title: C# dictionary vs list usage
body: <p>I had two questions. I was wondering if there is an easy class in the C# library that stores pairs of values instead of just one, so that I can store a class and an integer in the same node of the list. I think the easiest way is to just make a container class, but as this is extra work each time. I wanted to know whether I should be doing so or not. I know that in later versions of .NET ( i am using 3.5) that there are tuples that I can store, but that's not available to me.</p>
  
  <p>I guess the bigger question is what are the memory disadvantages of using a dictionary to store the integer class map even though I don't need to access in O(1) and could afford to just search the list?  What is the minimum size of the hash table? should i just make the wrapper class I need?</p>
