Should a .NET generic dictionary be initialised with a capacity equal to the number of items it will contain?

Question

If I have, say, 100 items that\'ll be stored in a dictionary, should I initialise it thus?

var myDictionary = new Dictionary(100);
<

I think you're over-complicating matters. If you know how many items will be in your dictionary, then by all means specify that on construction. This will help the dictionary to allocate the necessary space in its internal data structures to avoid reallocating and reshuffling data.
