在窗體上添加一個datagrid控件
然后，項目-->添加引用--〉com->
選擇Microsoft ActiveX Data Objects 2.7 Library
這樣在引用一欄我們就看到新加入一項ADODB
我們將其與其他命名空間一起倒入
Imports System.Data
Imports System.Data.OleDb
Imports ADODB
整個代碼如下（使用中文officeXp事例數據庫-因為是中文所以表明字段名都是中文，你也可以利用其他的數據庫）
Imports System.Data
Imports System.Data.OleDb
Imports ADODB

Public Class Form1
Inherits System.Windows.Forms.Form

#Region " Windows 窗體設計器生成的代碼 "

Public Sub New()
MyBase.New()

'該調用是 Windows 窗體設計器所必需的。
InitializeComponent()

'在 InitializeComponent() 調用之后添加任何初始化

End Sub

'窗體重寫處置以清理組件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub

'Windows 窗體設計器所必需的
Private components As System.ComponentModel.IContainer

'注意：以下過程是 Windows 窗體設計器所必需的
'可以使用 Windows 窗體設計器修改此過程。
'不要使用代碼編輯器修改它。
Friend WithEvents DataGrid1 As System.Windows.Forms.DataGrid
<System.Diagnostics.DebuggerStepThrough()> Private Sub InitializeComponent()
Me.DataGrid1 = New System.Windows.Forms.DataGrid()
CType(Me.DataGrid1, System.ComponentModel.ISupportInitialize).BeginInit()

Me.Name = "Form1"

End Sub

#End Region

OK怎么樣試一試看看！
