ArcOjbects 获取当前地图选择要素属性信息 

 ISelection pSelection = MainMapControl.Map.FeatureSelection;
            IEnumFeatureSetup iEnumFeatureSetup = (IEnumFeatureSetup)pSelection;
            iEnumFeatureSetup.AllFields = true;
            IEnumFeature pEnumFeature = (IEnumFeature)iEnumFeatureSetup;
            pEnumFeature.Reset();
            IFeature pFeature = pEnumFeature.Next();
            if (pFeature != null)
            {
                int index = pFeature.Fields.FindField("HeritageNu");
                if (index != -1)
                {
                    string hid = pFeature.get_Value(index).ToString();
                    .....
                }
            }
IEnumFeatureSetup iEnumFeatureSetup = (IEnumFeatureSetup)pSelection;
            iEnumFeatureSetup.AllFields = true;
这两句代码非常重要，不然获取不到选中要素属性信息
