在asp.net中訪問sql server數據庫有兩種方法，它們是system.data.oledb和system.data.sqlclient．下面這段程序以system.data.sqlclient為例訪問本地數據庫服務器．
首先導入名字空間：system.data和system.data.sqlclient．詳細代碼看源程序．
<%@ 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");
//創建對象sqlconnection
string strsql="select au_id,au_lname,au_fname,phone,address,city,zip from authors";
sqldataadapter mycmd = new sqldataadapter(strsql, myconn);
//創建對象sqldataadapter
dataset ds = new dataset();
//創建對象dataset
mycmd.fill(ds);
//填充數據到dataset
dataview source = new dataview(ds.tables[0]);
mydatagrid.datasource = source ;
mydatagrid.databind();
//將數據綁定到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"
maintainstate="false"
/>
</body>
</html>
