　　asp.net|server|访问在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>
<body>
   <h3><font face="Verdana">Simple SELECT to a DataGrid Control
   </font></h3>
   <ASP:DataGrid id="MyDataGrid" runat="server"
      Width="600"
      BackColor="#ccccff"
      BorderColor="black"
      ShowFooter="false"
      CellPadding=3
      CellSpacing="0"
      Font-Name="Verdana"
      Font-Size="8pt"
      HeaderStyle-BackColor="#aaaadd"
