simple way of continuing out of outter loop

[Jon Slaughter]

Say I have two nested foreach loops, is there any simple way of continuing
out of the outter most loop depending on what happens in the inner most?

e.g.,

foreach(int i in I)
{
foreach(int j in J)
if (j == 3)
break.continue;
}

where break.continue means break out of inner loop and continue in outter
loop.

I doubt such a thing exists but just curious

Thanks,
Jon

Well, you *could* use a goto, if you absolutely had to. I'd normally
try to design my way around it though (to allow a return statement to
work, for instance), or set a boolean flag which the outer loop can
notice and break.

Yeah, I was trying to avoid the bool flag. In fact what I did was juse a
function to do the inner loop since it was just a test.

// Checks if types of A is of type Q for each element in the container
private bool ContainsType<A, Q>(IEnumerable list)
{
foreach (A a in list)
if (a is Q)
return true;
return false;
}

So that is for my inner loop. More work than setting a flag but more
general. (the only real issue is if I'm checking more than one type in the
list I'm wasting cycles ;/ Maybe a flag would have been better ;/ (I think
though for my specific situation I'll only have to use the function a few
times at most so maybe the clarity is better)

With the code you showed, just "break;" will do exactly that (because the
inner loop is the last statement block in the outer loop body).

Doh! Misread the question, assuming Mr Slaughter wanted to break out
of both. Oops!
