C++CLI调用ArcObjects (3)

#pragma once

#include \ using namespace System; namespace NAoWrapper { }

public ref class RefAoWrapper { };

// TODO: Add your methods for this class here. AoHelper *ao; int line_test(); RefAoWrapper(); ~RefAoWrapper(); private: public:

修改NAoWrapper.cpp

// This is the main DLL file.

#include \ #include \

using namespace System::Diagnostics;

namespace NAoWrapper {

int RefAoWrapper ::line_test() {

Stopwatch^ watch=gcnew Stopwatch(); watch->Start();

RefAoWrapper::~RefAoWrapper() { }

delete ao;

RefAoWrapper::RefAoWrapper() { }

ao=new AoHelper();

}

}

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AoWrapperDemo\\Debug目录

添加ESRI.AcrGIS.相关引用 添加项目引用

修改Program.cs

using System; using ESRI.ArcGIS;

using ESRI.ArcGIS.esriSystem;

namespace Test {

static class Program {

///

static void Main() {

if (!RuntimeManager.Bind(ProductCode.Engine))
