How To Modify An Element in the Dictionary Class?
=======================================
C# has this cool Dictionary class that you can use like a Hash Table. Is there a way of changing the value of an indexed element without resorting to removing it like this?

Code:

 
               int value = runningcount[city];
               runningcount.Remove(city);
               runningcount.Add(city, ++value);

What about using an indexer?

Code:

            string city = "Vienna";
            var runningCount = new Dictionary<string, int>();
            runningCount[city] = 33;
            runningCount[city]++;
            Console.WriteLine(runningCount[city]);
