Playing with the DuplicateCount kata

That's my first kumite... don't really know what all this is about...

using System;
using System.Linq;

public class Kata
{
      public static int DuplicateCount(string str)
      {
            var orderedLowercase = str.ToLower().OrderBy(c => c);
            var countDuplicates = 0;
            var countOccurrenciesCurrentCharacter = 1;
            char? previousElement = null;
            var firstElement = true;

            foreach(var currentElement in orderedLowercase)
            {
                if (firstElement)
                {
                    firstElement = false;
                }
                else
                {
                    if (currentElement == previousElement.Value)
                    {
                        countOccurrenciesCurrentCharacter ++;

                        if (countOccurrenciesCurrentCharacter == 2)
                        {
                            countDuplicates ++;
                        }
                    }
                    else
                    {
                        countOccurrenciesCurrentCharacter = 1;
                    }
                }
                previousElement = currentElement;
            }
            return countDuplicates;
      }
