DataGrdid 利用结果集反向转换成数据List

                        //通过反向解析datagird，得到List
                        ObservableCollection<rz_cpdfbInfo> List2 = new ObservableCollection<rz_cpdfbInfo>();  //初始化List2

                        //List2 = this.uiWdfmxList.dg_source;
                        if (this.uiWdfmxList.dg_source.ItemsSource != null)
                        {
                            foreach (rz_cpdfbInfo obj in this.uiWdfmxList.dg_source.ItemsSource)
                            {
                                rz_cpdfbInfo m = new rz_cpdfbInfo();
                                m.ckje = obj.ckje;

                                m.rzlbsm = obj.rzlbsm;
                                List2.Add(m);
                            }

                        }
