Removing Items From A Container In A Foreach Loop

It wouldn’t have been unrealistic for the designers of .NET to find a way to make this work:

foreach( Item i in ItemList )
{
  if( i.ShouldBeRemoved )
  {
    ItemList.Remove(i);
  }
}

What happens is you get a ‘collection modified’ exception and you’re hosed. You can’t move to the next item in the list because removing the item broke the list. It wouldn’t have been that hard for the design of IEnumerable (the thingy that makes foreach possible) to keep track of where the next item was even after a removal.

Instead of being able to use the above code, something like this clunky bit is required:

for( int i = (ItemList.Count – 1); i >= 0; i– )
{
  if( i.ShouldBeRemoved )
  {
    ItemList.Remove(i);
  }
}

It’s like telling someone they can avoid head-on car collisions by always driving in reverse.

Anyhow, there was a bit of a problem with the Select() command and socket management, and this was the solution. The socket code is now functional and stable enough that I can log in and run around trying to play the game. It’s not terribly playable yet — I have a *LOT* more work to do, but it’s still theoretically possible that a development server could go up i mid-but-more-likely-late May.
