How to Elegantly code an if()?

[Traps]

I dont know if delegates can do this in c#. Pretty sure you can in c++ using function pointers. The concept is basically this (NOT ACTUAL CODE):

 
class myClass
{
    private PointerType goHere = AddressOf(Sub1)
    private void Main()
    { 
        goHere
    }
 
    private void Sub1()
    {
        if ( your condition )
        {
            goHere = AddressOf(Sub2)
        }
    }
 
    private void Sub2()
    {
    }
}
