arcgis开发常用源码 1.点上生成面的代码 if (m_pFeatureLayer.FeatureClass.ShapeType == esriGeometryType.esriGeometryPolygon) { IPointCollection m_pPointCollection = new PolygonClass(); object missing = Type.Missing; int icount = newFeature.XLIST.Count; if (icount < 3) return; for (int i = 0; i < icount; i++) { IPoint point = new PointClass(); point.PutCoords(newFeature.XLIST, newFeature.YLIST); m_pPointCollection.AddPoint(point, ref missing, ref missing); } IPolygon m_pPolygon = m_pPointCollection as IPolygon; if (m_pPolygon == null) { System.Windows.Forms.MessageBox.Show("null"); return; } else { ITopologicalOperator pTopo = m_pPolygon as ITopologicalOperator; if (pTopo != null) { pTopo.Simplify(); } } IWorkspaceEdit m_pWorkspaceEdit = m_EngineEditor.EditWorkspace as IWorkspaceEdit; m_pWorkspaceEdit.StartEditOperation(); IFeature m_pFeature = m_pFeatureLayer.FeatureClass.CreateFeature(); m_pFeature.Shape = m_pPolygon as IGeometry; m_pFeature.Store(); m_pWorkspaceEdit.StopEditOperation(); }
