C# switch/break

Yes, you can fall through to the next case block in two ways. You can use empty cases, which don't need a break, or you can use goto to jump to the next (or any) case:

switch (n) {
  case 1:
  case 2:
  case 3:
    Console.WriteLine("1, 2 or 3");
    goto case 4;
  case 4:
    Console.WriteLine(4);
    break;
}

The enforcement of "break" is there to stop bugs. If you need to force a fall-thru then use "goto case " (replace the with appropriate value)

the following example shows what you can do:

switch(n)
{
    case 1:
    case 2:
      //do something for 1+2
      //...
      goto case 3;
    case 3:
      //do something for 3, and also extra for 1+2
      //...
      break;
    default:
      //do something for all other values
      //...
      break;
}

C# doesn't support implicit fall through construct, but the break (or goto) nonetheless has to be there (msdn). The only thing you can do is stack cases in the following manner:

switch(something) {
    case 1:
    case 2:
      //do something
      break;
    case 3:
      //do something else
}

but that break (or another jump statement like goto) just needs to be there.
