title: What's Wrong with an ArrayList?
body: <p>Recently I asked a question on SO that had mentioned the possible use of an c# ArrayList for a solution. A comment was made that using an arraylist is bad. I would like to more about this. I have never heard this statement before about arraylists. 
  could sombody bring me up to speed on the possible performance problems with using arraylists</p>
