#实现添加数据、地图放大、缩小、漫游、全景视图、鹰眼图的操作(ICommand、ITool)

ICommand接口：属于ESRI.ARCGIS.SystemUI命名空间(引用)

1.添加数据：

//添加数据private void button1_Click(object sender, EventArgs e){ICommand addfile = new ControlsAddDataCommandClass();addfile.OnCreate(axMapControl1.Object);addfile.OnClick();}
//地图放大private void button2_Click(object sender, EventArgs e){if (axMapControl1.CurrentTool == null){ICommand identify;ITool identifytool = new ControlsMapZoomInToolClass();axMapControl1.CurrentTool = identifytool;//由于ITool中不存在绑定MapControl的方法，所以需要进行接口跳转到ICommand来进行绑定MapControlidentify = identifytool as ICommand;identify.OnCreate(axMapControl1.Object);identify.OnClick();}else{axMapControl1.CurrentTool = null;}}//地图缩小private void button3_Click(object sender, EventArgs e){if (axMapControl1.CurrentTool == null){ICommand identify;ITool identifytool = new ControlsMapZoomOutToolClass();axMapControl1.CurrentTool = identifytool;identify = identifytool as ICommand;identify.OnCreate(axMapControl1.Object);identify.OnClick();}else{axMapControl1.CurrentTool = null;}}//全图显示private void button4_Click(object sender, EventArgs e){ICommand mapfull=new ControlsMapFullExtentCommandClass();mapfull.OnCreate(axMapControl1.Object);mapfull.OnClick();}//漫游：private void button5_Click(object sender, EventArgs e){if (axMapControl1.CurrentTool == null){ICommand identify;ITool identifytool = new ControlsMapPanToolClass();axMapControl1.CurrentTool = identifytool;identify = identifytool as ICommand;identify.OnCreate(axMapControl1.Object);identify.OnClick();}else{axMapControl1.CurrentTool = null;}}//鹰眼图1(只能对Mxd文档进行鹰眼图显示)//该事件axMapControl1_OnMapReplaced的意思是当当地图文档发生了改变就会执行里面的代码。private void axMapControl1_OnMapReplaced(object sender, IMapControlEvents2_OnMapReplacedEvent e){IMap pmap = axMapControl1.Map;int i;for (i = 0; i < pmap.LayerCount; i++){//复制对象IObjectCopy objectcopy = new ObjectCopyClass();object toCopyLayer = axMapControl1.get_Layer(pmap.LayerCount - 1 - i);object copiedLayer = objectcopy.Copy(toCopyLayer);//将复制的对象添加到map2axMapControl2.Map.AddLayer(copiedLayer as ILayer);}//保证map2里面的范围始终是map1中的范围axMapControl2.Extent = axMapControl1.FullExtent;}//打开地图文档private void button6_Click(object sender, EventArgs e){axMapControl1.LoadMxFile("D:\\ARCEngineDATA\\map.mxd");}//鹰眼图矩形框实现//axMapControl1_OnExtentUpdated事件，当MapControl视图的范围发生了改变，就会触发这个时间private void axMapControl1_OnExtentUpdated(object sender, IMapControlEvents2_OnExtentUpdatedEvent e){IEnvelope pEnv;//矩形面pEnv = e.newEnvelope as IEnvelope;IGraphicsContainer graphicscontainer;IActiveView activewer;graphicscontainer = axMapControl2.Map as IGraphicsContainer;activewer = graphicscontainer as IActiveView;graphicscontainer.DeleteAllElements();IElement plement;plement = new RectangleElementClass();plement.Geometry = pEnv;//设置矩形的属性IRgbColor rgbcol = new RgbColorClass();rgbcol.RGB = 255;rgbcol.Transparency = 255;//不透明边框ILineSymbol poutline = new SimpleLineSymbolClass();poutline.Width = 1;poutline.Color = rgbcol;IRgbColor pcolor = new RgbColorClass();pcolor.RGB = 255;pcolor.Transparency = 0;//透明内部IFillSymbol fillsym = new SimpleFillSymbolClass();fillsym.Color = pcolor;fillsym.Outline = poutline;//IFillShapeElement这个接口可以添加symbol。IFillShapeElement pfillshapeelement;pfillshapeelement = plement as IFillShapeElement;pfillshapeelement.Symbol = fillsym;//添加矩形框plement = pfillshapeelement as IElement;//转回为IElement才能在map2中添加矩形框graphicscontainer.AddElement(plement, 0);//添加activewer.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);//视图刷新}
