.NET Program to count the number of occurrences of a Character in a String

The program returns number of occurrences of a particular character/letter in a string/sentence.

E.g: "HELLO WORLD" - character 'L'  count = 3

Program:

namespace DotNetMirror
{
    class NoOfTimesLetterAppearedInSentence
    {
        public static void Main()
        {
            char letterToFind = 'r';
            string sentence = "dotnetmirror reflects your knowledge";
            int count = GetLetterCountInSentence(letterToFind, sentence);
            Console.WriteLine("letter '{0}' found {1} times in '{2}'",letterToFind,count, sentence);
            Console.ReadLine();
        }
        public static int GetLetterCountInSentence(char letter, string sentence2check)
        {
            int noOfTimes=0;
            for (int i = 0; i < sentence2check.Length; i++)
            {
                if (sentence2check[i] == letter)
                {
                    noOfTimes += 1; //if found, increase the count
                }
            }
            return noOfTimes; //returns the count of noOfTimes
        }
    }
}

Output:
