sql连接错误
程序如下：
<%@   Import   Namespace   =   "System.Data.SqlClient "%>
<%@   Import   Namespace   =   "System.Data "%>
<script   language   =   "C# "   runat   =   "server ">
protected   void   Page_Load(Object   sender,EventArgs   e)
{

string   strConn   =   "   server   =   (LENOVO-06164154);database   =   pubs;   uid   =sa;   pwd   =admin   ";
SqlConnection   Conn   =   new   SqlConnection(strConn);
string   sql   =   "select   *   from   Authors ";
SqlDataAdapter   Comm   =   new   SqlDataAdapter(sql,Conn);
DataSet   ds   =   new   DataSet();
Comm.Fill(ds, "Authors ");
MyDataGrid.DataSource   =   ds.Tables[ "Authors "].DefaultView;
MyDataGrid.DataBind();
}
</script>  

<asp:DataGrid   ID= "MyDataGrid "   Runat   =   "server "   />
错误信息如下：
