Member offset pointers ?

[Adam Benson]

Hi,

In C++ you could define a member offset pointer which worked on any instance
of a class.

i.e.
class MyClass
{
int IntOne;
int IntTwo;

void SetInt(int MyClass::* p)
{
this->*p = 100;
}
}

void Eg()
{
MyClass c;

// Sets c.IntOne
c.SetInt(&MyClass::IntOne);
// Sets c.IntTwo
c.SetInt(&MyClass::IntTwo);
}

A rather simplistic illustration, and my apologies if the syntax isn't
exactly right - I haven't worked with C++ for a couple of years. Is there
anything like this in C# ? I've searched and can't find it.

Thanks,

Adam.

you can pass things by reference using the ref keyword. This enables you to
pass a member variable to a function and have that function update the member
variable.
e.g

void SetInt(ref int p)
{
p = 100;
}
