Breaking out of a foreach loop from within a switch block

Question

How do you break out of a foreach loop while within a switch block?

Normally, you use break but if you use a break within a switch block it will just get you out of a switch block and the foreach loop will continue execution:

foreach (var v in myCollection) {     switch (v.id)     {         case 1:             if (true)             {                 break;             }             break;         case 2;             break     } } 

What I'm currently doing when I need to break out of the foreach while within the switch block is setting a bool value placed outside of the loop to true and checking the value of this bool every time the foreach is entered and before entering the switch block. Something like this:

bool exitLoop; foreach (var v in myCollection) {     if (exitLoop) break;     switch (v.id)     {         case 1:             if (true)             {                 exitLoop = true;                 break;             }             break;         case 2;             break     } } 

This works but I keep thinking there must be a better way of doing this I am unaware of...

EDIT: Wonder why this was not implemented in .NET the really neat way it works in PHP as mentioned by @jon_darkstar?

$i = 0; while (++$i) {     switch ($i) {     case 5:         echo "At 5<br />\n";         break 1;  /* Exit only the switch. */     case 10:         echo "At 10; quitting<br />\n";         break 2;  /* Exit the switch and the while. */     default:         break;     } }

Your solution is pretty much the most common option in this case. That being said, I'd put your exit check at the end:

bool exitLoop; foreach (var v in myCollection) {     switch (v.id)     {         case 1:             if (true)             {                 exitLoop = true;             }             break;         case 2;             break     }      // This saves an iteration of the foreach...     if (exitLoop) break; } 

The other main option is to refactor your code, and pull the switch statement and foreach loop out into a separate method. You could then just return from inside the switch statement.
