DataTable操作相关实例

代码

         public  DataSet GetChildDepartmentsByUserId(Guid userId) 
        {
            DataSet ds  =   new  DataSet();
             try  
            {
                OrgChartDB.OrgChart_PermissionDataTable pdt  =  permissionTableAdapter.GetDataByUserId(userId);
                 for  ( int  i  =   0 ; i  <  pdt.Rows.Count; i ++ )
                {
                    Guid deptId  =  pdt[i].DepartmentId;
                    OrgChartDB.OrgChart_DepartmentsDataTable ddtAllChildDepartments  =  departmentsTableAdapter.GetChildDepartmentByDepartmentId(pdt.Rows[ 0 ][ 0 ]);
                    ds.Tables.Add(ddtAllChildDepartments);
                }
                 // OrgChartDB.OrgChart_DepartmentsDataTable ddtAllChildDepartments = departmentsTableAdapter.GetChildDepartmentByDepartmentId(pdt.Rows[0][0]);
                 return  ds;

            }
             catch  (Exception ex) 
            {

            }
        }

根据一个datatable中的一列值获取多个datatable并加入到dataset中。

注：此处pdt[i]返回PermissionDataRow能点出属性。

pdt.rows[0].[i]返回DataRow，点不出属性。
