How to break out of multiple loops at once in C#?

Question

What if I have nested loops, and I want to break out of all of them at once?

while (true) {     // ...     while (shouldCont) {         // ...         while (shouldGo) {             // ...             if (timeToStop) {                 break; // Break out of everything?             }         }     } } 

In PHP, break takes an argument for the number of loops to break out of. Can something like this be done in C#?

What about something hideous, like goto?

// In the innermost loop goto BREAK // ... BREAK: break; break; break; 

Answer 1

Extract your nested loops into a function and then you can use return to get out of the loop from anywhere, rather than break.

Answer 2

Introduce another control flag and put it in all your nested while condition like below. Also replaces the while(true) condition you have with that

bool keepLooping = true; while (keepLooping) {     // ...     while (shouldCont && keepLooping) {         // ...         while (shouldGo && keepLooping) {             // ...             if (timeToStop) {                  keepLooping  = false;                 break; // break out of everything?             }         }       } }
