title: Saving a trie to disk
body: <p>This sounds like a simple question, but I don't know how to search for its answer.</p>
  
  <p>I have a trie implementation in C# that will store about 80K words from a dictionary file. It takes quite a while to load all these words (more than 5 mins). I was wondering, what is the best way to "persist" those data so I don't have to reload all words every time I start the application?</p>
  
  <p>Thanks. </p>
