各位高手,帮我看看这程序是怎么回事!

// DelegateExample.cpp: 主项目文件。

#include "stdafx.h"

using namespace System;
delegate double CalculatorDelegate(double,double);
ref class Calculator
{
public:
static double Add(double a,double b)
{
return a+b;
}
};
int main(array<System::String ^> ^args)
{
CalculatorDelegate *add=gcnew CalculatorDelegate(0,&Calculator::Add);
Console::WriteLine(L"Hello World");
return 0;
}

using namespace System; 

delegate double CalculatorDelegate(double,double); 
ref class Calculator 
{ 
public: 
    static double Add(double a,double b) 
    { 
        return a+b; 
    } 
}; 
int main(array <System::String ^> ^args) 
{ 
    CalculatorDelegate ^add = gcnew CalculatorDelegate(&Calculator::Add); 
    Console::WriteLine(L"Hello World"); 
    return 0; 
}

看上去 delegate 像是C#里的东西

delegate double CalculatorDelegate(double,double);
是定义一个返回函数指针的CalculatorDelegate函数

后面的东西就不难理解了

谢谢,我想问一下,那个函数不是要有两个参数吗?
