其中的ID列表示机构的ID,用来和员工信息中的机构ID进行"关联".


再来看关键代码
                DataSet ds =new DataSet();

                DataTable dtOrgan =new DataTable();
                dtOrgan.Columns.Add("ID",typeof(string));
                dtOrgan.Columns.Add("OrganName",typeof(string));
                ...
                /*...往机构表中灌数据...*/
                ds.Tables.Add(dtOrgan);

                DataTable dtEmployee =new DataTable();
                dtEmployee.Columns.Add("OrganID",typeof(string));
                dtEmployee.Columns.Add("EmployeeName",typeof(string));
                ...
                /*...往员工表中灌数据...*/

                ds.Tables.Add(dtEmployee);
                ds.Relations.Add("parentchild",ds.Tables[0].Columns["ID"],ds.Tables[1].Columns["OrganID"]);
                dgList.DataSource = ds.Tables[0].DefaultView;
                dgList.DataBind();

最主要的就是利用了DataSet的Relations的属性,通过属性来将父子表关联起来,然后进行数据的绑定.最后,在WEB上运行出来的效果如下所示:
