C++调用ArcObjects

1新建一个空的工程命名为AoWrapperDemo2 添加一个新项目，命名为AoWrapper右键项目-属性，添加ESRI.ArcGIS相关引用将配置类型改为动态链接库添加一个c+文件，命名为GeometryWrapper由于该类功能简单，没必要添加头文件using namespace System;using namespace System:Diagnostics;using namespace ESRI:ArcGIS:Geometry;using namespace ESRI:ArcGIS:esriSystem;using namespace ESRI:ArcGIS;namespace AoWrapperpublic ref class GeometryWrapperpublic:GeometryWrapper()ESRI:ArcGIS:RuntimeManager:Bind(ProductCode:Engine);IAoInitialize pAoInitialize=gcnew AoInitializeClass();pAoInitialize-Initialize(esriLicenseProductCode:esriLicenseProductCodeEngineGeoDB);GeometryWrapper()public:int line_test()IPoint ipPt1 =gcnew PointClass();IPoint ipPt2 =gcnew PointClass();ipPt1-PutCoords(1, 2);ipPt2-PutCoords(2, 3);ILine ipLine=gcnew LineClass();Stopwatch watch=gcnew Stopwatch();watch-Start();for(long i=0;iPutCoords(ipPt1,ipPt2);/Console:WriteLine(i);watch-Stop();Console:WriteLine(watch-ElapsedMilliseconds);return 0;完成C+/CLI对ArcObjects的调用封装类库3 添加一个新项目，命名为NAoHelper，利用本地c+直接操作AO修改头文件stdafx.h，导入ArcObjects相关库/ stdafx.h : include file for standard system include files,/ or project specific include files that are used frequently, but/ are changed infrequently/#pragma once#include targetver.h#define WIN32_LEAN_AND_MEAN / Exclude rarely-used stuff from Windows headers/ Windows Header Files:#include / TODO: reference additional headers your program requires here#pragma warning(push)#pragma warning(disable : 4192) /* Ignore warnings for types that are duplicated in win32 header files */#pragma warning(disable : 4146) /* Ignore warnings for use of minus on unsigned types */#import C:Program Files (x86)ArcGISDesktop10.1comesriSystem.olb raw_interfaces_only, raw_native_types, no_namespace, named_guids, exclude(OLE_COLOR, OLE_HANDLE, VARTYPE)#import C:Program Files (x86)ArcGISDesktop10.1comesriGeometry.olb raw_interfaces_only, raw_native_types, no_namespace, named_guids,exclude(OLE_COLOR)/ Load the ArcGISVersion library./ This code is commonly placed in the StdAfx.h header file.#import libid:6FCCEDE0-179D-4D12-B586-58C88D26CA78 raw_interfaces_only,no_implementation添加一个头文件NAoHelper.h修改后的头文件如下：#ifndef AOHELPER_H_#define AOHELPER_H_#ifdef NAOHELPER_EXPORTS#define DAPI _declspec(dllexport)#else#define DAPI _declspec(dllimport)#endif/导出这个类class DAPI AoHelperpublic: AoHelper(); AoHelper(); int line_test();private:int InitializeAo();#endif打开NAoHelper.cpp，修改后如下：/ NAoHelper.cpp : Defines the exported functions for the DLL application./#include stdafx.h#include NAoHelper.hAoHelper:AoHelper():CoInitialize(NULL);/不初始化也可以/InitializeAo();AoHelper:AoHelper():CoUninitialize();int AoHelper:InitializeAo()ArcGISVersionLib:IArcGISVersionPtr ipVer(_uuidof(ArcGISVersionLib:VersionManager);VARIANT_BOOL succeeded;if (FAILED(ipVer-LoadVersion(ArcGISVersionLib:esriArcGISDesktop , L10.1,&succeeded)return 0;IAoInitializePtr m_AoInit;/(CLSID_AoInitialize);m_AoInit.CreateInstance (CLSID_AoInitialize);esriLicenseStatus ls;HRESULT h= m_AoInit-Initialize(esriLicenseProductCode:esriLicenseProductCodeEngineGeoDB ,&ls);return 0;int AoHelper:line_test()IPointPtr ipPt1(CLSID_Point);IPointPtr ipPt2(CLSID_Point);ipPt1-PutCoords(1, 2);ipPt2-PutCoords(2, 3);ILinePtr ipLine(CLSID_Line);for(long i = 0; i PutCoords(ipPt1,ipPt2);return 0;编译，完成本地c+调用AO封装类库4 添加新项目，命名为NAoWrapper，利用C+/CLI对NAoHelper进行封装的库，以便于C#调用编辑包含文件（头文件）目录修改头文件NAoHelper.h/ NAoWrapper.h#pragma once#include NAoHelper.husing namespace System;namespace NAoWrapper public ref class RefAoWrapper/ TODO: Add your methods for this class here.private:AoHelper *ao;public:int line_test(); RefAoWrapper(); RefAoWrapper();修改NAoWrapper.cpp/ This is the main DLL file.#include stdafx.h#include NAoWrapper.husing namespace System:Diagnostics;namespace NAoWrapper RefAoWrapper:RefAoWrapper()ao=new AoHelper();RefAoWrapper:RefAoWrapper()delete ao;int RefAoWrapper :line_test()Stopwatch watch=gcnew Stopwatch();watch-Start();ao-line_test();watch-Stop();Console:WriteLine(watch-ElapsedMilliseconds);return 0;5 添加新项目，命名为CSharpAoHeleper，C#直接调用ArcObjects添加ESRI.ArcGIS.相关引用将Class1.cs重命名为CSharpAoHeleper，代码如下using System;using System.Collections.Generic;using System.Linq;using System.Text;using ESRI.ArcGIS.Geometry;using System.Diagnostics;namespace CSharpAoHeleper public class CSharpAoHeleper public int line_test() IPoint ipPt1 = new PointClass(); IPoint ipPt2 = new PointClass(); ipPt1.PutCoords(1, 2); ipPt2.PutCoords(2, 3); ILine ipLine = new LineClass(); Stopwatch watch = new Stopwatch(); watch.Start(); for (long i = 0; i = 10000000; i+) ipLine.PutCoords(ipPt1, ipPt2); /Console:WriteLine(i); watch.Stop(); Console.WriteLine(watch.ElapsedMilliseconds); return 0; 编译，完成C#直接操作AO封装库6 添加新项目，命名为Test右键项目属性，修改输出路径（Output path）：即AoWrapperDemoDebug目录添加ESRI.AcrGIS.相关引用添加项目引用修改Program.csusing System;using ESRI.ArcGIS;using ESRI.ArcGIS.esriSystem;namespace Test static class Program / / The main entry point for the application. / STAThread static void Main() if (!RuntimeManager.Bind(ProductCode.Engine) if (!RuntimeManager.Bind(ProductCode.Desktop) Console.WriteLine(Unable to bind to ArcGIS runtime. Application will be shut down.); return; IAoInitialize pAoInitialize = new AoInitializeClass(); esriLicenseStatus licenseStatus = pAoInitialize.Initialize(esriLicenseProductCode.esriLicenseProductCodeEngine); if (licenseStatus != esriLicenseStatus.esriLicenseCheckedOut) return; Console.WriteLine(进行10000000次运算测试rn); Console.WriteLine(=C+/CLI测试开始=); AoWrapper.GeometryWrapper geo = new AoWrapper.GeometryWrapper(); geo.line_test(); Console.WriteLine(=C+/CLI封装本地Api测试开始=); NAoWrapper.RefAoWrapper refAoWrapper = new NAoWrapper.RefAoWrapper(); refAoWrapper.line_test(); Console.WriteLine(=C#测试开始=); CSharpAoHeleper.CSha
