在web.config中配置好连接字符串：

<connectionStrings>
<add name="Movies_Conn" connectionString="Data Source=./express;Initial Catalog=WebSiteTest;User ID=sa;Password=123;Persist Security Info=True;"
providerName="System.Data.SqlClient" />
</connectionStrings>

页面代码：

<%@ Page Language="C#" %>
<%@ Import Namespace ="System.Data.SqlClient" %>
<%@ Import Namespace ="System.Web.Configuration" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script runat ="server" >

void Page_Load()
{
string _connectionString = WebConfigurationManager.ConnectionStrings["Movies_Conn"].ConnectionString;

SqlConnection con = new SqlConnection(_connectionString );
SqlCommand cmd = new SqlCommand("Waitfor Delay '0:0:03';select title,director from Movies",con);
con.StatisticsEnabled = true;

using (con)
{

con.Open();
SqlDataReader reader = cmd.ExecuteReader();
}

grdStats.DataSource = con.RetrieveStatistics();
grdStats.DataBind();

}
</script>
