如何更改此代码以获得最长的连续 C 序列，而不是任何字符的最长连续序列

问：

我做了一个解决方案，为我提供了最长的连续字符序列的值，但是我需要如何修改它以指定我需要字符 C 的最长连续序列？或者我完全需要一个全新的代码块？

namespace CarCounting
{
    internal class Program
    {
        static void Main(string[] args)
        {
            CarCounting newSequence = new CarCounting();   
            Console.WriteLine(newSequence.longest("CCMCCCCLLCCC")); //executes the function
  
        }
    }

    public class CarCounting
    {

        public CarCounting()
        {

        }


        public int longest(string mySequence)
        {
            //turns the argument into an array
            char[] charC = new char[mySequence.Length]; 
            for (int i = 0; i < mySequence.Length; i++) 
            {
                charC[i] = mySequence[i];
            }

            int charCcount = 0;
            int length = charC.Length;
            
            //compares the values in the array
            for(int i = 0; i < length; i++)  
            {
                int currentcount = 1;
                for (int j = i + 1; j < length; j++) 
                {
                    if (charC[i] != charC[j]) 
                        break;
                    currentcount++;
                }
                if (currentcount > charCcount)
                {
                    charCcount = currentcount;
                }
            }


            return charCcount;

        }

    }

}
