二．用Visual C#往SQL SERVER數據庫中插入記錄：
（1）用Visual C#往Access 2000和SQL SERVER添加記錄的主要區別在于使用了不同的數據庫引擎。在編寫程序之前，首先假設數據庫服務器名稱為：server1，要訪問的數據庫名稱為：data1，數據表名稱為：books。用戶名為：sa。其中數據表的數據結構和Access 2000的表的結構相同。下面是程序中打開SQL SERVER的數據引擎程序代碼：
// 設定數據連接字符串，此字符串的意思是打開Sql server數據庫，服務器名稱為server1,數據庫為data1
string strCon = "Provider = SQLOLEDB.1 ; Persist Security Info = False ; User ID = sa ; Initial Catalog = data1 ; Data Source = server1 " ;
OleDbConnection myConn = new OleDbConnection ( strCon ) ;
myConn.Open ( ) ;

（2）.用Visual C#往SQL SERVER 數據庫中插入記錄的源程序代碼( add02.cs )：
using System ;
using System.Drawing ;
using System.ComponentModel ;
using System.Windows.Forms ;
using System.Data.OleDb ;
using System.Data ;
//導入程序中使用到的名稱空間
public class DataAdd : Form {

private BindingManagerBase myBind ;
//定義在程序中要使用的組件
public DataAdd ( ) {
//連接到一個數據庫
GetConnected ( ) ;
// 對窗體中所需要的內容進行初始化
InitializeComponent ( );
}
//釋放程序使用過的所以資源
public override void Dispose ( ) {
base.Dispose ( ) ;
components.Dispose ( ) ;
}
public static void Main ( ) {
Application.Run ( new DataAdd ( ) ) ;
}
public void GetConnected ( )
{
try{
// 設定數據連接字符串，此字符串的意思是打開Sql server數據庫，服務器名稱為server1,數據庫為data1，用戶名為sa。
string strCon = "Provider = SQLOLEDB.1 ; Persist Security Info = False ; User ID = sa ; Initial Catalog = data1 ; Data Source = server1 " ;
OleDbConnection myConn = new OleDbConnection ( strCon ) ;
myConn.Open ( ) ;
string strCom = " SELECT * FROM books " ;
//創建一個 DataSet
myDataSet = new DataSet ( ) ;
//用 OleDbDataAdapter 得到一個數據集
OleDbDataAdapter myCommand = new OleDbDataAdapter ( strCom , myConn ) ;
//把Dataset綁定books數據表
myCommand.Fill ( myDataSet , "books" ) ;
//關閉此OleDbConnection
myConn.Close ( ) ;
}
catch ( Exception e )
{
MessageBox.Show ( "連接錯誤! " + e.ToString ( ) , "錯誤" ) ;
}
}

{

三．總結：
本文主要是通過二個程序的例子來具體說明用Visual C#如何往遠程數據庫--SQL SERVER和本地數據庫-- Access 2000中插入記錄。對于其他類型的數據庫也可以比照這二個這二個數據庫來處理，一般來說，用Visual C#處理數據庫只是在選用數據庫引擎上有較大的差別，在程序中的具體設計和處理上，還是很類似的。最后希望此篇文章能對你的數據庫編程有所幫助。
