Collection was modified

Many times i’m programming and i want to iterate a collection and modify it. Thsi usually happens when i want to remove a certain number of objects of a collection:

foreach( Element e in elements){
   if( ConditionIsSatisfied(e) ) {
       elements.Remove(e);
   }
}

The above method will give a collection modified exception because i’m modifying a collection while iterating it.

To resolve this problem without long lines of code, there is a simple thing i can do:

List<Element> temporayElements = new List<Element>(elements);
foreach( Element e in temporayElements){
   if( ConditionIsSatisfied(e) ) {
       elements.Remove(e);
   }
}

This way, i can iterate and check the conditions in one container and manipulate the original one without the possibility of throwing a “Collection was modified” exception.

Cinema In 2009

This year Will be wonderful for me. Action and Sci Fi movies with a lot of special effects are my favorite and 2009 is full of them.

Here are some:

Terminator Salvation - Hope this movie marks the long awaited changed in the terminator saga (This time without Arnold in the way!).

Transformers: Revenge of the Fallen - If the first was wonderful, the second i hope it will be fantastic!(Sometimes this isn’t true… Well we will be here to see…)

X-Men Origins: Wolverine - My favorite character of all the marvel universe. Can’t wait for the premiere.

Star Trek - Has a fan, i hope this movie brings a new beginning for the Star Trek saga.

Street Fighter: The Legend of Chun-Li - This is one of “those” movies… I want to watch because i’m a huge fan of Street Fighter… But i’m afraid… Very very afraid…

Dragon Ball Evolution - This is another of “those” movies. The trailer suggests a wonderful action movie, with a lot of fights dragon ball style! But there are some unforgivable errors like Bulma’s hair for instance…

Underworld: Rise of the Lycans - Loved the first, loved the second. A great saga now with an untold story: How the Lycans and the Vampires became mortal enemies!
