Maybe this is what Luc was getting at

Int32 someInt = 6;
SomeMethod(ref someInt);
MessageBox.Show("SomeInt now contains value" + someInt.ToString()); // It has value of 12
// And now for method
public void SomeMethod(ref Int32 data)
{
	data = data * 2;
}

I did think of bringing that up, but when would you be able to alter the value from outside the function while the function is running? You would need multi-thread, in which case there would be other issues.
