c# - Random entry from dictionary

Question

What is the best way to get a random entry from a Dictionary in c#?

I need to get a number of random objects from the dictionary to display on a page, however I cannot use the following as dictionaries cannot be accessed by index:

Random rand = new Random();
Dictionary< string, object> dict = GetDictionary();
return dict[rand.Next()];

Any suggestions?

If you're using .net 3.5, Enumerable has an extension method ElementAt which would allow you to do:

return dict.ElementAt(rand.Next(0, dict.Count)).Value;
