怎么用dataset将新的记录添加到数据库

代码如下图
protected void Button1_Click(object sender, EventArgs e)
        {   DataSet1 ds = new DataSet1();
            DataSet1.STAFFRow newrow = ds.STAFF.NewSTAFFRow();
            newrow.BeginEdit();
            int staffid=88;
            newrow.CLERKID = staffid;
            newrow.NAME = this.TextBox1.Text.ToString();
            newrow.SEX = this.DropDownList1.Text.ToString();
            newrow.MERRY = this.TextBox2.Text.ToString();
            newrow.DEPT = this.DropDownList2.Text.ToString();
            newrow.DUTY = this.TextBox3.Text.ToString();
            newrow.SALARY = Decimal.Parse(this.TextBox4.Text.ToString());
            newrow.TEL = this.TextBox5.Text.ToString();
            newrow.ADDRESS = this.TextBox6.ToString();
            newrow.EndEdit();
            ds.STAFF.AddSTAFFRow(newrow);
            if (BLLhelp.add2(ds) > 0) ;
             Response.Write("<script>alert('插入成功')</script>");
}
 public DataSet add2(DataSet ds)
        {
            string str8 = "p_staff_i";
            DALhelp d = new DALhelp();
         return Int32.Parse(d.exce2(str8, ds));}
 public string exce2(string str, DataSet ds)
        {
            SqlConnection conn = DALhelp.con();
             conn.Open();
             SqlCommand com = new SqlCommand(str, conn);
                com.CommandType = CommandType.StoredProcedure;
                SqlDataAdapter da = new SqlDataAdapter();
                da.Fill(ds);
                da.Update(ds);
             
} dataset 数据库

补充：.NET技术 ,  ASP.NET
