==Call a Base Method==

<source lang="csharp">
#include "stdafx.h"
#using <mscorlib.dll>
using namespace System;
class Base {
public:
virtual ~Base() {
Console::WriteLine("Base cleanup");
};
};
class Derived : public Base {
public:
virtual ~Derived() {
Console::WriteLine("Derived cleanup");
};
};
int main(void) {
Derived instance;
return 0;
}

</source>

==Derive a Class==

<source lang="csharp">
#include "stdafx.h"
#using <mscorlib.dll>
using namespace System;
class BaseClass {
public:
virtual void MyFunction() {
Console::WriteLine("Inside Base class");
}
};
class DerivedClass : public BaseClass {
public:
virtual void MyFunction() {
Console::WriteLine("Inside Derived class");
}
};
void main() {
BaseClass base;
DerivedClass derived;
base.MyFunction();
derived.MyFunction();
}

</source>

==Finalizers and inheritance==

<source lang="csharp">
#include "stdafx.h"
using namespace System;
ref class Base
{
public:
Base() { }
~Base() { Console::WriteLine("~Base"); this->!Base(); }
!Base() { Console::WriteLine("!Base"); }
};
ref class Derived : Base
{
public:
Derived() { }
~Derived() { Console::WriteLine("~Derived"); this->!Derived(); }
!Derived() { Console::WriteLine("!Derived"); }
};
void F()
{
Derived d;
}
void G()
{
Derived^ dh = gcnew Derived();
}
int main()
{
F();
G();
Console::WriteLine("Collecting after G()");
GC::Collect();
}

</source>

==Inherit a class==

<source lang="csharp">
#include "stdafx.h"
using namespace System;
ref class Square{
public:
int Area(){
return Dims * Dims;
}
int Dims;
};
ref class Cube : public Square{
public:
int Volume(){
return Area() * Dims;
}
};
void main()
{
Cube ^cube = gcnew Cube();
cube->Dims = 3;
Console::WriteLine(cube->Dims);
Console::WriteLine(cube->Area());
Console::WriteLine(cube->Volume());
}
