        string sql2 = "select * from contact";
        SqlCommand newcmd = new SqlCommand(sql2, myconn);
        SqlDataAdapter sda = new SqlDataAdapter(newcmd);
        DataSet ds = new DataSet();
        sda.Fill(ds, "contact");
        this.GridView1.DataSource = ds.Tables["contact"];
        this.GridView1.DataBind();
        myconn.Close();
    }
}

其他的改 ,删等原理相同,参考以上代码即可.
