I guess you could have a boolean flag as part of the while loop, bool isBreakingFromDefault, and just set that flag to true when you break from default. When the while loop sees that flag as true, break from the while loop as well. FWIW, I think the switch construct is butt ugly and often confusing. I'd much rather see a few if/elses.

I could certainly be missing something but I thought this was for VB not C#.

only two letters away from being an asset

:confused: There's an exit keyword in C#?

It's from C# language specification: When multiple switch, while, do, for, or foreach statements are nested within each other, a break statement applies only to the innermost statement. To transfer control across multiple nesting levels, a goto statement (§8.9.3) must be used. using System; class Test { static void Main(string[] args) { string[,] table = { {"Red", "Blue", "Green"}, {"Monday", "Wednesday", "Friday"} }; foreach (string str in args) { int row, colm; for (row = 0; row <= 1; ++row) for (colm = 0; colm <= 2; ++colm) if (str == table[row,colm]) goto done; Console.WriteLine("{0} not found", str); continue; done: Console.WriteLine("Found {0} at [{1}][{2}]", str, row, colm); } } }

Ahhhh! Not the notorious goto! X|

Even though you already mentioned this, it's short, and pretty much the standard: bool bContinue = true; while( myOtherCriteria && bContinue) { case... ... ... otherwise: bContinue = false; }

To be weirder, you can throw an exception...:):):)

Well, I don't much like goto myself but that's the way Microsoft specifications provide. The good thing is that at least all finally blocks are still processed so not much harm is done. Sometimes goto is far more comprehensive than additional boolean flags and checks in nested loops.

Wow - I think the reverse. They are, of course, the same thing in the end.

C# seems to break down a little.

Actually, I don't think this has anything to do with C# per se. C and C++ work the same way. /ravi

It's not notorious when used to branch to the end of a block. In fact, that's what break and return do. Djikstra's paper has to do with branching into a control block, there making program verification orders of magnitude more difficult. /ravi

:wtf: the switch is excellent, but not really usable in every case, but so are if/elses. Just use the right tool for the job :).
