在ASP.NET中访问SQL Server数据库有两种方法,它们是System.Data.OleDb和System.Data.SqlClient.下面这段程序以System.Data.SqlClient为例访问本地数据库服务器.

首先导入名字空间:System.Data和System.Data.SqlClient.详细代码看源程序.

<%@ Import Namespace="System.Data" %>

<%@ Import Namespace="System.Data.SqlClient" %>

<html>

<script language="C#" runat="server">

protected void Page_Load(Object Src, EventArgs E )

{

SqlConnection myConn = new SqlConnection("server=localhost;uid=sa;pwd=;database=pubs");

//创建对象SqlConnection

string strSQL="SELECT au_id,au_lname,au_fname,phone,address,city,zip FROM authors";

SqlDataAdapter myCmd = new SqlDataAdapter(strSQL, myConn);

//创建对象SqlDataAdapter

DataSet ds = new DataSet();

//创建对象DataSet

myCmd.Fill(ds);

//填充数据到Dataset

DataView source = new DataView(ds.Tables[0]);

MyDataGrid.DataSource = source ;

MyDataGrid.DataBind();

//将数据绑定到DataGrid

}

</script>
