1.类的三要素：属性，方法，事件。

2.对象：对象是客观世界中的事物或人们头脑中的各种概念在计算机程序中的抽象表示，或者说，是现实世界中个体的数据抽象模型，是面向对象程序设计的基本元素。

3.ArcGIS 框架：包含workstation和Desktop，ArcGIS组成：Desktop、Engine、Server GIS、Mobile GIS。

Desktop三种级别许可：ArcView、ArcEditor、ArcInfo。

4.AO的三种开发模式：（1）Based on ArcGIS Desktop（2）Based on ArcGIS Engine（3）Based on ArcGIS ServerArcObjects Developing MethodsDeskTop Customizingin VBA IDE to Customize ArcInfo Desktop..Net Independent ApplicationMethod1:Develop Independent Applications Based on ArcObjects butDesk must Run when the Application is executed.Method2:Develop Independent Applications Based on ArcEngine and DeskIs Unnecessary When the Application Is Executed.COM GISBuild Some COM Modules to Implement Some FunctionsReusable.5.ArcGIS的数据管理：（1）Document File mxt（地图模板）、mxd（地图文档）。

（2）Layer File lyr 图层对象是获得数据的引用（3）数据类型（重点）矢量类型（Shapefile、Coverage、Geodatabase、Dwg/Dxf、Dgn、vpf）栅格类型（grid、SDE raster、RasterCatalogs、img、tif、png、jpg）TinPrj（坐标文件）Relationship6.Geodatabase的三种格式File Geodatabase：文件型地理数据库Personal Geodatabase：个人地理数据库ArcSDE Geodatabase：ArcSDE地理数据库区别：空间数据库有7.抽象类：不能被实例化，只能被继承。

是一组内建属性、接口和方法的对象。

组件类：可用new方法创建。

实例化类：不能用new方法创建，只能作为另一个类的属性或被其他类的对象实例化类之间的关系如图所示：继承关系（inheritance），实例化（Instantiation），组成关系（Composition），关联关系（Association）8.4种颜色坡道：1.AlgorithmicColorRamp通过指定起始颜色、终止颜色确定一个颜色带，起始、终止颜色使用HSV模型。

2.MultiPartColorRamp：是叠加产生颜色带。

3.RandomColorRamp：产生随机颜色带。

4.PresetColorRamp：使用HSV颜色模型来产生一串颜色预设的颜色模式，可存储13种颜色。

4种颜色模式：（RGB、CMYK、HSV、Gray）Segmen:BezierCurve CircularArc EllipticArc LineRenderer对象：FeatureRenderer中常用的Renderer类：ClassBreakRenderer（分级渲染）UniqueValueRenderer（唯一值渲染）ProportionalSymbolRendererChartRendererDotDensityRendererRasterRenderer中的类：RasterRGBRenderer（栅格RGB符号化）RasterUniqueValueRenderer（唯一值符号化）RasterClassifyColorRampRenderer（分类符号化）RasterStretchColorRampRendererRasterDiscreteColorRenderer（点密度符号化）Element中的类：图形元素（Graphic Element）和框架元素（Frame Element） Graphic：LineElement（Symbol、Geometry），MarkerElement（Symbol）TextElement（ScaleText，Text，Symbol），GroupElement, FillShapeElement（抽象类，泛化为PolygonElement等），图片对象FrameElement:MapFrame（Map的容器，用于管理Map。

Map属性，MapBounds属性,MapScale属性，CreateSroundFrame（）），MapSurroundFrame (用于管理比例尺等)MapGrid：地图网格由GridLine，GridLabel，GridBorder组成注：对下面的英文的翻译可能会用不对的地方What Are the Differences between Comand ActiveX Control ?继承的类不同Application TypeDesign InterfaceCode StandardAdd Reference Method.NET Com Developing StepsCOM DesigningBuild COM Application in .Net IDE（在.net继承环境中创建Com应用程序）Add Classes（添加类）Create Attributes , Methods and Events（创建属性方法，事件）Write Code to Complete Some Functions（完成一些函数）Debug COM App （调试Com应用程序）COM Debugging and TestingBuild Windows Application in .Net IDE（在.net集成环境中创建Windows应用程序）Add Reference of COM Built last（添加新建的Com组件的引用）Create COM Object（创建Com组件中类的对象）Write Code to Complete Some Functions（完成一些函数）Debug COM App 调试Com应用程序.NET ActiveX Developing StepsActiveX Control DesigningBuild ActiveX Control Application in .Net IDE（在.net继承环境中创建ActiveX Control 应用程序）Design Interface（设计界面）Set Attributes , Methods and Events（设置属性，方法，和事件）Write Code to Complete Some Functions（完成一些函数）Debug ActiveX Control(调试ctiveX Control)ActiveX Controls Debugging and TestingBuild Windows Application in .Net IDE（在.net继承环境中创建窗体应用程序）Add Reference of ActiveX Control Built last（添加新建的ActiveX控件的引用）Add ActiveX Controls to Forms（将ActiveX控件添加到窗体中）Set Attributes , Methods and Events（设置属性，方法，和事件）Write Code to Complete Some Functions（完成一些函数）Debug Windows App （调试应用程序）Com组件的特点：common properties:OO Ideas（面向对象的思想）C/S Structure（c/s的构建）Language independent（语言独立性）Processing Transparency程序处理透明Code Reusable 代码可重用性Special properties:Code Auto-Generated on COM StandardExecuted On .Net Framework 在framework中运行Executed without Register 不需要在注册表中注册就可以运行Debugged and Tested in Windows Application Programs 在windows 应用程序中调试和测试.NET ActiveX Control 特点common properties:OO IdeasLanguage independentProcessing TransparencyCode ReusableUsed As Tools 作为工具使用（此处说的工具即vs中工具箱中的工具） Special properties:Executed without RegisterDebugged and Tested in Windows Application ProgramsReference As ActiveX Controls常用的控件：(可能还要考这些控件的属性和方法，我一时也想不到，大家自己找找吧)MapControl ：MousePinter属性,Extent属性,FullExtent属性,ChecMxFile（）方法，LoadMxdFile（）方法,AddLayer（）方法,DeleteLayer（）,MoveLayerToAddlayerFromFile()方法,AddShanpeFile（）方法,ReadM下Maps（）方法PageLayoutControl：Printer属性，Page属性，Element属性（用于管理控件中的地图元素）,SceneControl：GlobeControl：ToolBarControl: Buddy属性TOCControl:Buddy属性private void LoadMapDocument3()//{IMapDocument mapDocument = new MapDocumentClass();System.Windows.Forms.OpenFileDialog openFileDialog;openFileDialog = new OpenFileDialog();openFileDialog.Title = "打开地图文档";openFileDialog.Filter = "map documents(*.mxd)|*.mxd";openFileDialog.ShowDialog();string filePath = openFileDialog.FileName;if (axMapControl1.CheckMxFile(filePath)){mapDocument.Open(filePath, null);}if(mapDocument.MapCount>0){for (int i = 0;
