往要素集里添加数据

IFeatureClass dljxFC = Env.Instance.KMap.GetFeatureClassByName(Env.Instance.DefaultValue.DLJX_TableName);
                if (list != null)
                {
                    //List<IGeometry> dljxList = new List<IGeometry>();
                    foreach (IFeature item in list)
                    {
                        List<IGeometry> dljxList = CommonAPI.GenerateDLJX(item, dljxFC);
                        if (dljxList != null)
                        {
                            foreach (IGeometry line in dljxList)
                            {
                                IFeatureBuffer buffer = dljxFC.CreateFeatureBuffer();
                                buffer.Shape = line;
                                IFeatureCursor cursor = dljxFC.Insert(true);
                                object oid = cursor.InsertFeature(buffer);
                                cursor.Flush();
                                Marshal.ReleaseComObject(cursor);
                            }
                        }
                    }
                }
list 为图斑列表

dljxFC 可以是要素 IFeatureClass
