arcgis开发常用源码

1.点上生成面的代码

if(m_pFeatureLayer.FeatureClass.ShapeType==esriGeometryType.esriGeometryPolygon)

{IPointCollectionm_pPointCollection=newPolygonClass();objectmissing=Type.Missing;

inticount=newFeature.XLIST.Count;if(icount3)return;for(inti=0;iicount;i++)

{IPointpoint=newPointClass();point.PutCoords(newFeature.XLIST,newFeature.YLIST);

m_pPointCollection.AddPoint(point,refmissing,refmissing);}IPolygonm_pPolygon=

m_pPointCollectionasIPolygon;if(m_pPolygon==null)

{System.Windows.Forms.MessageBox.Show(null);return;}else{ITopologicalOperator

pTopo=m_pPolygonasITopologicalOperator;if(pTopo!=null){pTopo.Simplify();}}

IWorkspaceEditm_pWorkspaceEdit=m_EngineEditor.EditWorkspaceasIWorkspaceEdit;

m_pWorkspaceEdit.StartEditOperation();IFeaturem_pFeature=

m_pFeatureLayer.FeatureClass.CreateFeature();m_pFeature.Shape=m_pPolygonas

IGeometry;m_pFeature.Store();m_pWorkspaceEdit.StopEditOperation();}

2.文件的打开保存另存的代码
