VC++ .NET 2003学习

先学习了一个例子，面向对象的
#include "stdafx.h"

#using <mscorlib.dll>

using namespace System;

__gc class Animal
{
public:
    int    legs;
    void SetName(String *name) 
             { strName = strName->Copy(name); }
    String* GetName() { return strName; }
private:
    String *strName;
};

int _tmain()
{
    // TODO: Please replace the sample code below with your own.
    Animal *cat, *dog;
    cat = new Animal;
    dog = new Animal;

    cat->SetName("Cat");
    cat->legs = 4;
    dog->SetName("Dog");
    dog->legs = 4;

    Console::WriteLine("Animal 1");
    Console::Write("Name: ");
    Console::WriteLine(cat->GetName());
    Console::Write("Legs: ");
    Console::WriteLine(cat->legs);
    Console::WriteLine();
    Console::WriteLine("Animal 2");
    Console::Write("Name: ");
    Console::WriteLine(dog->GetName());
    Console::Write("Legs: ");
    Console::WriteLine(dog->legs);
    Console::WriteLine();

    return 0;
}

很好的一个例子，用到了托管代码，__gc,要注意的是，调试时，用到了托管代码，所以要在
项目->属性->c/c++选项->常规->编译为托管     选择   程序集支持   (/clr)  
就可以了，值得初学者注意
