AE中如何由IFeature 如何获取所对应的FeatureClass

private void OnDeleteFeatureMethod(object o) { IFeature pFeature = o as IFeature; IFeatureClass pFeatureClass = pFeatureClass as IFeatureClass; for (int i = 0; i < axMapControl1MapLayerCount;i++ ) { IFeatureLayer iFeatureLayer = axMapControl1get_Layer(i) as IFeatureLayer; IFeatureClass iFeatureCla = iFeatureLayerFeatureClass; if (iFeatureCla == pFeatureClass) { IWorkspace pWorkSpace = m_EngineEditorEditWorkspace; textBox3Text += " *** 作的文件全路径:" + pWorkSpacePathName + "\\" + axMapControl1get_Layer(i)Name + "shp " + "\r\n"; break; } } if (pFeatureShapeGeometryType == esriGeometryTypeesriGeometryPoint) { IGeometry iGe = pFeatureShape; IPoint ipo = new PointClass(); ipo = iGe as IPoint; int a = 0; int b = 0; axMapControl1FromMapPoint(ipo, ref a, ref b); textBox3Text += "删除的点的ID号：" + pFeatureOID + "，坐标：(" + a + "," + b + ")" + "\r\n"; } else if (pFeatureShapeGeometryType == esriGeometryTypeesriGeometryPolygon) { textBox3Text += "删除的多边形对象的ID号：" + pFeatureOID + "，坐标："; IPolygon pPolygon = (IPolygon)pFeatureShape; int a = 0; int b = 0; //把该feature强制转换为一个点的集合，再取点的坐标 IPointCollection pPointCollection = pPolygon as IPointCollection; for (int i = 0; i < pPointCollectionPointCount - 1; i++) { IPoint ipo = pPointCollectionget_Point(i); axMapControl1FromMapPoint(ipo, ref a, ref b); textBox3Text += "(" + a + "," + b + ")" + "\t"; } textBox3Text += "\r\n"; } else if (pFeatureShapeGeometryType == esriGeometryTypeesriGeometryPolyline) { textBox3Text += "删除的线对象的ID号：" + pFeatureOID + "，其坐标："; IPolyline pPolygon = (IPolyline)pFeatureShape; int a = 0; int b = 0; //把该feature强制转换为一个点的集合，再取点的坐标 IPointCollection pPointCollection = pPolygon as IPointCollection; for (int i = 0; i < pPointCollectionPointCount; i++) { IPoint ipo = pPointCollectionget_Point(i); axMapControl1FromMapPoint(ipo, ref a, ref b); textBox3Text += "(" + a + "," + b + ")" + "\t"; } textBox3Text += "\r\n"; } axMapControl1ActiveViewPartialRefresh(esriViewDrawPhaseesriViewGeography, null, null); }
