How to break out of an if statement from a boolean inside the if statement

Question

I have something like this

bool a = true;
bool b = true;
bool plot = true;
if(plot)
{
    if(a)
    {
        if(b)
            b = false;
        else
            b = true;
    //do some meaningful stuff here
    }
//some more stuff here that needs to be executed
}

I want to break out of the if statement that tests a when b turns false. Kind of like break and continue in loops. Any ideas? Edit: sorry forgot to include the big if statement. I want to break out of if(a) when b is false but not break out of if(plot).

This makes no sense. There is nothing to "break" out from. This is not a loop. Either the precondition for a is true prior to executing the "if(a)" and the code in the statement is executed, or it is false, and the code is not executed. Please re-write your question. — OldProgrammer, Jul 18 '13 at 15:28
This looks like quite enough logic to be put in a method of itself. So you could just `return` from that. — Corak, Jul 18 '13 at 15:28
just put brackets around your inner if like your outer if. And you will 'break' out. I think you are overthinking. — Jonesopolis, Jul 18 '13 at 15:29
@NewDev - since that was an actual answer (which was quickly deleted because of downvotes; so i don't mean you directly): if `goto` is the solution, you have more problems than you are aware of. It's a very good indicator to start refactoring immediately! — Corak, Jul 18 '13 at 15:52

You can extract your logic into separate method. This will allow you to have maximum one level of ifs:

private void Foo()
{
   bool a = true;
   bool b = true;
   bool plot = true;

   if (!plot)
      return;

   if (a)
   {
      b = !b;
      //do something meaningful stuff here
   }

   //some more stuff here that needs to be executed   
}

if(plot)
{
    if(a)
    {
        b= !b;
        if( b )
        {
            //do something meaningful stuff here
        }
    }
    //some more stuff here that needs to be executed
}

Needs more if nesting! – MrDosu Jul 18 '13 at 15:45

Was going for minimal change from the original. – Denise Skidmore Jul 18 '13 at 18:51

bool a = true;
bool b = true;
bool plot = true;
if(plot && a)
{
  if (b)
    b = false
  else
    b = true;

  if (b)
  {
    //some more stuff here that needs to be executed
  }
}

This should do what you want ..
